@nathanletwory You wouldn’t believe where i found issue
I used Vector3d.Unset as @fraguada since i didn’t want to deal with procedural ones - “most” time those are cached to temp bitmaps. Although you have mentioned that you use zero ones and i didn’t think it will be such a struggle for newly created rendermaterial.
@nathanletwory
Thank you very much for your time on this and i apologize that i didn’t catched that earlier. I think this topic could be marked as solved
