Magnopus engineer admits his 'unlimited' Gaussian splat renderer had a hidden 16-million-splat cap
Gaussian Splats part 3: There's always a bigger scene
After claiming his Unreal renderer could handle unlimited Gaussian splats, the author discovered a hard 16-million-instance limit baked into Unreal's GPU Scene. He rebuilt the pipeline around indirect instanced draws, freeing the ceiling and enabling per-splat GPU culling. Then memory became the next wall: real photogrammetry captures exceed VRAM, forcing a switch to PlayCanvas's Streamed SOG format with screen-space-error LOD selection and asynchronous chunk streaming.
Well, as it turns out, I celebrated way too soon when I claimed a capability of rendering unlimited splats.

There's an interesting recent Siggraph paper on scaling up Gaussian splatting in a very different way, which offers some interesting benefits; Gaussian point splatting.

Gaussian Splats are great, and putting them in Unreal is even better! Do you see splats cropping up in games/sport events? Where next?
Gaussian splats are surprisingly easy to make: https://superspl.at/scene/82eb1744 (I used a thermal camera - so I could also project the IR onto it too)https://superspl.at/scene/f9672a5e

With the simple equipements, the result is spectacle.
