Smoke Retime flickering Jan. 15, 2020, 6:01 a.m.
Very helpful, just fixed up a shot I am working on with this.
…Half frame offsets are in a sense the most difficult to interpolate (the minimum distance between input frames is maximized right in the middle). So your settings are giving the retimer a really difficult job here–it constantly switches between the “nicest” (integer frame) and “worst” (half frame) volumes. If you change your start frame to 1.25 instead, then you'll get a fairly consistent level of blurring throughout (since it'll compute frames 1.25, 1.75, 2.25, etc.), and the flickering should be eliminated.
Volume retime strobing or stuttering problem Nov. 25, 2019, 6:33 a.m.
An additional follow up, I was specifically getting this with Redshift. I reported the bug and it is hopefully fixed for the next release…
I think that I’ve found why this happens, and it is related to the fact that in your scene the velocity grids are the first ones in the primitives list and they have a variable grid resolution among the frames. I’ve have added a fix for this issue to the next Redshift 3.0 build that hopefully should resolve this problem.
Thanks for reporting this issue!
