Hallo dear Forum.
Every time I try to map cumulative radiation, the heatmap always shows this “mosaic” pattern.
As can be seen, even when the raster is extremely fine (10 cm), there can be differences of up to 50% in kWh/m² between adjacent sensors.
Do you have any suggestions on how to solve this problem?
Thanks and best regards
Hi @LaFleur,
Are you able to share a sample Grasshopper file with internalized geometry or the Rhino file?
Dear Mikkel,
I added only one surface as the ground and one surface to be analyzed.
I also tried using an ar value different from 0 to activate interpolation between the sensors, but this didn’t help either. As you can see, the issue of a result gap between nearby sensors remains, which prevents uniformity in the final result.
Thank you for your help.

Hi @LaFleur,
You should try to lower -lw to the general rule-of-thumb for rfluxmtx: 1/ad. You can also set it lower, which is suggested by Greg Ward, but it probably depends on the scene. The default in HB-Radiance is 1/(ad*100), which is likely lower than necessary for most scenes.
The ar setting is disabled in rfluxmtx.
