Hello everyone... I have a problem with an RBD packed object inheriting velocity. In the file, I have the attribute active being set by another object, but the velocity doesn't kick in at all. The velocity works if I remove the point wrangle setting active to 0 and remove the sop solver. If I try a pop vop or a geo vop, there's some weird velocity behavior that happens. If I tick on override attribute, the velocity takes off big time and doesn't appear that gravity takes hold. All I'm looking for is initial velocity once the pieces become active. I saw a few threads on the side fx forums and this forum, but nothing I saw seems to be working. Any thoughts? test_active_velocity.hipnc

I'm currently doing a flip tank sim with a boat as an RBD object and getting it to float. I have the floating part working, however the boat fills up with water through its hull. The odd thing is that inside mesh there are no particles. Particles collide with the outside of the boat mesh and the inside, but its as if the flip fluid particles go through the mesh. I have tried alternate collision methods under the rbd object collisions tab, but still cant work out how to stop the particles going through the mesh! Does anyone have any ideas of how to stop this?

Hi guys im pretty new here and in houdini, im currently making some experiment with houdini, but i got stuck in the dop simulation, currently i have a bunch of cubes i want to wrap each by a single cloth the problem is in fact that the cubes are merged aswell the clothes so i used the assemble node to "split" the polygons with the name attibute but i dont know how to use it in the dop network to make the cloth be affected by only one cube each ive attached my current progress, I hope i was clear (english is not my main language) cheers luca.

Hello guys ! I am trying to apply two materials with different displacements on the same RBD pieces. I use a material on the outside group and another one on the inside group. It works but it create a gap between my two materials (the black holes on the picture). I used a restposition before assigning the material with a materialSOP but it doesn't resolve my problem. Do you have any ideas of how I can fix it ? Thank you a lot !

In many threads I've read here as well as in recent webinars it is recommended to use the Deforming Object shelf tool when setting up your DOP network in a FLIP sim. And then always turn off 'Use Deforming Geometry' However in a simple FLIP sim I have with falling objects into a FLIP tank RBD Object is the only option that seems to work. If I use Deforming Object I can't get the gravity force to take effect. Can anyone tell me in a nutshell what the advantage of Deforming over RBD Object shelf tool is, and how I might enable the gravity force when applying Deforming Object to any geometry?

Hi everyone, I’m pretty new to Houdini, so please bear with me. I want to try making a little boat passing through a body of water. Now I know how to use the boat to affect the water and create the wake, but I also want the boat to be affected by the water: I’d like for the boat to rock with the water’s waves. Is it even possible for an RBD object to be affected by a flip simulation and if so how does it work? Or would I have to animate it myself? I’d be grateful for any help you can give me Thanks in advance! Cheers
