art3mis Posted September 7, 2018 Share Posted September 7, 2018 (edited) Hi Trying to create dynamic haze and smoke effects similar to this After effects plugin, but at render time, NOT in post. Is it simply a matter of creating and caching a smoke sim, and then rendering as a volume? Edited September 7, 2018 by art3mis Quote Link to comment Share on other sites More sharing options...
Stephen Moroz Posted September 7, 2018 Share Posted September 7, 2018 Hey, As far as I know, this would be the best way of doing it, yeah. Just create a big a box around your scene, use a vdbfrompolygons node, then add noise with a volume vop. (You'll probably want to spend some time playing with the noise, layering different noises etc. to try and get a nice result) Then you can just pipe this into a sim, emitting the density only on the first frame and add a velocity field to give the smoke some motion. (Depending on the shot, it might be a good idea to model and animate some proxy geo, and use its velocity to move the smoke about). I'm not sure what your end goal is, but if it can be done in comp, then I'd highly recommend it. Much quicker and stock footage will always look more real for this kind of thing. Plus, getting clean renders of big hazy volumes is going to be costly on your render times. Quote Link to comment Share on other sites More sharing options...
