This was an odd video to do since it seems to be a simple topic but when talking about it out loud it starts sounding complicated. I’m basically covering several sub-topics which support the overall topic. Despite the confusing ramblings in the video, what you should take away from it is that in VOP COPs,

Sprites are pretty cool, but in a clean install of Houdini you can only use them on particles using the Sprite POP. It turns out, you can add some attribute trickery to make sprites work on plain ol’ points. The cooler thing is that this Sprite SOP concept works in Houdini Escape (which doesn’t have

Nothing ground breaking here, but for someone who is into neat little tricks to control shaders, I thought this was worth showing. What the video covers is a way to vary the materials on a single object using a single shader (differing from the usual method of using multiple shaders for different pieces of an

After getting something working, and continuing off and on with trying to get it to work, I have come to develop some concepts about using a Python COM method to poll 3DConnexion data. The operators at the geometry level (the Python operator and Script SOP) are unable to poll the data. This seems to be

Yes – I have something working! Read on for the story and where I’m at: I’ve noticed a problem with a lot of animated shorts and student work: The camera work is atrocious. It seems like all the time is spent on perfecting the modeling, animation, and shading, then in the last 10 minutes of

I’ve received a few requests for an asset of the occlusion inline VOP I used for the occlusion video so I thought I would put one together. I call it “Occlusion 2″ mainly because it’s the second occlusion VEX function. The occlusion VOP that comes with Houdini is actually the first function which gives you

I’m not sure why illuminance loops fascinate me so. It could be because I never had access to such a cool feature or maybe it leads me to re-visit classic bi-directional reflectance functions (I like the math). Whatever the reason, I decided to create a brdf VOP digital asset so you don’t need to type

Didn’t think the image plane series was complete enough so I tacked on this little diddy. I covers how to get object (or primitive) ids using image planes in Houdini and what you can do with them in the compositor using the lumakey COP. The compositor part I learned from SYmek, who I feel is

I’m fairly pleased with this video only because I learned a lot on my way to get this worked out. Well, I learned a lot of mistakes one could make with Houdini’s VEX like what you shouldn’t put in illuminance loops. I felt obliged to do this video since in the very first video I
