system - out of memory in makevsrc

Dear List,

I am trying to simulate a scene with a number of specular reflections
into a cavity.

I was trying to use the trans material to this goal, as I want to have
specular reflections combined with some light transmission.

After having the simulation running for 17hours I received this message

rpict: system - out of memory in makevsrc

these are my rendering parameters

-dp 2048 -ar 104 -ms 0.26 -ds .2 -dt .05 -dc .75 -dr 3 -sj 1 -st .01 -ab
4 -af myscene.amb -aa .1 -ad 1536 -as 768 -av 0.01 0.01 0.01 -lr 12 -lw
.0005

Would some change to those parameters allow me to run the simulation or
too many specular reflections are bound to cause problems?

Thanks for your help in advance,

Best,

Giovanni

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.
