Rendering irradiance map on multiple machines (not distributed rendering)

[Fredrik Averpil]

It *is* scriptable (insofar as you can modify it with a pre-render script). However we can't make it support expressions.

I export a .vrscene so I can't use pre-render MEL... but now when I think about it ... can I use the post translate python feature for this?

Nope; there are too many options already

That's true

#### is dangerous as it is a valid file/directory name character and believe or not, people use it in folder names (we've gotten into trouble for that reason before).

Holy moly... oh well, I can totally see people doing that actually.

That leaves %0nd as a possible variant, but again, it is somewhat ambiguous as to what should happen. I think it would work best if %0nd is replaced with the first frame that gets rendered in the particular rendering process. For example, if you put something like imap_%003d.vrmap and render frames 50 through 70, you'll get one irradiance map file named imap_050.vrmap that contains the baked map for the entire sequence (frames 50 through 70). Would that work for you?

Sure!
That would be awesome!

EDIT:
Just to double-check: That means I could just set the autosave filepath to ".../path/to/renderjob/vrmaps/imap.%04d.vrmap", and depending on the framerange of each "chunk", the resulting vrmap file will have a unique name on disk, right?

So:
imap.%04d.vrmap -> imap.0001.vrmap for framerange 1-100
imap.%04d.vrmap -> imap.0101.vrmap for framerange 101-200
...right?

Hi again,

I just wanted to check back in and see if there are any plans on implementing this automatic translation of the occurance of %0nd in the vrmap filepath -- or if I should expect this feature not to show up anytime soon.

Will try to put it in the nightlies for next week.

Many thanks!
