View Full Version : Particles not animating in render (maya2008)

Hi all. Having a very odd problem so thought I'd come to the masters for help.

I'm using Maya 2008 and particles to make some rain for my senior project at school. The rain is on it's own render layer and is cached. It renders out fine on any shot that does not have any camera movement. However, one of my scenes has a camera move and on this shot, the rain particles don't animate at all. It sorta gives a bullet-timey like effect. Sorta cool, just not at all what I'm going for.

I've checked everything and nothing is different between one shot and the next, so I'm guessing it has something to do with my camera move. Even stranger, the playback in Maya shows the rain animating properly. It's just when I try and batch render the scene out that the rain stays stationary. I've uploaded some half-res videos so you guys can see what I'm talking about.

proper motion:

no motion:

Kindly ignore the random spotlight in the no motion video. I was testing to see if maybe it had something to do with my layer setup (it doesn't). Is there just some silly render setting I'm missing or is there something I'm doing incorrectly? Any help would be greatly appreciated. If you need the scene file, let me know.

Hi Pikadrew

It seems that the particles haven't cached properly. I tried to replicate your scene based on what you described. I found that just enabling memory caching from the solvers menu will hold the cache for playback in Maya. In order to keep all your particle information, you need to use the "Create Particle Disk Cache" function from the same menu. This will cache your simulation properly and assuming your projects are setup properly, will place those files within you particle directory. Batch rendering after doing that seemed to work perfectly.

Hope this helps
