Slow Shader Compiling

Ive been adding some trees and other materials to my 3d side scroller, but when i add it, the engine takes like 3 hours compile my shaders. Is there a fix for this?

Also wish I had a solution for this.

I don’t understand why adding a handful of trees and/or grass completely ruins the entire engine.

yeah, i even added a character from the marketplace and it froze my entire computer, plus my cpu during the shader compile goes up to 50%
