Is there a way in houdini to asign diferent textures to the inner and the outer side of an object?

For example, I created a really big sphere to be a galaxy enviroment of my planet. I want to assign a Stars texture to the inner part of the sphere so if I am inside the sphere I can see a stars background but if my camera gets out I want other things to ve viewed, even a tranaparent texture to see what is inside the sphere without using wireframe mode.

Is there any way to assign a texture to only a side of an object?

Thanks

You can use the TwoSided VOP:

Ooops, VEX operators, i'm too novice to this… but I will try

Thanks!!
