PyroFX Tests + Video May 29, 2009, 4:40 p.m.

Hmm…I must be missing something here. I managed to open the spreadsheet, but I don't understand what those settings are referring to. They don't seem to coincide with the settings contained within any of my pyro or pyrosolver nodes…?

*edit* Ahh…I see now. I was using the Billowy Smoke preset, instead of the Flames preset. I guess the only real difference is the shader that's applied…interesting…

Oh…great, thanks for that link. (Not sure how I missed it…) Good to know!

Set Initial State for Fluids? May 28, 2009, 5:50 p.m.

Hmm…ok, so another question. I've decided to break up the 500 frame simulation into two, 250-frame sims.

So far I've cached out the low-res and up res solvers and have them loading in from disk. At obj level, I can scrub around the timeline easily with no problems (even tried closing the file and reopening just to check, and it all works fine).

Following the above-mentioned advice, I added a File node to my AutoDopNetwork, and set it to “Write Files”. When I jump to frame 250, the sim proceeds to cook, and writes out a sim file for every single frame. This isn't the way it's supposed to work, is it? If the low- and up-res solvers are both already cached, why does the network need to re-cook? Shouldn't it just be able to write out a sim file for the specific frame I specify?

Actually, after going back and double-checking, it seems that any time I move the timeline, the network wants to re-cook. If I hit escape, it appears to be reading in the cache files, but there must be something that I've overlooked here. Help…?

I've attached the hipnc file (minus the cache files, obviously), for anyone who'd like to give it a go. Thanks in advance!
