Obj meshes loading broken

Hi,

I can't use OBJ meshes in the meshes tab, if I load a .tre mesh everything works perfectly,
but objs just don't work regardless of the export settings. (I use Blender to export the meshes)


I'm able to import the meshes, by turning on some settings like triangulation when I export the meshes in Blender, but even then they seem broken (certainly the UVs are broken).
