Transform the way you work in Blender with Mask Canvas. Draw masks directly over your image in the Shader Editor, then combine rectangles, circles, polygons, stars, and custom Pen shapes with Union, Difference, and Intersect.
Adjust the edges with Constant, Linear, or Smooth falloff and feathering. Keep the result editable in a node group, bake the finished mask to a mapped Image Texture, or expose individual shapes as separate outputs for use in your material.
If you work with shader masks, I’d love to hear how this fits into your workflow.
