I hope I can make this understandable enough for someone to help out.
I have a 2d image that I have preformed a live trace on in Adobe Illustrator. I have saved it and opened the file in Cinema 4d. When it opens any color information that was there is gone leaving only the wireframe to look at.
I am taking the paths of my image and combining them by selecting them all then right clicking and selecting connect+delete. Then I am preforming an Extrude Nurbs while holding alt+command.
To this point everything looks ok, however, when I try to add materials (just using simple colors) it will not allow me to add them to the image/object. The cursor is the red circle with the slash across it.
I have tried to add the materials prior to extruding also with the same results.
