I’m sorry I ask such questions every time I come,
But I really can’t solve it.
Sometimes gh editing works, but sometimes it doesn’t. Can someone suggest me what went wrong? I tried changing the uv direction of the surface, and it was still useless.
Your target surface has a curvy portion of very uneven u&v surface domain whereas the flattened surface does not.
Rebuild your target surface would help to solve your problem.
