Rendering large images - what's the script?

Rick Eloy · May 18th, 2006

Hey, folks!
I searched all over for this and did not find any answers, so decided to ask myself...
Back in the r3 days, we used a script that would automatically divide a huge image in 4 or more equal pieces so Max could render it. Does anybody know if that script still exists for Max 7 (can't remember the name)? I know I can do it with region or blowup, but since I'm doing like a dozen images, I figured a script would help a lot.

Why not just use the render strip feature in backburner? We are finding it to be quite useful on large images.

The one I am thinking of was region net render.

Render strip in Backburner and BigRender... Right, guys! I'm gonna give those a try and let you know. Thank you for the fast replies!

In Brazil renderer - tiled rendering option may help you, or you can also try "on & increse" the Bitmap pager under preference setting- render.

Not using Brazil, here....
Anyway, I just started to render using backburner. First time I got an error after 50% of the pic was completed. Just trying again.

Hi Rick,

I wrote a script for R3/R4 called Region Net Render. It's now built into MAX as Strip Scanlines in Backburner.

If you do not have enough RAM to render one strip, you may need to look into other alternatives. Maybe you need to just render the strips and assemble them manually.

Hope it helps,

Hi, Alex! Long time, huh?
That's the script I was talking about! It was available on your website, right? Anyway, the backburner option really worked. I mean, sometimes my 1 GB ram is not enough to assemble the image afterwards, but that's not really a problem. About rendering the strips manually, one thing I noticed is that if you try to render simply using region, it won't work. It seems max tries to load the whole scene and then render a part of it, which doesn't help much when it comes to saving memory.
Cheers, guys!

Hi Rick,

This will happen in any case. The entire scene needs to be in memory since you never know what will be reflected/refracted/occluded when rendering. Unless you have a REYES renderer (PRMan, etc), the entire scene will be in RAM.

What you save when rendering a strip is the bitmap memory. The bitmap uses 8 bytes per pixel (64bpp) so a 8Kx6K uses 384M of memory. If you do not use the Bitmap Pager, that has to live in a single block of RAM, which is a lot hard to do considering you're also loading your scene in memory.

Cheers,
