[February 2026] VRChat Gimmick & Tool Trend Report on Booth

Here are the top 10 VRChat gimmick and tool releases from Booth in February 2026, sorted by likes and reviewed alongside the month's aggregate data. The free-release shift that started in January accelerated in February: 34 of the 77 monthly releases (about 44%) shipped free — up from 27% the previous month. Median price was ¥250 and median like count was 772, with the lineup mixing hair-chimera unification, a Unity-free avatar viewer, slider-driven body editing, an in-VR fisheye camera, mask painting, jiggle-bone auto-generation, a natural-language Unity AI agent, a logout effect, a ghost preset, and Unity-internal mesh editing. The gimmick & tool category's signature mix of editor extensions and runtime gimmicks was on full display. YuichaMart's January three-pick run was inherited in February by three different creators each placing two picks in the Top 10 — Banbi-no-Choujou (#1 + #5), Ajisai-Hiroba Works (#6 + #7), and Masakaniya (#3 + a supporting pick) — with three free releases inside the Top 10 itself.

10 Notable Gimmicks & Tools

Sorted by like count as of May 2026, with a closer look at what each release actually does and how it's built.

#1: Chimera Hair Master / Banbi-no-Choujou

A new release from Banbi-no-Choujou — the creator behind the popular "TexColorAdjuster" gimmick & tool — and a hair-chimera-specific helper that addresses "the colors don't match," "the materials are heavy," and "the positions drift" all in one workflow. At 8,177 likes it's February's top gimmick & tool, and the cover image directly states "Solve hair-chimera color mismatches non-destructively!"

The core feature surface is a three-piece set: color matching, mesh integration, and mask creation. Color matching ships in two modes — hue-shift mode (preserves shading detail while changing only the hue) and gradient mode (replaces the brightness curve entirely) — with adjustable preservation strengths for saturation and brightness. The v1.4.0 release in April switched the default color-conversion algorithm to OKLab, dramatically improving color-unification precision.

The mesh integration side delivers automatic texture-atlas generation (512–4096px) plus bone integration and rebinding to fundamentally cut the rendering cost when stacking hair prefabs together. v1.1 in March added a mesh deformer that lets hair be reshaped via mouse interaction at the UV island, vertex, or lattice level. It's a tool that grew from "match colors and merge geometry" toward "actually edit the silhouette" — chasing the next thing modders ask for once the basics are solved.

The product itself is ¥500 single edition / ¥600 full edition (Golden Week sale prices), with the full edition bundling the VCC distribution of #5 "Paint & Pick! Mask Maker" from the same creator. It's MIT-licensed and requires lilToon and NDMF (Modular Avatar). Five updates landed inside February (v1.0 on Feb 12 → v1.0.8 on Feb 15), with the mesh deformer, OKLab, prefab export, and stroke-feel unification features rolling out continuously through March, April, and early May — a textbook example of the high-frequency update cadence that defines this category's mod-support tools.

#2: VRC Avatar Viewer / Rob's Shop

A Windows-only standalone desktop app for opening and previewing avatars without Unity or the VRChat SDK installed. February's only Booth-distributed standalone application in the Top 10, designed so you can drag-and-drop a .vrc file (or a VRM) and see the avatar render immediately.

The feature scope goes far beyond passive viewing: transparent mode for desktop-mascot use / NDMF support so Modular Avatar and Avatar Optimizer modifications get reflected / in-house jiggle-bone simulation / animate the avatar via webcam + face tracking (VRCFT and Perfect Sync compatible) / Spout output that feeds the avatar into OBS Studio as a stream source. The whole thing is built so you can confirm an avatar's appearance, animate it, and stream it without ever opening Unity Editor — perfect for pre-stream checks, pre-photo verification, or just running an avatar mascot on your desktop.

The distribution model is the genuinely interesting part: a public beta that's free until May 31, 2026, then becomes paid afterward. It's a time-bounded freemium strategy — get the tool into modders' workflows broadly while it's free, then attach a price once the workflow is established. Compared to January's #5 Zerukana Board ("free version with kanji input + paid version with deeper features"), this is the same freemium philosophy split along a different axis: time, not feature tier. Two coexisting blueprints for how a tool author can use Booth as a free-distribution onramp before moving to monetization.

#3: ChichiwoMore! / Masakaniya

A Unity editor extension that lets you reshape an avatar's body using sliders alone. Built to feel like a character creator's body-edit screen, with head, neck, chest, butt, thighs, calves, arms, and legs each individually scalable. Chest editing alone gets seven axes — size, XYZ scale, XYZ rotation, and spacing.

The preset system is genuinely useful here: one-click switching between "older-sister figure," "glamorous figure," "muchimuchi (curvy)," "SD chibi proportions," "loli-glamorous," and "muchimuchi". There's also a feature that copies your final scale values to outfits using MA Merge Armature with a single click — directly removing the constant "now I have to resize the outfit too" friction modders deal with when swapping clothes.

The verified avatar list covers Milltina, Eku, Ichigo, Shinano, Ramune, Plum, Kumari, Hikarun, Maon, Kipfel, Ruchika, Riru, Kazaris, and Mayo (14 avatars) with the listing noting any Humanoid rig works in principle. Five updates inside February (v1 on Feb 23 → v5 on Mar 3), including the "loli-glamorous" and "muchimuchi" presets and a fix for joint distortion at extreme scale values. At ¥500, paired with Masakaniya's same-month "Punipple" release, two body / blendshape modding tools shipped from the same creator inside February — one of the three creator-concentration patterns of the month.

#4: Fisheye Lens Gimmick / Mujimuji Shouten

An in-VRChat photo gimmick that distorts your camera into a fisheye view. Free — the second free release in the Top 10 — with VR-mode operation flow that lets you hold the camera, fix it in space, and adjust its angle all from inside VR.

The feature surface is much bigger than just fisheye distortion: a menu opens up FOV, lens distortion, vignette, exposure, saturation, contrast, and glitch noise as in-game post-processing — making it a self-contained photo module that runs entirely inside VRChat. There are also grid-line overlays for composition and gesture controls for camera lock and shutter. The prefab ships in three quality grades — standard (CamRenderTexture 23.7MB), high-quality (94.9MB), and ultra-high-quality (126.6MB) — leaving the weight-vs-quality tradeoff in the photographer's hands.

The most notable engineering work is the v1.2 Expressions Parameter overhaul: 111 bits → 64 bits, with the lightweight prefab going 52 → 32 bits. Camera gimmicks have a long-standing reputation for hogging parameter budget, and getting this much parameter optimization into a free release is what justifies its Top 10 placement as a usable tool, not just a curiosity.

#5: Paint & Pick! Mask Maker / Banbi-no-Choujou

A new release from Banbi-no-Choujou — the creator behind the popular "TexColorAdjuster" gimmick & tool — and a mask-painting tool that finishes the entire mask-creation workflow inside Unity, no external paint software needed. The shop's second pick in the February Top 10, paired with #1 Chimera Hair Master in the same role of cutting the back-and-forth between paint apps and Unity.

Toolset is pen, eraser, blur, and UV-island selection (4 tools), with the major differentiator being direct painting on the Scene view in v1.2 — the modder's permanent "where in the UV is this 3D part?" frustration is solved by letting you reach the texture from either the UV canvas or the Scene viewport. Gradient mask read/write is supported for color shifts and emission detail.

The development origin is interesting: the listing explicitly notes "this tool is a byproduct from working on #1 Chimera Hair Master (CHM)." The CHM full edition includes the VCC distribution of this tool, so you choose between "buy CHM full to get both" or "buy this standalone if you only need mask painting" — a clean cross-bundle between two products from the same creator. ¥300 (¥200 during the GW sale) keeps the entry barrier low. Six updates inside February (v0.9 on Feb 5 → v1.1.1 on Feb 12), with continuous follow-ups bridging the tool to CHM after launch.

#6: BoundBonePro / Ajisai-Hiroba Works

A Unity editor extension that adds jiggling physics to an avatar's belly, butt, thighs, calves, upper arms, and cheeks — without ever opening Blender. A direct hit at the heart of VRChat's jiggle-physics culture. ¥900 (with a free trial available).

The technical core is a custom weight-transfer algorithm called "Weight Stealing" that automatically pulls weights from neighboring bones to blend smoothly into the new ones. The listing explicitly frames it as preventing mesh distortion at joint bends and UV seam tears — the goal being to reproduce the flesh-specific feel of a soft surface bouncing while everything else stays put. The original mesh isn't touched; a new mesh is generated, so reverting is one click away.

What stands out is the near-daily release cadence after launch. From v1.0 (Feb 25) to v2.31.6 (Apr 30) in roughly two months, the changelog stacks weight-paint engine rewrites, PhysBone preset overhauls, costume bone support, multi-language localization, and the "Doppelganger" feature (spawn a clone in front of you to test PhysBone interactions inside Unity). Combined with the same creator's #7 UnityAgent, Ajisai-Hiroba Works placed two picks in the February Top 10 — one of the month's three creator-concentration cases.

#7: UnityAgent / Ajisai-Hiroba Works

A natural-language interface tool that lets you chat with an AI inside Unity Editor to automate avatar modding. Type something like "make the hair blue" or "put on this outfit" in Japanese (or English), and the AI automatically picks the right tool out of 100+ internal tools and runs the Unity operation for you. Shipped free, and the most genuinely new direction in February's Top 10.

The list of supported AI providers is unusually wide: Gemini, OpenAI-compatible APIs (LM Studio, Ollama, etc. for local LLMs), Claude, DeepSeek, Groq, Ollama, xAI Grok, Mistral, Perplexity, GeminiCLI, and ClaudeCLI. The Google AI Studio free tier (Gemini 2.5 Flash recommended) means you can run the whole stack — tool + AI API — for free. The dev separately accepts Ko-fi support as the funding pathway.

The feature side is specifically tuned for VRChat modding: outfit dressing (Modular Avatar compatible) / color editing (HSV adjustment, gradients, partial coloring) / facial expression setup (FaceEmo integration) / PhysBone configuration / on/off toggle creation, all addressable in natural language. Destructive operations (delete, reset, etc.) prompt you for confirmation in the chat first / a global Undo button rolls back all session changes — both safety nets are built in. v0.5 in April moved to open source (github.com/lighfu/unity-agent), establishing a new distribution archetype for mod-support tools: "free + OSS + Ko-fi-supported."

#8: Tsukuyomi-Style Logout Effect / orange3134

A fan-made effect inspired by the virtual world "Tsukuyomi" from the Netflix series "Super Princess Kaguya." A logout-trigger gimmick where pale blue crystal particles burst outward as you exit, evoking the feeling of disconnecting from a sci-fi virtual world. Modular Avatar compatible with a setup-helper script included, PC-only (no Quest support). ¥1,500, and the only IP-themed Top 10 entry of February.

#9: Ghost Preset / Nochasutore

A lilToon preset that turns an avatar into a ghost — semi-transparent, softly glowing, aimed squarely at horror role-play and Halloween-tier photo work. ¥600 (¥300 during the GW sale) + Mask Full Set ¥400 + Preset + Mask Full Set ¥1,000 (¥600 during the sale) as a three-tier configuration.

What's notable here is the range of supported avatars: Chiffon, Chocolat, Lime, Plum, Eku, Milfy, Cornet, Azuki, Clara, Ramune, Manuka, Sio, Rurune, Mizuki, Mamehinata, Kipfel, Wendy, Kuuta, +Head, Menno, Alué, Bokusei, Shinano, Mafuyu, Cian, Rinasciita, Nemesis, ELusion, Marycia, Nagi, Milltina, Lapwing, Pug, Seiran, Mashumero, MUMUS, Miminoco, Ohkami Laran, Munkki, Lucifer, Miserum, Haolan, Felis — 40+ original avatars get dedicated masks shipped in the package. Preset shaders typically demand "make your own mask," which makes this one's stance — "if you own a supported avatar, you're already done" — a deliberate move toward accessibility for newer users, well-positioned for Halloween-time deployment.

Setup requires lilToon (mandatory) plus Light Limit Changer's free version as a prerequisite, so the shader stack is on the heavy side, which is worth flagging. After v1.0 on Feb 13, additional Wendy support and Shinano mask fixes have continued through later months.

#10: EDEN Mesh Studio / edenlabs

A tool that completes mesh editing inside Unity Editor. Without leaving Unity, you can do vertex-level mesh editing, symmetric editing, multi-mesh simultaneous editing, and connected-vertex selection — primarily aimed at fixing outfit clipping (clothing intersection) and creating shape keys for avatar adaptation. ¥1,250 (sale) / ¥1,500 (regular).

The standout feature is "Multi-Selection," which lets you simultaneously select an outer layer and an inner layer (or multiple overlapping outfits) and edit them together. The traditional two-step "move the inner outfit, then move the outer outfit, then check the gap" loop becomes a single edit pass when you can move both at once. "Connected Selection" (selection by connected geometry) is for selecting only vertices that are physically connected to a starting point, useful when you want to grab a single accessory or part without affecting neighbors. "Add Blendshape" lets you save the edit as a shape key, so you can keep the result as an on/off-toggleable correction key rather than a permanent mesh modification.

Designed to pair with the same creator's EDEN Auto Morpher (an outfit auto-conversion tool) — the implied workflow is "Auto Morpher gets you 80% of the way, Mesh Studio does the precise final pass." Supports Unity 6 and Unity 2022.3.22f1, with multilingual documentation (Japanese / Korean / English) maintained on Notion — the distribution stance clearly takes Korean-language modders into account alongside Japanese-language ones.

February 2026 Trends

A look at the aggregate numbers and how the rankings break down by axis, to read the shape of February's gimmick & tool category as a whole.

Indicator	Value
Releases analyzed	77
Average like count	1,412
Median like count	772
Average price	¥498
Median price	¥250
Free release ratio	44% (34 / 77)
Under ¥1,000 ratio	79% (61 / 77)
"Modular Avatar Compatible" tag frequency	30% (23 / 77)
Top 10 mod-support (editor extension) picks	7 (#1 / #3 / #5 / #6 / #7 / #10 + partly #2)
Top 10 photo / staging / transformation picks	3 (#4 fisheye / #8 Tsukuyomi / #9 Ghost)
Top 10 free releases	3 (#2 Avatar Viewer / #4 Fisheye / #7 UnityAgent)

The two things that jump out compared to January: free-release ratio leapt from 27% to 44%, and the monthly release count itself grew from 56 to 77 (about a 38% increase). The free-release shift that began in January materialized in February as both higher volume and a higher free-release ratio across the entire category. Median price dropped from ¥500 to ¥250 — the "broadcast tools widely to lock in workflow adoption" creator strategy is now the clear gravitational center of the distribution, more decisively than in January.

Features: MA support paired with shape-key editing

The biggest signal is MA support at 23 picks (30%) standing alone at the top, followed by shape key 11 / blend shape 8 / particle 7 / Udon 6 / shader 5 / world gimmick 5 / PhysBone Compatible 4 / PhysBone Physics 4 / world fixed 4. Compared to January's "MA 20 + shader 7" mix, February tilts toward "MA + shape key / blend shape editing" as the tool author's primary battleground.

The keyword frequency aggregate has editor extension at 37 picks as the most common term overall, then tool 33 / gimmick 28 / free 26 / MA support 24 / Unity 22 — confirming "Unity editor extensions running on top of Modular Avatar" as the dominant form-factor in February, continuing from January. Tools that target shape keys and blend shapes as their object of editing are visibly thicker this month, and Top 10 reflects it: #1 Chimera Hair Master (mesh deformation exported as BlendShape), #3 ChichiwoMore! (body shape-key editing), #6 BoundBonePro (BlendShape underlying jiggle setup), and #10 EDEN Mesh Studio (Add Blendshape) all incorporate shape-key axes natively.

A representative shape-key-direct release outside the Top 10:

Same-shop second release after the Top 10's #3 ChichiwoMore! — Masakaniya also shipped this BlendShape-generation approach in February:

"Punipple" is a mesh-modding tool + touch gimmick that auto-generates BlendShapes for nipple-show effects subtly visible through clothing. The dedicated editor needs no manual mesh editing and works with most outfit topologies. ¥500 at release. Together with Top 10's #3 ChichiwoMore!, Masakaniya shipped a body-shape-key + blend-shape-generation pair within February — joining Banbi-no-Choujou and Ajisai-Hiroba Works as the third creator-concentration case of the month.

The opposite role — a tool that menu-izes existing BlendShapes — also appeared as a free release:

"BlendShape Gimmick Creator" is a Unity editor extension that converts an avatar's shape keys into VRChat menu entries with one click. Free. Heavy-shape-key avatars become usable without manually authoring an Animator Controller, demonstrating the gimmick & tool category's signature relationship: tool authors making rich avatars more usable.

Supported avatars: Komado + Manuka + Sio as the standard set

Supported-avatar aggregates land at Milltina 4 / Sio 3 / Shinano 3 / Chocolat 3 / Manuka 3 / Lumina 3 / Ichigo 2 / Eku 2 / Kipfel 2 / Kumari 2. Continuing from January, the Komado family (Chocolat, Plum, Chiffon, Lime) plus Milltina, Manuka, Sio, and Shinano sit as the standard set that gimmick & tool authors target first. Lumina entering with 3 picks as a fresh face in the upper distribution is the new movement of February.

A dedicated shape-key extension for a single avatar landed outside the Top 10:

"ADDHARD-Sio Shapekey" is a Sio-exclusive additional shape-key tool that opens up form-detail adjustments not exposed by default. Built for the long-term fans of one specific avatar, with ¥1,200 pricing and 32 product images on the listing. A clear instance of "tool authors filling in the adjustment axes that the avatar author didn't ship," echoing January's Komado Adjuster relationship into February.

A head-pat staging gimmick with broad support across Milltina, Shinano, Rurune, Chocolat, Lime, Manuka, Kipfel, Lumina, Celestia, Ichigo and 14 other avatars:

"Head-Pat Glow Particles -NadeGlow-" is a staging gimmick that releases glowing particles when your head is patted, with four particle variations, designed for photoshoots and casual interactions. ¥500, MA + lilToon compatible. The wide supported-avatar list places it in the "broad compatibility + lightweight effect" bucket — a representative shape on the supported-avatar axis for February.

Pricing: 44% free, ~79% under ¥1,000

Price distribution: 34 free / 10 at ¥1–499 / 17 at ¥500–999 — totalling 61 (79%) under ¥1,000. 11 at ¥1,000–1,999 / 3 at ¥2,000–2,999 / 2 at ¥3,000–4,999 / zero at ¥5,000+. In the Top 10, #8 Tsukuyomi-Style Logout Effect and #10 EDEN Mesh Studio at ¥1,500 are the highest, with everything else falling between ¥0–¥900 — the upper bound dropped further from January's ¥2,500 (Gimmick Tsukuru).

The 34 free releases are the spine of February's lineup, and beyond Top 10 entries #2 / #4 / #7, the variety in the free tier itself was striking.

Beyond #7 UnityAgent (Ajisai-Hiroba Works), other free mod-support tools also landed in February:

"VRCosme | VRChat Retouching Tool" is a VRChat-specific avatar retouching tool for makeup and appearance customization. Free, aimed at the pre-photo finishing-touch use case. Like VRC Avatar Viewer, it goes for the "low entry barrier targeting the photography crowd, no Unity edit pass required" angle, broadening the floor of the gimmick & tool category.

A chibi-conversion tool with broad compatibility across the Komado family and 22 supported avatars, also free:

"Ochibi-chans Converter Tool" is a Unity editor extension that converts a customized avatar into "Ochibi-chans" chibi form with a single click. Non-destructive (it duplicates first, leaving the original intact), free. Verified across Chocolat, Ichigo, Ramune, Lime, Mafuyu, Kikyou, Shinano, Moe, Airi, Chiffon, Kanata, Milfy, Manuka, Eku, Plum, Sio, Rurune, Milltina, Yuugiri, Mao, Konoha, and Kumari (22 avatars) — Komado-centric with broad coverage of major originals.

The ¥1–499 tier (one bucket below the modal price) hosts a heart-effect gimmick with a free-version companion:

"Blow Kiss Gimmick" is an avatar gimmick expressing affection with three variations of heart particles. Configured as free version + paid ¥400 version, MA-compatible with hand-sign linkage and on/off toggling, and a rich color variation set. Released in early February timed against Valentine's, slotting it as the seasonal example of the price tier.

The ¥500–999 tier (the modal bucket) has a universally-applicable doppelganger gimmick as a representative:

"Kawauso-shiki Doppelganger Gimmick" is a universal gimmick that spawns a doppelganger avatar mirroring your own movements, with the ability to output voice from the clone. Designed for solo ASMR and special staging effects, ¥800. Universal rather than avatar-specific, making it easy for modders to graft onto whatever avatar they're already running — a textbook example of the modal price-tier shape.

Indicators that matter to gimmick & tool creators: free-release ratio and monetization models

The gimmick & tool category attracts a mix of tool authors, gimmick creators, and modders. So here's a focused look at the indicators tool authors are likely watching in February's data, with side-by-side comparison against January so the deltas are clear.

Indicator	January	February
Releases analyzed	56	77
Median price	¥500	¥250
Median like count	771	772
Free release ratio	27% (15 / 56)	44% (34 / 77)
Top 10 highest price	¥2,500 (#3 Gimmick Tsukuru)	¥1,500 (#8 / #10)
Top 10 with Modular Avatar required	10 / 10	9 / 10 (#2 Avatar Viewer is an external app)
Top 10 completely free releases	2	3 (#2 / #4 / #7)
Creators with multiple Top 10 picks in the same month	YuichaMart (3 picks) / Toron_ (2 picks counting outside Top 10)	Banbi-no-Choujou (#1 / #5) / Ajisai-Hiroba Works (#6 / #7) / Masakaniya (#3 + 1 outside Top 10)

Tool creator focus points:

Wrap-up

February 2026's gimmick & tool category inherited January's flow and pushed the free-release ratio up another tier. The Top 10 split into 7 mod-support picks + 3 photo/staging picks, leaning toward editor extensions, with two creators each placing two picks: #1 Chimera Hair Master + #5 Mask Tool (Banbi-no-Choujou) in a byproduct → main tool pairing, and #6 BoundBonePro + #7 UnityAgent (Ajisai-Hiroba Works) in a concrete jiggle-physics → abstract AI mod-helper pairing. Two distinct shapes of creator concentration showed up in parallel.

The price distribution went 79% under ¥1,000 / 44% free — relative to January's "82% under ¥1,000 / 27% free," only the free percentage moved up sharply. "Free + later paid" (VRC Avatar Viewer), "free + Ko-fi + OSS" (UnityAgent), "same-creator cross-bundle" (CHM Full Edition with Mask Tool included) — monetization models split into 3–4 distinct patterns, which reads as other tool authors re-thinking "what shape should I distribute in" after January saw a free MIT-licensed avatar-compression tool reach the top of the category. Modular Avatar required for 9 of the Top 10, an AI-driven tool reaching the Top 10, a Unity-and-VRChat-SDK-free standalone app reaching the Top 10 — the foundation layer of the VRChat modding workflow continues to harden in this category, while genuinely new distribution patterns and new technologies showed up in the same month's Top 10. A high-variance month.
