it just disappears, and the funny thing is when i tried to do the shades top to smart prop to the shade, same thing happened. Then i figured out that i can just import the obj files of the shade and the top and then export them as one file without hurting the lamps uv map. which is a good thing. although i cant do the same with the figure floor lamp and the shade...so im kinda stuck and dont know how to fix this problem im having.
