Rhino render randomly messes up the lighting! Please help

Hello everyone,

I need your help. I am creating a turn table animation with rhino render.
But the trouble is that randomly the render starts with the lighting incorrect.

Below render is an example of a frame rendered proper and ok.

Below are examples where the render lighting is messed up, even though all the settings are the same…



Has anyone else faced this problem?
Does anyone know a solution?

Thanks.
Brian.

hi @Brian_J_Yook can you share the file? If it is confidential, you can upload it here.
If the same issue happens with just a few cubes then that’s even better to send.
