Unity displays millions of lines of shader source in Editor log when the Shader Compiler crashes during builds

Graphics - General



Priority: 3Not yet prioritized for a release


Severity: 3Secondary functionality broken

During builds for PS4 and PC, if the Shader Compiler fails, the entire shader source is output into the build log for each variant that failed to compile. This quickly creates bloated logs (biggest reported being 1.77 GB).

Resolution Note:

Now printing the shader source to editor log only in debug builds. Instead printing some more useful info (shader/pass name, keywords, etc) in case of shader compiler failure.
