Yeah Bantha, thats unfortunately very true. I contiounously stumble across this. HOwever, i found another problem to fix: When importing the standard shading rate on an object is 0,2 which overrides the render settings. So when setting this to a lower rate, the errors where completly gone.

Thanks all for your help.
