Importing or using existing UV maps in Rhino

I have imported OBJ file from maya, which has an assigned custom UV map. It shows perfectly on rendered view.
However, when exporting it to VRML2 format - the file comes without the texture.
What should I do?

I think you have to assign the textures again. I made a quick search and it seems that format doesn’t store the texture paths but the uvmapping yes.
