Unity free assets
I'm trying to export a standardasset's Water4Advanced that I edited myself and give it to another person, but when I export it by a test and import it, it turns pink.
I haven't started Unity yet and I don't know how many times I googled it, so I asked a question.

Shader error in'FX/Water4': failed to open source file:'WaterInclude.cginc' at line 46 (on metal)
