Houdini Occlusion Asset

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 occluded irradiance which is a ... Read More...

Houdini BRDF Asset

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 a lot to get ... Read More...

Image Planes Part 4 (Object IDs)

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 an integral part of the ... Read More...

Image Planes Part 3 (Light Export)

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 mentioned that I would talk ... Read More...

Image Planes Part 2 (An Occlusion Plane)

Okay, so I went a bit off the track on this one. It's loosely an image plane video and more of a "how to do an occlusion pass inside a shader then put it in a plane" video. So I'm not sure if I should keep it under the "image plane" heading or create some new one. ... Read More...

Image Planes Part 1

I'm loving Houdini shaders and image planes are just icing on the cake. I thought I would run through the basics first then in a later video(s) get into extracting specific data into planes then cover light exports in image planes. So you can find part 1 here! Read More...
