I did add the curvature map that was made with textools.
I like the idea of putting stripes or splotches on it. Most cats I seen have stripes.
I made some changes. Here is the new rendering.
Thank you for telling me about the AO, cavity and curvature maps. And thank you for telling me about textools. Oh, yes I am using only free software. Krita, Blender and Ubuntu.
newmodels no problem,
but u can still improve your textures
heres' an older model of mine on sketchfab, not perfect but should give u an idea
if u look at the albedo and roughness theres' highlights and dirt based on the curvature map and occlusion
and also some handpainted highlights.
keep experimenting, cause textures make up for more than half the look of a low poly model
there is offcourse no 'right' way to do it, and everyone has their own workflow
