Hello everyone,

I've done this roman toga cloth for a character in Marvelous Designer, then I've imported it in Blender to optimize it, reducing number of polygons, made the Uv's, setting face normals, cleared custom split normals data, recalculating outside, smoothing faces, removed sharp edges and everything possible but I still having this weird effect on it.

All polygons are squared and vertices are merged, all faces are oriented correctly and I really can't figure out what's wrong.

Please is there someone that can help me to solve this issue?
Thank you
