Fix: Unity Shader Keyword System Blocks Build With 'Too Many Keywords'

Project grows; build fails: Maximum number of shader keywords exceeded.

Audit keyword count

Window > Analysis > Build Report > Shader Keywords. Lists every keyword; consolidate similar ones.

Use local keywords

Local keywords don't count against global pool. Convert global-to-local for shader-specific keywords.

Multi-compile vs shader_feature

multi_compile generates variants for build; shader_feature requires preprocessor define. Switch where appropriate.

“Keyword pool is finite. Pool exhaustion is a configuration cleanup task.”

Track keyword count as a project metric. Sudden growth surfaces accidentally-added keywords.
