I have extensive teaching experience as both Lead FX Instructor at Lostboys School of VFX in Montreal, and I am currently Head of CG for Onboarding (new hire training) at Cinesite. I focus on the fundamentals, so that you understand what you are doing and why you are doing it -- that you can take what you learned and actually use it to create new content.
I have also been using Houdini since its inception, way way back in the before days. I still love what I do and hope to keep on doing it for many years to come! less

Just in case anyone is looking at this in the future, it should be noted that you will not be able to see your brush while viewing the monotorgb output as in tampte's second GIF if Edit -> Preferences -> Objects and Geometry is set to "Geometry View Shows: Node with Display Flag".
Viewing through /stage camera with BG in SOP Create LOP Oct. 29, 2026, 4:53 p.m.
I have created an arbitrary camera in /stage with a BG image. I append a sop create, so the camera is piped into the sop create. I want to look through that camera in the SOP context, with the supplied BG image. This works fine in H21, does not in H22.
I also tried this:
Is this just broken? H22.0.368
I also tried this:
- Camera Import SOP - still can't see the BG image
- LOP Import -> Unpack USD SOP - this does not even need to be wired into anything and you can see the camera in the menu. (I can't believe this works, Gemini suggested it and I thought it must be hallucinating.) However, no BG image.
