hi guys can someone please help me with this..how can i retime my cached pyro sim using time blend and time warp. in my pyro import node inside my timewarp sop i'm retiming from 48 frames to 480 frames. i get this strobing and color change nearly every frame. omg my auto dos node i tried substeppping 2 /4 /and then 10. I took off integer frames in the global animation section, still i get strobing? Can anyone help with this?

So if you want something to slow down form 48 to 480 frames , and you said that you can use substeps , that you only need to write out simulation with substeps.
In your cache node use $FF instead of $F , so for example mySim.$F.bgeo.

hey ginodauri.Thanks for the reply. i've done that as well..writing out the cache files with $FF. It still gives that strobing effect. In the global animation parameter in the box labeled step i've even took the substep down to match the substeps i used in dops for example if i sub stepped by 4 i put 0.25 in the step box after unchecking integer frames. i'm at my wits end here.

Best way: insist sidefx implement something like the ‘reves’ volumes Pixar talked about at siggraph. It looked mouth wateringly good.

In terms of actual solutions right now, I've seen good results by converting volumes to advected particles, retime the particles, then convert back to volume. It's pretty heavy, and still prone to artifacts, but the problem you describe is inherent to slowing down volumes. It's why I want that reves tech so bad…

Thank you Matt I hope they do ..thanks for the link as well
