FUME Post Retime Fickering.

#1

Hey All,

I just completed a great simulation, did a wavelet at 2, then post processed to retime it slower by 50%. However after rendering I get a brightness flickering every other frame…anyone know what may be happening?

Thanks!

You just interpolated 100% of your frames to create 100% more frames. You did it in right order but slowing down is iffy especially by half (retime is much better at speeding up or minor slowdown), you just made up a frame for every frame with data from its nearest neighbor and that is only as accurate as the algorithm. I would try retiming in comp instead if you want to slow down that much.

Hey Johhny, thanks for the response. I haven’t done any testing, but I thought reduction of speed in post by 50% wasn’t too big a deal as I recently saw an FXPhd tutorial by Alan McKay and he selected a frame range and post processed by a setting of .2 !

I didn’t see a clear version of the render though and his might have been flickering too!..:slight_smile:

I’ll set it higher and see what happens…

try to turn of illumination map, fumefx lights properties, the rendering takes longer but maybe it helps

Also if you have Afterburn installed by any chance make sure you use the new AfterFlics license server. Ther is a reported flickering issue related to the old license server.

Nah, it is an Illumination+Retime slower issue. I can’t yet test it on the latest build due to a bug.

EDIT: Illumination is not really the right word, it is more like the emission from fire that is the issue.

I totally agree with John but its not just emission from fire + Retime issue…I got it with just smoke too. What I found is you get it when you have scattering on with bit of value to smoke. The AFlics license bug fix is not the answer here. I ran up with this very same thing recently and am on the latest release.
