Hello,
In the attachment I have created an environment.
It is not quite possible to get the wall beautiful (UV mapping / baking?).
Most importantly, the situation in the room does not change, the camera moves from the outside to the inside.
Is this a situation where you can best bake the material to reduce the render time??
Thanks for the help.
PS: For this question I have completely cleaned out the room (in my situation, he is full of stuff).
