I also wantd to mention, Chat GPT supposedly now has access to Adobe Photoshop, meaning you could ask it to modify a texture to your liking.
Like say, add metal/electronic/organic details that look like they belong in a Serious Sam game?
And I've read that Claude can prepare 3d model objects, if you ask it, or connect it to Blender?
Meaning you can ask it for any additional model you are needing for your mod, and then request textures for it.
