How to edit shader moon texture? (1.21.1 neoforge, Photon Shader)

I found come cool Moon Texture that I wanted to use in minecraft.

I tested that it works fine as resource pack without any shaders, but once I use photon the moon texture no longer works, so is there some way to change that?

I tried the vanilla moon and custom sky under shader options but those dont work either.

(it only changes to either shader moon or vanilla moon)

I would appreciate some help thanks.
