.Obj Texture not showing up after exporting + Solid/Texture Mode Issues.

Alright, so I have a can and want to place it ontop of the counter for a kitchen scene. It should be simple, right?

Here is the scene in “solid mode”

How do I combine the solid mode kitchen with the can in texture mode? Clearly the kitchen looks better in solid mode.

My other issue is that if I modify the can by itself (make it look stepped on, etc.) then if I export it to .obj and then import it into another scene it will NEVER have any textures. I feel like there is a step I’m missing involving UV mapping or something (according to other forums). I can’t figure it out.

Many thanks! These problems are driving my crazy.
