Hi, i want to retime simulated smoke. I got some idea to do it dynamically. I have density and velocity fields. I'm trying to readvect the existing density with existing velocity with more substeps and changing the timescale of advect field microsolver. But i'm weak in microsolvers and can't realize the starting point. So if i import density and vel fields from cached sim, then make other density field and advect by cached vel with some different timescale and more substep, theoratically it sho
