  1. RBD WORKFLOW H18

    Hi! I've been working lots of rigidbody simulation lately. I am happy with what Sidefx has done for RBD Workflow specially when they release houdini 18. Sample workflow: -Prep objects. Categories/separate like (GLASS,METAL,CONCRETE,WOOD) to Groups. You will use this for RBD configure. -Clean objects. Check for holes, wrong normals, unused points,etc.(Clean Sop/Facet Sop) -Check the UV.(This is super important after the simulation so that you will not have a hard time doing the Materials) -Prefragment objects.(RBD Fracture Material). For the constraint i prefer doing it after the fracturing. -Make inside UV for inside faces(UVunwrap selecting inside group). -Cache Prefragments Per Object.(RBD I/O) 1 frame only. -Make Constraint. -RBD configure(this will help the solver a lot because you can set the density/type of material like GLASS,METAL,CONCRETE,WOOD) -RBD solver. Configure the Constraint for breaking, Forces and Collisions. -RBD I/O to cache the simulation. It is good for simple shots or scenes but when it comes to heavy scenes i notice that it is to heavy to load when opening the scene especially when you have lots of object to prefragment(RBD Fracture Material). Anyone having the same problem? even if you cache your objects the scene is still heavy/too slow?
  2. You have a point there and agree with that its just im kinda used to thingking particles where everything is rigidbody collision. Anyways Awesome awesome awesome tips again! Thanks for your help guys!cant wait to try this on my effects shoots!
  3. Hi guys thanks for your help i try using the Glue for RBD sim and emit some debris. Any suggestion on how to improve this? -collisions of debris as rbd not particle or point collision -randomization of instance/copy Thanks! RBD Glue Study_v2.hipnc
  4. Hi guys! Im a 3ds max(Thinking particles) user and my company require me to shift to Houdin. Is there a way to do this in houdini? I tried using rbd and bullet but it show weird result like in first frame it explode or all of the pre fractude object starting to move. Can anyone share a similar hip file similar to my test in thinking particles? Thanks!
