/3/ - 3DCG

trying to replicate the old CRPG / Fallout look
I got a texture from ambientcg, used node wrangler to apply all the PBR stuff but it fucks up in Cycles. only thing I can think of is that I edited the color image in photoshop
besides that, is there a better way to texture besides just mark seams > unwrap > apply seamless PBR textures?
I'm used to doing it that way but I'd rather get some texture variance and grit n' grime, seamless procedural stuff seems quite bland / flat
