Does it write to the depth buffer in the shader settings? Are you sure you're looking through the main camera? How does your node tree look?

Ah, hehe, I missed that too :)

Do you get the same issue if they are not marked as static?
Also, are you running deferred or forward rendering, and does switching it make it better/worse?

Are you using Unity's terrain object? If yes, does it happen if you place grass quads manually?

Yeah, GPU node previews are planned, so this probably won't be fixed until that is implemented :)

You can already make global variables by right-clicking the property node and converting it to global :)

I'm most likely not going to make it customizable, but I could make every slider longer, and add a numerical entry field to them.

Should be simple enough!
