I have created a simple model in SketchUp and exportet it (Collada .dae format). Importet to Unity everything went fine and looks as it should (after some experimenting with the material shaders) except for 2 textures (see images)
SketchUp (intended) big- Unity small
I checked the material that got imported that Unity uses and their texture is just fine
I tried messing with the tile size of the material but that only changed the colour. (as if only a pixel of the texture is on the material or something like that)
Now i don’t know any further.
