Fix: Unity Shader Graph Keyword Default Value Lost on Material Instance Edit

New material instance: should inherit shader's default false. Instance shows true (the previously-set value).

Reset to default

Material inspector > right-click property > Reset to Default. Restores shader's default.

Or use SetKeyword

Code path; explicit set. Avoids the inspector quirk.

Audit per material

List materials; verify keyword states match expectations.

“Material instances cache. Cache survives shader-level changes.”

If shader defaults don't propagate, the cache is the bug source. Manual reset is the workaround.
