I have come across this issue many times, while previewing or rendering the video, when the camera gets near to the positions then it starts to create the shadows once been rendered you can clearly see that the shadows creates all of sudden, which kills the whole scene, i wonder why that happens is it because of the rectangular light evenly created for the scene or any setting changes please advise how to get rid of that, please see below images to understand the problem
Hey @yaz_1 , thank you very much for your inquiry.
In this case, you can gladly send me the scene at hand for further troubleshooting when it comes to these behaviors - what I can also advice you do, is to instead of using a rectangle light → Use an emissive surface instead which covers the area the rectangle light would cover instead. For this specific purpose this should be working better.
Let me know in case you require any help with that what so ever.
