Houdini - Import / Export alembic animation with chopnet and use it in a simulation pretty handy when deal with fast moving object easy to sim (再次感謝 John Kent :) ex. Fast moving object on fire or fast moving container with liquid In Sop Chopnet > object / target object "geo node under alembic">export / channels : t[xyz] , Node "target transform node", path : t[xyz] also another one for rotation (r[xyz]) ps: In houdini16 they change the "export tag" and "lock tag" position in network viewer. option > Set Normal to 0,1,0 define a up vector (can be set as gravity in liquid sim) Right click transform node / action / create reference node and select the invert transformation. so move it back to the origin position for sim In Dop Pyro - bring in V to buoyancy: buoyancy lift should be length from v dir should be v itself Liquid sim - bring in N ...
