Problem with textures after importing mesh from 3ds

I know this is probably a silly question but i just dont know ue4 and 3ds that much.
My problem is that whenever i import texture from 3ds and apply texture on part that was edited in 3ds by anything else than extrude, it get’s all messed up.

I would really apprecieate some help.

Here’s what i mean by messed up:

It looks to me like the UV map on the model is not right. UV unwrapping is the process of ‘laying the model flat’ or unwrapping it so the engine knows how to apply a flat texture to a 3d object.

Okay, it was my fault. I didn’t set up UV mapping in 3Ds Max. Strangely in earlier versions of 3Ds i didn’t had this problem.
