IN poser pro 2012 sr3 Dimension3d render firefly script, I see a precalulation scale box. What is this for?

The IDL precalc gets bigger based on image size. As a result, your memory consumption can be rather huge if you are doing something in the multi-megapixel range. Some people were running out of memory very often.

To help with that, you can use that to change the IDL precalc as if you were doing a smaller image. For example, if have a 2K by 2K image but you set the precalc scale to .5, the precalc will act like it's a 1K by 1K image, and save you 3/4 of the RAM it normally uses.

The downside is detail/resolution may be lost (not that important for IDL) and artifacts will be bigger.

Everything in CG is some kind of nasty trade-off.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)

Crikey! That's brilliant!

Is this kind of stuff documented anywhere? I haven't seen it in the manual.

(Though I confess I haven't looked at the SR3 manual yet...)

Sorry I can't say - I don't read the Poser manuals. (except to point out that other people should read them, and then I show them the part they should have read)

PoserPython Methods Manual pages 311 and 322, GIPassScale() and SetGIPassScale(). It's not currently exposed in the GUI, but Dimension3D is taking advantage of it.
