I am having an issue regarding retiming heat and temperature fields to slow motion. I noticed all the examples online using the new retime sop are mostly retiming density. When I retime an explosion though, I get a weird ghosting step as the advected vel steps forward. It gives the sim a sort of jittery, stepping look.
My process/settings is basically…
Sim 15 frames of pyro with substeps cached out to .bgeo.sc with $FF in the output to cache substep data.
Cache goes into retime sop and the range is shifted to 75 frames. So effectively from 1-15 to 1-75.
The retime sop is set to interpolate between input frames, linear interpolation, scale velocities is on, blend mode = advected with interpolate velocity field turned on.
Again… when I isolate the density and the vel field it would appear to slow down just fine. When I try and add the heat and temperature field to slow down I get the harsh stepping.
Thanks!
