I've gotten it on a few occations. Not sure but I think your lightset needs to start with at least one spot (see how it converted) and at least 1 virgin (lol) figure that has not had skins switched out in the matroom >before< you hit the shader. That I found will pull an error. Glad you picked this up! It is hard to go back once you've used it. face_off is off for a few days
