nassosy123 Posted March 14, 2021 Share Posted March 14, 2021 I'm trying to randomly copy/instance a bunch of objects into a scattered point-cloud using the new "Attribute from pieces" and "Copy to points" nodes. I want to manipulate them in a simple DOPnet sourcing them with "RBD Pack Object" and solving them using the "Rigid Body Solver", but the solver doesn't seem to find the neither the "name" attribute or a compatible geometry. I can't figure out what is wrong with it. Can anyone help? (tried with SOP level RBD solver and it works fine. still i want to use a DOPnet) thanks in advance.

bunker Posted March 14, 2021 Share Posted March 14, 2021 On the bullet solver, in Advanced, set Sleeping Time to zero. Some of the pieces are moving so slowly that they get de-activated over time. For the dopnet part, you need a unique name per pieces, you can create that from the ID s@name="piece_"+itoa(i@id); I attached an example, also adding some initial velocity to the pieces. swarm-02.zip 1 Quote Link to comment Share on other sites More sharing options...
nassosy123 Posted March 15, 2021 Author Share Posted March 15, 2021 thanks for Sleeping Time hint! As for the DOPnet, i opened the file and it still didn't work, Then i deleted and re-created the RBD Packed Object node and everything worked like a charm, even without your modification. (propably a glitch, don't know) thank you for your help. i'm gratefull. Quote Link to comment Share on other sites More sharing options...
