Textures seen through issue

Imported a 3D model from blender. There are colliding parts so there are some parts of one object inside other.

The issue is that I see textures if the inside objects not the outside one, as if the inside one have the priority.

Did anyone face this issue? How did you solve this?

Found solution myself.

It happen that an object made out of cylinder had textures on the inside surface (and I have no clue why blender decided that it is a very good idea).
