Cats Blender Plugin v0.19.0 for Blender – The Ultimate All-in-One Avatar & Model Optimizer

Versions:  v0.19.0

File Size: 2.05 MB

Download Cats Blender Plugin v0.19.0 for Blender on Windows and Mac, the industry-standard toolkit designed to streamline the preparation, optimization, and fixing of 3D avatars (specifically for VRChat, Unity, and MMD). With automated bone merging, shape key management, mesh cleanup, and one-click Unity export, Cats transforms how creators prepare models for real-time engines, eliminating hours of manual rigging fixes and topology errors.

Key Features of Cats v0.19.0:

Automated Bone Merging: Instantly merges duplicate or conflicting bones (common in MMD imports) to ensure perfect compatibility with Unity and humanoid rigs without manual weight painting

Advanced Shape Key Tools: Merge similar shape keys, remove zero-impact keys, fix inverted shapes, and create custom shape key mixes for complex facial expressions with a single click

Mesh Optimization & Cleanup: Automatically removes doubles, fixes non-manifold geometry, separates meshes by material, and applies safe decimation to reduce poly counts while preserving visual fidelity

Rig Fixing & Retargeting: Repairs broken armatures, corrects bone rolls, and offers tools to retarget animations between different skeleton standards (MMD to Unity Humanoid)

Material & Texture Handling: Converts complex MMD shaders to standard Unity-compatible materials, merges texture atlases to reduce draw calls, and fixes UV island issues automatically

VRChat Specific Tools: Includes specialized features for creating PhysBones, setting up eye tracking, configuring lip sync shapes, and validating avatar parameters for SDK3

Batch Processing: Apply optimization steps to multiple avatars or variations simultaneously, perfect for creators managing large libraries of characters

Enhanced Stability v0.19.0: Improved handling of complex MMD PMX files, better support for Blender 4.x bone collections, fixed crashes during large mesh decimation, and updated Unity export presets for URP/HDRP

Cross-Platform Support: Works flawlessly on both Windows and Mac systems including Apple Silicon M1/M2/M3 chips

Perfect For:

VRChat creators uploading custom avatars with optimized performance and full feature sets

MMD (MikuMikuDance) users importing models into Blender for conversion to modern formats

Indie game developers needing to quickly clean up and optimize character assets for Unity/Unreal

Animators fixing broken rigs and shape keys on downloaded or commissioned models

Anyone struggling with the tedious manual process of preparing avatars for real-time engines

System Requirements:

Blender 3.6, 4.0, 4.1, 4.2, 4.3+ (Latest LTS recommended)

Windows 10/11 (64-bit) or macOS 10.15+

8GB RAM minimum (16GB+ recommended for high-poly MMD models)

Python 3.10+ (Included with modern Blender versions)

Installation:
Open Blender and go to Edit > Preferences > Add-ons:

Click “Install…” and select the downloaded .zip file for Cats Blender Plugin

Enable the checkbox next to “3D View: Cats”

Access via the 3D Viewport Sidebar (N-panel) > CATS Tab (usually located at the top of the panel)

Note: Version 0.19.0 includes critical updates for the latest VRChat SDK requirements, improved accuracy in automatic weight transfer when merging meshes, and a new “Safe Mode” for decimation that prioritizes preserving facial features and joint deformation areas.

A tool designed to shorten steps needed to import and optimize models into VRChat. Compatible models are: MMD, XNALara, Mixamo, Source Engine, Unreal Engine, DAZ/Poser, Blender Rigify, Sims 2, Motion Builder, 3DS Max and potentially more

With Cats it takes only a few minutes to upload your model into VRChat. All the hours long processes of fixing your models are compressed into a few functions!

So if you enjoy how this plugin saves you countless hours of work consider supporting us through Patreon. There are a lot of perks like having your name inside the plugin!
