Hi,
I have a question about MegaPov XRS: When I use 2 or more CPU to render a
scene, How is the work divided? The image is divided in 'n' sections
(n=number of CPU) or
all CPU work to the same pixel?

I ask this because I've tried to render a scene (using MegaPOV without XRS)
in 2 sections and after that I merge the 2 sections in photoshop and the
light in the first section is different from the light intensity in the
second section.
This only happens when I use radiosity.

Hi JSR, great observation! The bottom line is that Jaime Vives Piqures found
a way to (for most practical purposes) eliminate the appearance of those
"tiling artifacts". The threads below should be of interest to you. Let me
know if you need any help.

Hi Joel, I'm sorry I forgot to answer your first question. Yes, MegaPOV XRS
splits the scene into n sections ("tiles") and each CPU renders one tile.
How are you doing with MegaPOV XRS?

Regards,
George
