Hi! I’ve used RC for years now, but I’ve encountered a problem I can’t resolve:
I have a model of only 166 tris and 60x8K textures. Im trying to make a new unwrap using 2048 texture size, but it fails, giving an error message:
“Cant meet the unwrap requirements, please…” etc.
Unwrap settings:
fixed texel, optimal, 2K -failed
adaptive texel 2K -failed
Maximum textures 2K x500 -completed, but texture quality at 3%, 4x2K textures (this is a strange result…)
Initially, I thought that there were too few polys to make a new unwrap at 2K resolution, so I tried the same unwrap on a 17M version, but with the same result.
I realize that this would create an enormous amount of textures, but I thought I could do that in RC.
I hope someone here might have some ideas
