[Radiance-general]radiance daylight study

[steve michel]

I want to validate a sunpatch study for an existing office space. But my renders don't show shadows correctly. I use Sketchup export with a rif file set to QUALITY=high and other settings set to MEDIUM to rapidly show direct sunlight on workplanes. The modeled space has the correct window openings and surface reflectances. Even when I adjust exposure interactively in X window, I don't see the correct sunpatch/shadows I expect for the location/time sky model (+i). 



my render settings are as follows:

< Scene_1.oct
	rvu -vu 0 0 1 -vf views/Scene_1.vf -ps 1 -pt .04 -dp 2048 -ar 105 -ms 0.24 -ds .1 -dj .65 -dt .05 -dc .75 -dr 3 -sj 1 -st .01 -ab 3 -aa .1 -ad 1536 -as 768 -av 8 8 8 -lr 12 -lw .0005 -R Scene_1.rif -o x11 -pe -4 Scene_1.oct>>

Any help there would be appreciated\\\


regards
Steve
