Material Problems

[RatedR]

Hello,
i created a simple Background in Max and have put standard materials on the boxes.

When i export it to Octane i get this strange radial shadows on everything (see picture)

Does anyone know whats causing this problem?

Looks like a scale problem.
Octane units are in meters. Try to check the scene scale.

I have it also set to meters in Max so that cant be the problem

EDIT: I downscaled the whole object now and it works perfectly, thanks for your fast help
