RADIANCE RENDERING ARTIFACTS PROBLEM - SEVERE GRAIN IN INDIRECT ILLUMINATION

(correctly posted)

Please can any Radiance users assist with a rendering error on an
architectural illustration project.

Severe grain appears in a Radiance render where indirect illumination
strikes an interior floor, similar to a moir� pattern. Some grain in
Radiance images is easily corrected with PFILT using down-sampling and a
radial blur filter, but the artifacts encountered were too severe for this
to be effective.

Please visit my Internet Site :

to assess images of the problem.
