MartinB Posted March 13, 2019 Share Posted March 13, 2019 I'm having a problem with a RBD simulation. I followed Applied Houdini Rigids 3 for the setup and everything finally worked. Now I would like to work on an actual scene, using an animated alembic instead of animating in houdini with a null. But I can't see what to change or to adapt in the setup to get Houdini to read this animation and make the switch to physics work like in the original setup. Importing my abc and switching every cache to store a frame range instead of a single one might mess with the constraint system, any ideas?

tamagochy Posted March 14, 2019 Share Posted March 14, 2019 You can calculate matrix from moving object, invert it to get rest pos, make all needed preparations and multiply result by this matrix to get animated object again. Quote Link to comment Share on other sites More sharing options...
