Be sure to study Houdini's
packed primitives - now the preferred workflow for geometry!

Lights.

- Instancing: Tons of geometry? Refer to instanceNode.hipnc. For geometry use fast
point instancing, for lights full
(As of H12 you can see the instances in the display) - Instance variation: Remember that instances can also have point attributes for variation. This makes them even more powerful. See the example file instanceAttributes.hipnc.
- Instance attribute If you want to use multiple object on a set of points, here is a sample file multiInstancesRandExample.hipnc
- Instances with the copy node, here is the sample file CopyNodeInsideInstance.hipnc
- Instances with a popnet, here are a few files that use this technique for an easy way to get "collision detection" while scattering points: particlesToScatterH13.hipnc (and a version with materials, particlesToScatterWithMaterialsH13.hipnc) as well as particlesToScatterTightlyPackedH13.hipnc. (For really avoiding collisions when doing layout, use an RBD).
