Geometry is imported for each particle system cache. Houdini’s sprite node that is in the POP network doesn’t really function for prman. So I had to copy little circular grids on particles with template point attributes. I had to make sure that the grids would face the camera at all times, so while...

The effect I am trying to mimic is from Fellowship of The Ring. Specifically the smoke ship Gandalf character creates while smoking a pipe.

I am using Houdini to build the geometry for the effect, which was a challenge at the beginning since although I have been using Houdini over 7 months now I...

This was just a mocap test of two actors captured at the same time. The 3D models are pretty simple and ugly, but that wasn't the point.

Two actors on the left were captured at the same time, ones on the right were the same actor captured at different...

This is a shader which fakes the sub surface scattering effect in RenderMan efficiently.

Here is the algorithm for the shader:

  1. Before anything else, backup the point and normal attributes of the surface, and set the opacity
  2. Setup the reflections t...

I haven't modeled this car, but I've set up the materials for it as well as the HDR lighting and shooting the background plate. The model was a little too heavy to a...
