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 PS: I also added a fun-toggle, where you can tweak your retime with spinning test-geo in case you have heavy input geo! (... which we always do, right?)

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

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.

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

Hi, the mentioned masterclass is probably this: https://vimeo.com/42988999 I also like this tutorial: https://vimeo.com/119694897 Matt Estela has great tutorials: http://www.tokeru.com/cgwiki/index.php?title=HoudiniDops# http://www.tokeru.com/cgwiki/index.php?title=Smoke_and_Pyro I don't know if there is any new video tutorial, which describes the low-level principles. I learn by digging into the "shelf" solutions https://forums.odforce.net/topic/41800-gas-analysis/?do=findComment&comment=199863 https://forums.odforce.net/topic/42101-how-do-pyro-collisions-work/?do=findComment&comment=201007 Btw, when I am digging, I use this script "Find all parms referencing this parm". http://lex.ikoon.cz/find-all-parms-referencing-this-parm/ Here is an attachment, microsolvers_dev.rar with lots of experiments, just for an inspiration. Unfortunately lots of it is outdated (it is from the year 2011) https://forums.odforce.net/topic/13748-learning-microsolvers/?do=findComment&comment=101666

YAY! I stopped being scared and dived inside the RBD Angular Spring Constraint node and worked out how to alter it so that rotations can be keyed. This means animated servo's seem possible with this setup(Though I'm not sure if this is the best method still) When I dove inside, I noticed that there was an extra parameter not exposed. Rotation. I set that to evaluate always, and created a new parameter on the top level node. Worked a treat. Now you can key rotation and it should work as expected. Now, how to get it with procedural constraints and packed geo....... rl_servo_04.hip

Higher speed will only give new mikrosolvers(HDK) with more optimized algorithms. But you can get a lot of different custom effects, or a small acceleration of the standard model, by removing some of the additions. I couple of years ago studied the effects of these guys, the projects were made for h10. http://dl.dropbox.com/u/4265149/microsolvers%20dev.rar
