Is the problem you showing in the video the shadows on the building popping up? In the .scn file what number do you have for this line? MaxShadowRange=(550.00)
@philrob Your suggestion didn't help. @DJCruicky Your comment helps, though not entirely. Also, by changing that parameter, now the shadow is less dark. For the moment the effect is less annoying because it affects fewer objects. I'll focus on manipulating them to see if I can mitigate those flickers. Thank you for your contributions.
I had in the past also problem with dark shadow on track. Do you know if the object has really different uv maps made ? When I had the problem the uv map B, C, and D were not defined. So for albedo, ao, mr, and normal maps I used the UV_A map and problem resolved! I theory we should bake the uv map on onther uv map. Try this maybe resolve the problem
