@jbuckland1984 OK, I just saw saw this so I'm going to respond.
YES.. sort of.. I've had a good strong start to renders and then BAM!!! Either entire top or entire bottom half of pic goes transparent. I mean it literally goes straight line across entire pic/side to side, difference top and bottom.
I thought maybe something like a light was in the way but thats not it. I then moved the camera a bit until it finally decided to render properly. I'm glad its not just me. OH and its happened on just a single figure in a scene too, with nothing else so.. I think it might just be a random glitch with studio.
