Hi Catttdaddy,
Do you mean the moon is just mostly bright white without the crater detail of the texture? Do you have any glow or similar components on your camera that might be blowing out the moon brightness? It might be an issue of needing tonemapping on your scene camera as well, which i always recommend people use in Unity in general, not just with Tenkoku.
Are you using Gamma or Linear rendering in your project?
If you don't have any camera effects, and it's still happening, definitely let me know.
