Hi, I'm quiet new in this big world of Houdini, i need help. The project consists of creating spheres on the points extracted from a pop simulation and then destroying them. The problem I encounter is that when I put the glue on different spheres it seems that it creates the glue on all the broken pieces. It could be the fact that in the assemble node, it considers those points as a single geometry, but I don't know how to divide those points as unique entities and then apply the glue only on the individual spheres and not on all of them as a single object. Thank you in advance for your attention and any help. I attach the file below. Thanks a lot! Fra_pop_copysphere_and_rbd_.hipnc -
I'm not sure if my workflow is incorrect but I have found something a little odd with transferring groups with the Assemble SOP. I was doing a sim and needed to use the rbdconfigure to set the active area. After that node however, some of my primitive groups I use to texture were either empty or had the wrong amount of primitives in them. I googled around and found that most solutions were to make sure the Assemble SOP was transferring the groups. However the only thing that got it to work was to make sure the Transfer Groups field was completely empty... I had to unlock the rbdconfigure HDA and clear the fields. Now I have all my groups and everything is working fine... As I said, not sure if I did something wrong further up the chain but maybe this is a bit of a PSA for anyone finding a similar issue.

Hello I'm doing a RBD (bullet) sim with custom concave geo (proxies) that I pack my self using assemble. I use a scatter and copy to points to set up my inital state, run the sim. I use a dopimport, and I would like to fetch the hi rez geo. Tutorials show that if I had the high rez geo scattered the same way I could plug it and it would work straight away. However I would like, with only my points, to retrieve the high rez geo. I thought I would use a foreach and apply primintrinsics or transformpieces or even a copytopoints as seen in some tutorials like here but nothign works, my scales and pivots don't seem to work. To give you an idea of what my network looks like before the dopnet: I cross posted on Sidefx forums but it wasn't published sorry for the crosspost. If you have any info on this I'm very interested.

Friends, I cry for help. For some completely incomprehensible reason, the RBD Packed Object node in the Dop Network cannot receive data from geometry packed with Assemble. The SOP Path is spelled correctly, but no matter what I do, the objects do not appear, and an error in RigidBodySolver writes: “bulletrbdsolver: Warning: rbdpackedobject1 - / obj / particles / debris_physix / rigidbodysolver1 / bulletrbdsolver: Geometry solver ". If in Assemble to disable the Create Name Attribute, the error changes to: "Warning: rbdpackedobject1 - / obj / particles / debris_physix / rigidbodysolver1 / bulletrbdsolver: Convex hunt does not have any points." Obviously some kind of packaging problem, but how to solve it - I can’t put my mind to it. I checked the official Houdini help, but did not find any special RBD Packed Object requirements for the objects. Someone wrote that he had the same problem solved by turning on the Assemble node, but in this case this node is already working ... idol1.hip axe.obj cross.obj

Hey Everyone! So the issue is... I am using Voronoi to fracture an object. The inside and outside faces are in two groups named 'inside' and 'outside'. I'm using the 'assemble' node to pack the primitives however, doing this, it looses the 'inside' and 'outside' groups which I need to use later on. Is there a way to use the assemble node and keep the groups? Any advice is massively appreciated! Thanks All!

What is the difference between creating the name attribute in the voronoi fracture, or later in the assemble?

hi everyone. i make the angluar velocity in SOP. and inheritied Point velocity in DOP. (i was modify RBD Packed Ojbect DOP like H14. this allow Overwirte attribute.) but, doesn't rotate in simulation. what made the wrong w attribute or i missed something??? i shared my hip. thanks for your read. have good day! w_attribute.hipnc
