I am currently looking for ways to export the seamline, so far I've found few solutions, but none of it really work for Keyshot, and most info is quite old.

As far as I know, the seamline is only a normal map applied in CLO and there is no way to export it, unless using the "UV editor" bake texture function, but Keyshot didn't have any shading option, so I wonder is there any way I could apply the seamline into the mesh?

I've also saw a few render from keyshot using clo, and I am pretty sure there's a way to work around it, here's some example from others also using keyshot with Clo

Any comment is appreciated!
