[Radiance-general] system - out of memory in makevsrc

[Greg Ward]

Hi Giovanni,

I see nothing wrong with your parameter settings, so it may have  
something to do with your scene description.  You must be using the  
"mirror" primitive in order to generate your virtual sources -- is  
this correct?  How many surfaces do you have using the mirror type?   
Is it a large surface tessellated into many smaller polygons?  The  
fewer surfaces you hand to the virtual source calculation, the better  
it will do.  I've never encountered this error before.
