AndrewVK Posted January 14, 2003 Share Posted January 14, 2003 Say, there is a particle system in object A. Every particle has Scale, UpVector, ID attribute. If i switch object A to Point Inctance mode and choose object B as an inctance, then during render process Houdini replaces every particle with object B and scales it according to $PSCALE attribute. BUT! It does not rotate them according UpVector, though docs say it should: "If an up vector exists for the particles, it will be used to orient the instanced geometry. You create and control up vectors for particles by using a Point SOP." So what am i doing wrong? Say, object B contains only a Bounding box, while it is switched to Bounded File(BBox from render SOP) mode, where a special application is called as a file which generate object dynamically. So is it possible to transfer particle's parameters (for which application is called) like Scale,ID,Current Time to this application as arguments ?
