CAD applications in general don't transfer textures/materials well, or at all.

I wish there were standardized procedural textures and texture mapping, but it would probably have to come with a new 3D cad format. I don't know if there is "room" in any of the current formats like IGS, STP, SAT etc. to incorporate this.

DarkTree http://www.darksim.com/html/products.html http://www.darksim.com/Repository/index.html started to do this with procedural textures and poly modelers but unfortunately it never really caught on. I think it was a very good idea.


Michael,

I thought OBJ had support for nurbs surfaces (or at least spline surfaces) but I have never come across any applications that write nurbs/spline surfaces to OBJ files.

Do you have any idea why developers don't use this function?
