I have a 3D model i downloaded from net as free. It is a 3D cube and it is in .obj format. In Xcode it is shown as one object and it have different materials inside it. Now my question is that can i detect touch on materials as i can detect on Nodes?

If not then is Designed Model needed to be different nodes of things making up one single object?

I have no idea of designing a 3D object. Need any idea for Development or Design end.
