I am working with Character Creator 4 Game Base characters in Unity with URP (2021.3.8) with CC Importer 1.3.7. Has anyone gotten this error about problems with the Cornea Shader?

Shader error in 'Shader Graphs/RL_CorneaShaderBasic_Baked_URP': maximum ps_5_0 sampler register index (16) exceeded at line 3808 (on gles3)

If anyone has ideas of solutions, I would love the help!

Thank you!
