Ah, this is great info, exactly what I was looking for! 16 GB is not much of a
problem -- and even if it was, now I can simply do the math and work it out.
Also the info about the temp file is quite useful. My server has a solid state
disk, so if I can use that for all pov-ray activities, it'll probably save a lot
of time.
I'll give it a try, many thanks for all the useful info!
Stefan.
