catchyid Posted March 12, 2020 Share Posted March 12, 2020 Hello, I have an imported animated object (alembic + it's both transformation and deformation, e.g. IK chain that deforms a mesh). My goal is to constraint another RBD Active Packed objects to the deformed imported object. I have two questions: 1) How to do this in Houdini? I've tried different settings for the animated/deformed objects in Houdini, but in all cases, it did not work (sometimes, the deformed object moves but not the constraint, sometime the constraints jumps irrationally, etc.) 2) To have a better understanding of the shot here it's description (just in case if there is a better way to do it other than constraints): a metallic structure (attached to concrete ground) deforms and moves in an upward direction --> when it moves up, it should take with it part of the concrete ground and this concrete ground piece should break gradually. Thanks Quote Link to comment Share on other sites More sharing options...
catchyid Posted March 12, 2020 Author Share Posted March 12, 2020 just a quick update if someone is still following , Houdini 18 supports this features out of the box so problem solved... Quote Link to comment Share on other sites More sharing options...
