  1. What happens if you render the agent in Mantra?
  2. VDB Visualize Tree SOP or perhaps Volume Slice SOP depending on what you need.
  3. Just the heads or the entire agent? For the entire agent, probably a POP Look At. For just the heads, see http://www.sidefx.com/docs/houdini/crowds/states#lookat
  4. When it better to uses Volumes over VDBs? - When you don't have as mentioned above - When you have a data on nearly every voxel, making it not sparse anymore.
  5. PolyFill is one of the new options in H16 to cap holes. It's worth a try.
  6. Is your .hip file logged with steps to reproduce? We have lots of code to deal with these situations. Furthermore, I've created set ups where I've had networks loop back on itself as part of its normal operation.
  7. I spoke with one of the paper's author and he mentioned that, "The implementation of the underlying MPM solver was done in OpenVDB and all the meshing and renderings where done with Houdini (using the native VDB nodes)."
  8. If you mirror all the IK bones using the object viewport's Mirror tool, it should copy all the IK solver and goals for you.
  9. Hand-keyed is probably still "audio driven animation" albeit with a lot of manual work. The other aspect is that there's nothing wrong with manual tweaking on top of a procedural solution as well.
  10. How would $FD / $FFD behave differently to solve the issues?
  11. The traditional resource for this is the e-book "Simultaneous Music, Animation, and Sound with Houdini" by Andrew Lowell. However, his site is now down so I don't know if it's still available for purchase. However, I think Peter Quint's tutorials are still available: https://www.sidefx.com/tutorials/chops-and-music-driven-animation-i/ https://www.sidefx.com/tutorials/chops-and-music-driven-animation-ii/ https://www.sidefx.com/tutorials/chops-and-music-driven-animation-iii/
  12. What I was trying to say is that if it did get interpreted as $FF, then cases like the example I gave would get the $SHOT into the frame, thus breaking the workflow for the people using that convention.
  13. I'm pretty sure that this link error: undefined symbol: _ZN7openvdb11v3_3_0_sesi4math9TransformC1ERKSt10shared_ptrINS1_7MapBaseEE is caused by not compiling everything with -DOPENVDB_3_ABI_COMPATIBLE. One of the differences when this is defined is whether OpenVDB uses std::shared_ptr or boost::shared_ptr.
  14. I think the modern workflow is to use TopoBuild with something like the same geometry fed into both inputs.
  15. I pretty sure I've seen sequences from customers where they used conventions like: file.$SEQ.$SHOT.$F.bgeo ...
