  1. Past hour
  2. Because today was another day where I went nuts trying to figure out retiming to be 'right', I now took a bit of time to build this retimer, which works a bit more intuitively. It works via a solver - so now you can animate the speed of the input, like in Premiere, and the output duration essentially gets stretched and squashed automatically. Because the solver is simply a recursive calculation, the solving is instant - when you re-animate the input time, just hit "Reset Simulation" and you're good. Maybe it's useful to somebody! Here it is for download: retime_solver.hdanc (H17.5) (While it's just a non-commercial asset, it can easily be rebuilt in a couple of minutes. The groundwork is done. All the best, Martin

  4. houdini 17 Bullet Bendable Constraints

    Hi guys, I've been trying to make the constraints bend. I've taken a lot of documentation and made a simple setup, but it's not very successful. I don't know where the problem is. Below I will upload my file, please help me to see where the problem is, how to make the right settings. Thank you all. test_bend.hip
  5. imported geometry pivot

    Try Alembic then! if you import in Houdini you will have a Alembic Xform Node that should hold all the pivot information you need.
  6. imported geometry pivot

    As I know obj don't retain original tranformation. FBX, 3ds, Alembic, collada, does, but I don't try all these in houdini, just fbx and Alembic.
  7. or Measure SOP, which was updated in 17.5 and has several useful curvature modes
  8. because you are using RBD Solver and that doesn't care about packed geometry use Bullet Solver or Rigid Body Solver with Bullet engine
  9. GameDev_measure_curvature node and maybe this helps
  10. Hi Guys; Is there any way to select and masking curvature (cavity) on a geometry, something like ambient occlusion masking (or erodes)? Thanks.
  11. Hi; In my very simple "RBD" simulation, the RBD solver simulates all of my packed geometries as a single object. How can I fix it? Thanks. RBDPacked.hip
  12. Thank you "LaidlawFX", so is there any example or tutorial about how to use it?
  13. Script to resume crashed render

    Thanks for everybodys input. Ive ended up going with the free version of Royal Render, and it has been relatively easy and effective to setup on a single machine, and I have very minimal networking skills. For whatever reason, I was finding that the rrSerivce was not resuming my renders on a system restart, so I placed the win__rrClient.bat into the Windows startup directory to force it to start.
  14. imported geometry pivot

    Thank you Fred! It helped me a lot. FBX is fine I think. on the other hand .Obj files are not. so I need to import all objects from maya via FBX format to retain its original transformations?
  15. So I cached my nparticles that were imported via houdini engine into maya. When I import them back into the scene via nCache > attach cache it makes a cacheblend input on the nparticles. Great, but when I open the scene on another computer on the network that does not have Houdini the cached particles do not load at all. I need to render this on a farm and be able to load the scene on any machine and see the particles.

  17. imported geometry pivot

    Hi I'm not sure about you problem as FBX import usually give the correct pivot. I try it (from an older version of maya), and I get the correct pivot. See the attached file. The pivot of pCube1 is on the top left corner. Normally you should see at the bottom of the geometry transform tab, the pivot offset parameters. These settings are not normally usually visible, they are added when importing FBX. But you can access it or add them from "Edit parameter interface". I also added a box, where I added the rotate offset (but in the transform tab to make it more visible), and move the pivot to the left side. If you want to use these "not centered" pivots at the sop level you have to use several transform node to recreate the transformation sequence. hope this helps Box pivot.zip
  18. keep uvs on flip anim

    You need to unpack Alembic before you begin processing. Here is a revised setup using a .abc file. There were some errors in your file. There are some UV anomalies, but if you increase the FLIP resolution (which is matched to the pointsfromvolume resolution) the anomalies become less obvious. mb_african_femal_01.abc ap_flip_UV_transfer_001.hiplc
  19. imported geometry pivot

    thank you but, It is not what I want. I don't want to move the pivot to centroids of the entire object or any primitives. I need the exact pivot position of the object shown in the picture.
  20. imported geometry pivot

    just blast the lower polygon and put transform node under it with expressions sepu mentioned. or you can blast that polygon put null at the end with name OUT_whatever(just to keep it organized) and then on transform node that is just under your geo put expression in pivot position centroid("../OUT_whatever", D_X) centroid("../OUT_whatever", D_Y) centroid("../OUT_whatever", D_Z) for XYZ accordingly All done in geo level
  21. imported geometry pivot

    well It works just fine for the pivot of the bounding box. but what about an arbitrary pivot like this: and rotation?
  22. Pop forces falloff options

    If you want something more visual you could always use the Mops Fall-offs or I believe in 17.5 H also add it a falloff node, which in my opinion isn't that great or you also have Lynx by Luca https://www.motionoperators.com/
  23. imported geometry pivot

    Should be able to open the pivot transformation tab in the transform and add $CEX and $CEZ.
  24. Logarithmic slider [-X, 0, X]

    make ramp from 0 to 1 then fit ramp from -x to x
  25. Pop forces falloff options

    Use VEX in those nodes, find distance, fit it and multiply to force.
  26. Hi, is there a way apart from rocket science to control the area affected by pop forces, for example adding a spherical soft falloff to a pop wind node or a noise-based falloff? Thanks!
  27. imported geometry pivot

    thank you Adrian! the thing is I need Its pivot exactly where It is in Maya, so I can rotate it around. the pictures shows what it looks like in Houdini. (obj and FBX in houdini)
