Shader Ops
Will this break my materials?
The addon modifies only what you tell it to. Use the Select Targets operation first to preview exactly which nodes or materials will be affected before running any destructive operation. And remember — Ctrl+Z is always there.
Does this work with Node Groups?
Yes — check the "Traverse Node Groups" option in Stage 1. This makes the addon recursively enter every ShaderNodeGroup to find and modify nodes inside them. Without it, only top-level nodes are affected.
Can I undo operations?
Yes. Every operation registers with Blender's undo system. Press Ctrl+Z immediately after execution to revert all changes. Even batch operations that affect hundreds of materials are undone in a single step.
