Image Planes Part 4 (Object IDs)
Nov 19th
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 Houdini community (and who I had an argument with about points on the Sunflow forum a while back 
).
Image Planes Part 3 (Light Export)
Nov 18th
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 about light export in the image planes. What this covers is how to get planes/passes for each light in the scene. You can find the video as well as the final hipnc file here. The final hipnc file has specular components added which I didn’t cover in the video since the technique to get the diffuse planes is so similar.
