I have been trying to make a new theme, to go with a specific map I have been working on. I have been making 4k textures, and everything has been going well enough, until it came time to add in Cliff and Sand normals. it keeps giving me the same error, " Something went wrong processing textures" I have tried changing the resolution of the .png file, the bit depth, loading skylines in -noWorkshop mode, even tried saving as .jpeg always the same (un-informative) error. the Normals were generated using https://cpetry.github.io/NormalMap-Online/ from my cliff and sand textures.
