I created a series on mini dirt explosions using particles to drive the force and create its shape, I've cached the particles. I wanted to turn those particles into smoke however with Houdini 17 update, I can't get it to work. I used a object merge to get my particles from my file cache, then applied a pyro source then attri noise to get density temperature and v then used an volume raster attribute to view the outcome. I see it but once I create the dop network, using volume source to get the null I created nothing appears in the dop network but I jump out one level and I can view it. Not sure what I missed or did something wrong.
Hope these images help.
