Finally worked around my export issues, however a new issue is that for some reason the lighting is changing drastically as the model moves through the shot, it’s like the model is passing through different lighting environments and the change over is lagging so much that as you can see at the end the FG just keeps getting brighter for no reason. there aren’t any blue lights in the scene, just the emissive materials that are baked into the lighting from the ceiling.
