Using dophassubdata To Change Colors Dynamically
Jun 24th
It’s a fairly straight forward but I thought it needed to be put in video form. Dynamics and expressions in Houdini go hand in hand and this is an example of that. You can find the video tutorial on how to do this here and the result below:

Emitting Particles Using A Bounding Object And Its Normals
Jun 8th
There was a discussion on the Houdini forums that I took part in that I thought was worth not just one video tutorial but a three part series. I think it’s a really simple task but shows oh so much and is easily applicable to more complex work. What it covers is taking an object that will emit particles and dictating what points on the emitter send out particles and in what direction using a bounding object and one of the bounding object’s normals. You can find the videos and completed .hipnc file here.
Here is what the final result looks like (note that I changed the resulting file a bit to get a good flipbook result):
