Hi @aliasense ,
Do you mean an high dynamic range video? or a sequence of a lot of EXR images?
Anyway, I don’t think so, as it uses a material with a texture for the background and a cube texture (HDR/EXR) for the sky light as source of lighting, so it will work as sky-light usually works, and as materials usually work. It would need to have a custom blueprint to manage and update every image on every frame/tick. But tell me more, please. Maybe in a future, it can be done.
Best regards
