Hi.
I’m studying the distribution of daylight in a model, and I’ve done som PIT calculations with an overcast sky. But the spread of daylight inside, doesn’t seem to be just right.
Running the simulation with RadPar detail level 0 or 1, seems to have no internal reflections.
Running the simulation with detail level 2, gives smooth visualizations, but the internal spread is not physically correct. e.g. the calculation seems to not include the incidence angle of the glazing, as there is light in the corner itself.
I tried running it with other radiance parameters:
-aa .1 -ab 7 -ad 2048 -ar 0 -as 1024 -dr 3 -ds .15 -lr 8 -lw .000001 -dc .75 -dp 512 -dt .05 -st .15 -dj .7
This takes a looooong time, and the results are then quite spotty, but the internal spread seems to be more correct.
There is also something happening outside, as the window sills have uneven lux levels:
This happens also with detail level 2:
The file is also attached.

I’ve also rendered the same geometry, using Climate Studio, and this goes much faster and looks better:
But would prefer to use LBT, for various reasons, among these that one can produce several PITViews in a batch and the connection to pollination cloud.
Any ideas as to what is happening?
