hi_dini Posted June 11, 2020 Share Posted June 11, 2020 Hi I'm making vellum simulation which is advected by volume. and I wanted to change the color of vellum sim into velocity color. But, as you see, in any voxel of boundary box of smoke has few of density and velocity so they have changed even where I don't want to change the color. I just thought if i could cut of all of black voxel in smoke boundary box It wouldn't happen. or, If I can use density data of smoke sim, I can multiply it into my vellum pointwrangle node so If It has low density value, color has not changed. How can I fix this ?? Sorry for my poor English and hope you help me :)) Thank you Quote Link to comment Share on other sites More sharing options...
tamagochy Posted June 11, 2020 Share Posted June 11, 2020 Read about volumesample vex function in help. It's what you need. Quote Link to comment Share on other sites More sharing options...
macj89 Posted June 13, 2020 Share Posted June 13, 2020 Also, as a fast patch, what i would do is making a particle sim advected by that smoke and there u can do whatever attribute transfer from the particles to the geo, since the particle will follow exactly the same movement as the pyro sim.
