Texture mapping scale changes after copy to a different file

Hello Community,

Lately, I’ve been encountering an issue more and more frequently during coordination. Our team often works on a design using multiple Rhino files, and when I try to copy data from one model into another, the material mapping changes drastically. I’ve double-checked all the mapping parameters, and oddly, they appear to be identical across files. The file units are also consistent. Could you share any insights or advice on resolving this?

Hi @rguo2017 ,

My first thought was that the texture may be using WCS and the 3dm file units differ but I know you mentioned they are the same. Can you post that object as it’s own 3dm here please for me to try copying it to a new document? I’m not seeing this issue here in Rhino 8 for Windows.
