quryo Posted October 26, 2018 Share Posted October 26, 2018 Hey everybody, I'm wondering if there is a way, in DOPs working on regular volumes, to convert a smoke/density to an SDF, similar to what convert VDB does. I found the Gas SDF to Fog node, but did not see an equivalent in the other direction. The only workaround I found is to copy the density to a new field, negate and slightly offset it and then run gasreinitializesdf on that. Mainly, the goal is to get curvature and gradient near the smoke surface. Thank you! Quote Link to comment Share on other sites More sharing options...
3dome Posted October 26, 2018 Share Posted October 26, 2018 i guess you could use a sopsolver and in there do all of the operations you need Quote Link to comment Share on other sites More sharing options...
