to the devs, i got a max-file with this mesh, if its exported as .fbx it will mess up ue4’s import for uv’s, it totally ignores the uv-scaling. any other program works fine but ue4 in this regard. exporting as obj, importing into 3dsmax again, then exporting as .fbx works.
if a dev can provide me with an email, i will send the maxfile (and fbx) to you so you can perhaps find a bug in your .fbx importing.
