Animated sprite particles?

[Meowx]

Trying to get a sprite particle system set up, and can't help but think I'm missing something basic here.

 

I can't get the opacity to change over time. It's just constant. I adjust the opacity over time on the timeline, but it does nothing.

 

And is it possible to use an animated format for a sprite? .gif or .mov? Had no luck with .mov, nothing renders.

 

Thanks!

my clouds project has an example of spriticles with opacity animated over time. Look at that.

 

for animated sprites, try a TGA sequence rather than mov.

Hello Meow-

I just did a smoke animation where I got the sprite to fade in and out really nicely... you need to keyframe the 'over time' parameter. (See image)

 

 

AND- Quicktimes can be wonky... use a sequence like jpg or tga or png... tga is prolly the best.

Awesome, ty both!

Must have been messing something up with the timeline window. Works fantastic now. d^_^b

 

I'm actually REALLY happy with the result, here's a quick test render I did. Got exactly the effect I was going for.

particles_test.mov

And it takes almost no time at all to render because they're sprites. Thanks again!!

Hmm, is there a known bug with particles + "on the fly" dynamics simulation? I was doing some test renders and noticed that my dynamics had all but died - their effects were very, very muted. Tried rendering without particles/hair and they were back to normal. Now, easy enough to bypass - just simulate springs first - but is this a known issue?

 

This was also in a "shaded" movie render. I didn't try it with a full quality render.

I seem to recall that we're supposed to simulate springs before rendering now, but back around v10.5 I didnt' have to. None-the-less if you candocument a case of unecpected behavior with particles present make an AMReport of it.
