They’re moveable/dynamic. It definitely looks to be related to the Lighting Channels. I can’t seem to get it right. I have the ground set to 1, the Key Light has 1 enabled so I can get my shadows showing up behind the character. The character is set to 0 and 2, and the Fill and Rim Lights are set to 2. But having the character on 2 channels causing the flickering to happen.
