You should mention the used renderer...
-
vray renderer

I know nothing about Vray, but check that you don't have the wall faces reversed. Some renderers can't cope with back faces.

Already checked both normal and reversed. thanks anyway

This is to do with 'subdivs'. There are many settings in VRay which could be tweaked to improve your render. To start click on your light source and under the rollout look for 'Sampling' increase the subdivs from the default is 8. Increase this to 16 and take a test render. The higher you go the longer the render will take.
There are lots of tutorials out there on Google and YouTube that will help you with this.

try increasing the subdivs and samples in the Irradiance map, here:
the values will depend on the scene and will increase rendering time a little bit but try something like
HSph. subdivs to 64
Interp. samples to 40 -
i think the problem i solved.
i set HSph. subdivs to 64 and Interp. samples to 40 and everyrhing rendered ok.
i ll try more renderings and get back -
HSph. subdivs to 64 / Interp. samples to 40
that fixed the problem...
thanx
