waltt Posted April 17, 2019 Share Posted April 17, 2019 Might be a stupid question, but is there a way to get impactanalysis data from a bgeo sequence? I created a long sim, client want this exact one, but I didn't add the impactanalysis node to it and now I need to add particles whenever objects hit the ground.. Not sure if it's possible but maybe you guys know a way. I could add points to the groundplane with an attribute transfer, and then use those points to spawn particles from, but maybe there's a better option?

tamagochy Posted April 17, 2019 Share Posted April 17, 2019 You can use intersect with some distance and find position at primitive where collision happen. Quote Link to comment Share on other sites More sharing options...
waltt Posted April 17, 2019 Author Share Posted April 17, 2019 That makes more sense then my solution.. Will ttry this. Thank you!! Quote Link to comment Share on other sites More sharing options...
waltt Posted April 17, 2019 Author Share Posted April 17, 2019 Another problem surfaces.. with the intersection analysis I create points, but i want these to dissapear after 1 second, otherwise the particles will keep spawning from these points.. I initially solved this with the particle sop, by setting a life expectance and turning on 'don't reuse points', but this also stops newer particles to spawn from later collisions. Adding age to points and deleting points based on age doesn't seem to be an easy task.. I attached my test file. particles_from_intersection3.hiplc Quote Link to comment Share on other sites More sharing options...
waltt Posted April 18, 2019 Author Share Posted April 18, 2019 Got it working by creating an age attribute and increasing the value of age every frame with a sop solver. Post by mart1jn in this thread helped alot. Thanks! Quote Link to comment Share on other sites More sharing options...
