tagosaku Posted November 22, 2023 Share Posted November 22, 2023 (edited) Hi, I have a question about VDB vel. Normaly when I create a VDB from poly, I don't use 'fill interior', and after processing, somtimes I have to fill out or interpolate velocity inside of object. I tried a VDB_combine, VDB_extrapolate, etc. However, I cannot find a function similar to Fill interior. My guess is that at least there are 2 steps; I have to activate inisde of object then intepolate vel from a object shell. Does anone know others ways to do it? Thanks!

Atom Posted November 23, 2023 Share Posted November 23, 2023 Try dropping down a volume wrangle. You should be able to assign a new value throughout. @vel = set(0,1,0); Another strategy might be to use a points from volume after your box to generate interior points before assigning them velocity. Then rasterize them to generate your VDB. Quote Link to comment Share on other sites More sharing options...
