Video where I try to explain the basic techique of accessing 3d geometry attributes from compositing networks (COPs) in Houdini. This is essential for doing advanced procedural texturing right inside Houdini.

This video is part of my article series about procedural game asset pipeline in Houdini. You can find it here: http://www.rendereverything.com/game_assets_with_houdini_1/

So glad to see my little Youtube Channel reaching 3000 subscribers. To celebrate the moment I put together this scene in Unreal Engine 5 over the weekend using its Nanite and Lumen features. Also, wanted to explore the workflow between Unreal and Houdini. Thanks to Engtama for awesome tutorials.
Couldn't get a smooth export and import from Houdini to Unreal so I had to bring the geo to Blender first. Geometry caching in Unreal is still in the experimental phase so I anticipated that, maybe the Houdini engine would have been a better option.
Things were pretty easy on the Unreal side. It's quite incredible how much geo you can load with Nanite. Lumen was fun to experiment with. There is some flickering happening in shadows but I am not sure how to solve it may be fiddling with the raytracing and post-processing setting could solve it. Learned so much though.
The scene was captured at 64 samples with raytracing on using an RTX 3090. Thanks to the movie render queue which helps to output passes and get a much more…
