Texture Mixer
Texture Mixer
A layer-based texturing toolset for Blender. Automate complex node groups for layer and mask management.
🧡 Support & Links
[!WARNING] Experimental Status: This addon is currently in active development (Alpha). All features, node structures, and workflows are subject to change in future updates. Please use with caution on production files and always keep backups!
🚀 ## Features
- Non-Destructive Layer Stack: Manage your PBR materials using layers instead of messy node webs.
- Single-Channel Painting: Paint Base Color, Metallic, Roughness, and more individually.
- Multi-Channel Painting: Paint Base Color, Metallic, Roughness, and more simultaneously.
- Dynamic Masking: Stack paintable and procedural masks on any layer.
- Export Pipeline: Bake your layers into production-ready texture sets with channel packing.
đź“– ## Usage Overview
- Open N-Panel: After installation, find the Texture Mixer tab in the 3D View Sidebar (N).
- Initialize: Create a new Layer Manager for your active/selected mesh. (Note: This will replace the current material with the TM structure).
- Add Layers: Choose between Paint Layers (manual painting) or Fill Layers (procedural/texture inputs).
- Painting: Enter the custom Multi-Channel mode to affect multiple PBR slots in a single stroke.
- Baking: Use the Export tab to flatten your layers into final maps.

A Note from the Developer
Texture Mixer is my first venture into Blender addon development. Coming from C++ & C# background, I am still navigating the nuances of the Blender Python API.
- Much of the current architecture is the result of heavy trial and error to bridge the gap between pure data processing and Blender’s internal systems.
- You may encounter unpolished performance or "crawler" speeds in certain complex scenarios as I work toward more optimized, buffer-based solutions.
- I appreciate your patience and feedback as I continue to learn and refine the addon!

Texture Mixer is currently in Alpha. While every effort is made to ensure stability, this software is provided "as-is," without warranty of any kind.
- Use at your own risk.

- Always keep backups of your
.blendfiles before initializing Texture Mixer on a production model.

What's New

[0.1.1-alpha] - 2026-02-12
Added
- None (Initial Release).
Fixed
- None (Initial Release).
Changed
- None (Initial Release).
Removed
- Developer debugging tool.
Known Issues
- Layer Performance: Stacking a high number of layers (typically 8+) will significantly degrade viewport performance. This is due to the nature of "live" shader node composition. A completely different workflow with significantly better performance and memory usage is currently in development.
- Viewport Rendering: Viewport textures may occasionally appear black. Frequent saving of the .blend file is recommended to ensure data is packed and refreshed.
- Multi-Channel Painting: 'Smear' and 'Mask' brushes are currently unsupported in Multi-Channel mode.
- Multi-Channel Painting: Painting is currently limited to Solid Colors; texture-based sampling and stencils are planned for a future update.
- Multi-Channel Painting: Pressure-sensitive toggles for Size and Strength are disabled to prevent stability issues during the Alpha phase.
- Multi-Channel Painting: Native Blender 'Stroke' settings are only partially supported due to custom parameter overrides.
- Multi-Channel Painting: Native Blender Undo is not supported. A dedicated, robust undo system is a high-priority feature for the next update.
Very good initiative, still in alpha but very clean interface, I (not alone I guess) was waiting for a true multichannel painting for a while, this one seems very promising, thanks.
