Maximum number (256) of shader global keywords exceeded, keyword Unity

Question

When I try to compile my Unity project, and run it on the Oculus Quest, I get a list of errors:

Maximum number (256) of shader global keywords exceeded, keyword _METALLICSMOOTHNESSRANDOMOFFSET_ON will be ignored.
Maximum number (256) of shader global keywords exceeded, keyword _GRAYSCALE_ON will be ignored.
Maximum number (256) of shader global keywords exceeded, keyword _ISANIMATED_ON will be ignored.
Maximum number (256) of shader global keywords exceeded, keyword _LERPSONAR_ON will be ignored.
Maximum number (256) of shader global keywords exceeded, keyword _TOGGLESWITCH0_ON will be ignored.
Maximum number (256) of shader global keywords exceeded, keyword _INVERTCOLORS_ON will be ignored.
Maximum number (256) of shader global keywords exceeded, keyword _STARTPOINTENABLED_ON will be ignored.

I just updated Unity to the last version: 2020.1.15f1

How can I fix this?

Answer 1

I solved the issue deleting the ShaderCache files.

Just go to the directory

<Your Project Directory>\Library\ShaderCache

• Close Unity
• Delete all files in the directory "ShaderCache"
• Open your project

If that doesnt work buy the tool "Shader Control": https://assetstore.unity.com/packages/vfx/shaders/shader-control-74817
