RADIANCE RENDERING ARTIFACTS PROBLEM - SEVERE GRAIN IN INDIRECT =
ILLUMINATION

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=E9 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 :
www.daiservices.btinternet.co.uk/Radiance/Radiance_v3_5_UNIX/Render_Tests=
/Radiance_render_grain_error_01.htm
 to assess images of the problem.

Kind regards
