I always save the scene in studio once completed (which I had then I rendered the bare scene you commented on) This morning upon merging the character I had saved to work in Reality, I select the surefaces of the clothing I had set to matte it was all glossy again then when I re adjusted & ran a test render, I noticed all my convert to light were not lit up I look in the light groups and see them all AWOL then I check the metarials I had converted most of them had reverted to full glossy as well. I dont get it...
