Daniel_Voloshkevych 0 Posted December 18, 2021 Hey folks I have set up a particle simulation where I have then attached a pyro sim to it (through the rasterize attributes volumes node)... Also I have imported a few objects where the smoke sim should interact with... Everything is fine, until one point: When I am wanting that the pyro sim should collide with the object (seen on the screenshot), then the smoke is just going through the "wall of dirt" (its just a wall with some grass and dirt... ) I just need the collisions so that I can then export the smoke simulation as a vdb sequence... What I have tried so far: - I have give it more thickness with poly extrude node (also added the collision guide thing to look if everything is fine) - also I have increased the substeps on the smoke sim - I have add a object merge node in the pyroFX node (as seen in the screenshot) - just ignore this one node where I have add the red line... But everything I've tried so far, I got no luck to fix it.. Share this post Link to post Share on other sites

zeyneptopalll 4 Posted December 18, 2021 Did i get your problem right? You wanted the collision to happen properly ? Also according to the what you have sent ,entire thing was used as source and when you are importing dop fields , dop node should be the object instead of the entire network .So i fixed it . I put a regular pyro from scratch and piped your colliison geo into it .It seemed like it worked if i understood your problem right? tank.farm.hipnc Share this post Link to post Share on other sites
