[Radiance-general] Re: Adding the sun to image based lightingenvironment

[Santiago Torres]

Hi,
 
I think Lars is right, the problem is probably the sphere. Usually, when you define an IBL sky it's better to use a source object instead of a sphere (just like when you define a normal sky with gensky). That is probably also why adding the sun source is not making any difference, if you are measuring from inside the sphere (the source is outside).
You can try:
env_glow source sphereenv
0
0
4 0 1 0 180   <--- (replace with appropriate vector for the chrome ball orientation, and angle covered)
Does this make sense, or am I missing something?
Regards,
 
Santiago

Hi Lars,
Yes - have tried both - and no difference. I get however an oconv warning that my srcs.rad file is empty. The experience I have with this warning is that it is related to a missing material description, which in this case is included in the Environment.rad.


oconv Environment.rad > iblmksource.oct

mksource -a 0.5 iblmksource.oct > srcs.rad

oconv -i iblmksource.oct srcs.rad > ibl1.oct

Does this pass oconv without error messages? I think you just need to
remove everything in the second line except the zero here, so it becomes

lum_sun source sun
0
0
4 0.6410 0.5537 -0.5315 0.5323

Cheers, Lars.
