I am trying to do some Moon renders using NASA's CGI Moon Kit: https://svs.gsfc.nasa.gov/4720
Said kit has super high-res color and displacement textures (27000x13000), but this is what I'm getting up close:
Is there a way to smooth it out? Even though a 27k displacement texture which weighs 1,06 GB shouldn't even look like that in the first place...
Shade Smooth is (of course) enabled. Auto Smooth is off. I tried adding a bunch of Subdivision Surface modifiers, but they didn't help at all. Someone said I should use Adaptive Subdivision, but I couldn't find it in the Subdivision Surface modifier panel. I also tried plugging the same displacement texture in the Normal input of the Principled BSDF through a Bump node, but the result was even worse.
Please help me!
