So right now my game doesn't use textures at all, only vertex colors. However many things would benefit greatly from texturing (e.g. vegetation, clothing). Adding textures means

1. Higher engine complexity
2. Much higher content creation cost

(2) is my major concern.

Anybody got any opinions/advice on this?

@lisyarus I like how Deep Rock Galactic does it: most surfaces are plain but have detail added via a limited number of detail textures (looks like they mainly mod normal, roughness and metallic). It breaks up the uniformity just enough to make it look great when it’s really just plain coloured triangles underneath
@sinbad Interesting, thanks!
