Lights not working on face tracking


Hello Zappers.
I have this pair of sunglasses and which looks great on Zaprworks studio but in the experience it comes out black which means the lights are not working. Any ideas what the problem is? The zappar helmet works…


I have some models where I had to add lighting pointing at the face.



Yes I did that. Thanks Steve. I have found out what the problem was I think. My model had two uv maps. So when I removed one then it worked…
I think that was the problem.
