Radiosity Artifacts


I am trying to calculate lighting of a tunnel section with Radiosity. I tried various settings but I am not able to get rid of some weird artifacts (semi-random light spots, see picture).

Does anyone know how to set the Radiosity parameters to make the artifacts disappear?



try Element Filter from radiosity post process
