BMixer is an add-on that introduces a layer-based workflow for creating and blending PBR materials natively within Blender. It utilizes a triplanar projection system to apply texture maps without the need for manual UV unwrapping, alongside an advanced engine option designed to mitigate blurry transitions between projected axes.

The tool provides non-destructive layer management similar to standard image editors, allowing for procedural masking using built-in noise controls and selective blending between layers. A dedicated brush mode automates UV and image mask creation, enabling direct painting of layer visibility onto 3D models.

Additional features include automatic PBR texture assignment based on file naming conventions, per-layer transform controls, and integrated anti-tiling solutions such as Voronoi rotation and color variation noise. The add-on supports full PBR channels including emission, displacement, and ambient occlusion, and features an integrated asset manager for browsing local material libraries.
