Ultraman Posted April 29 Share Posted April 29 Hey everyone, I'm trying to make particles fall straight down in world space while the emitter is moving. I remember Unity has a similar concept with world/local simulation space — is there an equivalent in Houdini? My input animation is quite fast, and the ground is moving too . Is there an alternative approach to decouple the emitter's motion from the particles ? Thanks in advance! Local space Move.hip Quote Link to comment Share on other sites More sharing options...
