lflores Posted October 5, 2013 Share Posted October 5, 2013 I was experimenting with having a gas sim on a moving object. The emitter translated with the object and left a trail of mist. Since the emitter was moving, the voxels at the emitter always looked very crude and low rez, no matter how many substeps, and no matter the resolution. By the time the smoke got about 20 frames of dynamics, it started to get some detail and look good, but this was never the case at the emitter. I got much better results by just running the sim in world space (not animated) and blowing the sim back with a wind. Is there a way to specify that a gas simulation grid is actually moving with a given velocity? Or are all grids implicitly static? That way I could have the simulation grid parented to the object, but DOPs would know its moving in world space and do the appropriate dynamics.
