View Full Version : particle cache/rendering issues

07 July 2003, 10:30 PM
greetings everyone,

ok, im rendering two seperate layers here, one w/ a character, the other w/ blood spurts.
i create a particle cache, batch render the character at 300 frames, & all is good.
BUT, when I batch render the blobby particles, It'll only render 196 of the 300 frames, & then tell me "rendering completed."
the first time i thought it was just a freak accident in the render globals, but now it's obvious something's obstructing the dynamics rendering, & i suspect it to be the particle cache
(never had this problem before, but i usually don't have enough sprites to create a cache)

please help.

Did you try rendering let's say frame 197 from the command line via the batch render and look for some error messages - or are errors listed in the logs?

i'm not sure how to render via command line. undoubtedly it's a very simple expression but i've never sought it out, always just used batch render.
anyway, no error from batch render of single frame.
no discernable errors in the logs. it just stopped at frame 196 for some odd reason.
i can tell you that i just rendered 300 frames of particles & geometry in the same pass & it worked fine.
i know these types of things don't always have discernable solutions, but i was just crying out in desperation! thanks for the reponse.
i've also heard about rendering from the command prompt (correct?) what types of situations would command line/propt rendering be called for?

try to start rendering one frame past the frame that it stops on (199 in this case).

as for rendering in a shell
open a shell (use the run short cut in the windows menu just write cmd )
navigate to the scenes folder of the scene you want to render.

The syntax for rendering should look some thing like this.

render -s 199 -e 300 -rd c:\render_dir_path sceneName.mb

-s = start
-e = end
-rd = render directory

To render the bad frame sometimes rendering it in a window will let you complete it. Other wise delete everything in the scene that is not part of the particle system save it as something else and render that. Not having to calculate all of the other stuff in your scene may allow Maya to get by the stumbling block.

Good Luck.
