UV data munted after exporting from studio

[saddleup_andride (saddle)]

As per title, the UV data on my mesh is being absolutely munted after exporting it from studio.

This has been occuring to only this mesh since I first tried many moons ago (probably around a year), i haven’t had this issue with any other meshes. Any ideas?

This is the UV map supplied, and it does work, issues are arising as I need to export the mesh and split it

Turns out it needed to have a texture on it for uv data to be retained
