🍩 In this third part of the Donut Project, we dive into procedural masking workflows in Houdini, exploring:

-The powerful Mask by Feature node
-Shadow-based, directional, and ambient occlusion masks
-Comparison with older workflows using Attribute Transfer, Paint, and Scatter
-Why mask-based workflows are more artistic and optimized
-How to control scatter density based on mask or painted attributes

💡 NOTE:
This lesson builds on concepts from M101–M122. Be sure to complete the full Zero to One series before starting this project!
