isah_voodoo Posted May 4, 2019 Share Posted May 4, 2019 (edited) hello, So I applied the rbd cluster node to my fractured pieces and it works great. However the rbd cluster node creates new names for the pieces it clusters. This all makes sense but when i go to create a constraint network, I get a jumbled mess due to having two different names on the pieces. Is there a way I can fix this so that I can get a clean constraint network. I will attach my file to show you what I mean. Thank you rbd_cluster_constraint_name.hip Edited May 4, 2019 by isah_voodoo Quote Link to comment Share on other sites More sharing options...
Ryan Posted May 5, 2019 Share Posted May 5, 2019 (edited) Your problem was that the RBD Cluster node was generating pieces with the same cluster number that were too far away from each other. I switched the Cluster Type to Group Constraints. That seemed to work. But I dont know if its what you want. rbd_cluster_constraint_name_fix.hip Edited May 5, 2019 by Ryan Quote Link to comment Share on other sites More sharing options...
Ryan Posted May 5, 2019 Share Posted May 5, 2019 (edited) I think this might be what you want. Try this. rbd_cluster_constraint_name_fix2.hip Edited May 5, 2019 by Ryan Quote Link to comment Share on other sites More sharing options...

isah_voodoo Posted May 5, 2019 Author Share Posted May 5, 2019 @Ryan thank you for the files. I appreciate it. The constraints are fixed but the clusters are now lost. I see what you mean about repeating clusters being far from each other. This is most definitely the issue. There has to be a solution to make it not generate two clusters with the same name that end up being split far apart. I was hoping that the connectivity would solve this issue but it looks like it is looking at each fractured piece and not the cluster. Clustering by constraints seem to be the solution but I just think it is odd that this would happen. Thanks again Quote Link to comment Share on other sites More sharing options...
Ryan Posted May 6, 2019 Share Posted May 6, 2019 You might need to reset the cluster numbers and names. rbd_cluster_constraint_name_fix4.hip Hopefully that bug will get fixed in the next release. Quote Link to comment Share on other sites More sharing options...
isah_voodoo Posted May 7, 2019 Author Share Posted May 7, 2019 @RyanThank you for the help . I am trying to do an exploded view at the end but I still can't view my clusters? It explodes each piece out. Quote Link to comment Share on other sites More sharing options...

isah_voodoo Posted May 7, 2019 Author Share Posted May 7, 2019 @Ryan This is what I get from the last scene file you sent. I am using Houdini 17.0459. Maybe thats it? Thanks rbd_cluster_constraint_name_fix4 (1).hip Quote Link to comment Share on other sites More sharing options...
Ryan Posted May 7, 2019 Share Posted May 7, 2019 Yea. That's what it is. Even voronoi fracture is different. Good to know. Quote Link to comment Share on other sites More sharing options...
