Houdini 21 | Karma retime instance | RBD Solver | 4K
This is an R&D test exploring Karma retime instancing and its impact on render efficiency. All the shots shown here are generated from a single explosion, with variation created through different scales and rotations.
Using the exact same scene setup, the difference between rendering with instancing versus without it can be over six hours as you can see in the video, or in some cases make the scene unrenderable.
I also discovered an excellent Hex-Tiled Texture node that fixes tiling issues very effectively. Big thanks to @DoubleJumpAcademy for sharing this.

I also used this opportunity to experiment with wedges by building an automated test setup, also learning to procedurally control explosion timing and crowd layout.
The scene was rendered in Karma XPU and composite in Davinci Resolve.
