[Radiance-general] mksource program

[Fitzsimmons, Rob]

 Aha 

I've been using the genbox method - also from Debevec. 

Thanks

Below is what I've always used, taken from the example given by Paul
Debevec. I haven't used a light probe with mkillum yet. I had noticed
that
I needed at least -ab 1 (really INDIRECT=1 in the .rif file) to make a
light probe work. I suppose using mkillum would allow the use of -ab 0
while still lighting up the scene?
