UglyMasks Pro is a shader node group for generating complex masks using Blender's built-in procedural textures. The tool allows you to stack and combine up to five texture layers, choosing from seven preselected generated textures for each layer. With ten available combination methods, you can control the output directly through a compact set of node sliders. Multiple instances of the node group can be linked together to bypass the five-layer limit, enabling highly complex procedural material generation.
