Rendering Instanced Geometry ¶
When you create a particle system, Houdini also creates a renderable object at obj level. For example, if you create a particle system with the Location Particle Emitter shelf tool, your renderable object will be called location_particles
.
-
In order to render instanced geometry, append an Instance SOP after the DOP Import Fields SOP node inside the renderable object.
-
On obj level, turn on the
location_particles
node’s blue Display/Render flag. If necessary, turn off other Display/Render flags to render only the instances.
Motion blur ¶
When calculating motion blur, Mantra by default assumes the geometry of an object is unchanging, and blurs it as a whole. For a particle system obviously the points are moving, so you need to turn on velocity blur to use the velocity (v
) attribute of the points to blur them individually.
To enable motion blur on particles you must enable it on the object as well the render node.
