texture the inside of a model

A picture would aid to clarify the situation.

Dont imagine the objects in Wings have "inside" and "outside" faces. Concept them as a uniform surface with a single side. Of course you can build a cave in it. For example, you can build a box, smooth it, select some adjacent faces, extrude them into the center of the box etc. This would be the correct way to build a cave. All the "walls" should have some thickness, they cant be just a "zero" thick wall.

It is very common people ask for some way to deal with geometries without thickness. For example, take a cube, select a face, make a "hole" with that face and then the confusion begins. "How can i manipulate the 'inside' faces of this cube?" My answer is: there is no "inside" faces. Wings is a box modelling, the surface must have thickness.

Build your geometries like in real world, ie, keeping their thickness. Forget the idea of have a cube without a face and with an inside faces conjunt and an outside one.

Thanks heaps guys, yeah it makes a lot more sense now. I was able to make my cave in a few minutes after realizing this

I really appreciate the help.
