I like that they distinguish between the collider mesh (lower poly) and the detailed mesh (higher poly). As a game developer I'm looking for: • Export low-poly triangle mesh (ideally OBJ or FBX format — something fairly generic, nothing too fancy) • Export texture map • Export normals • Bonus: export the scene as "de-structured" objects (e.g. instead of a giant world mesh with everything baked into it, separate exports for foreground and background objects to make it more game engine-ready. Gaussian splats are awesome, but not critical for my current renderers. Cool to have though.

Aren't the gausian splats the output here? Or are these worlds fully meshed and textured assets? From my understanding, admittedly quite a shallow look so far, the model generates gaussian splats then from that could implement the collider. I guess from the splat and the colliders you could generate actual assets that could be interactable/animated/have physics etc. Unsure, exciting space though! I just don't know how I would properly use this in a game, the examples are all quite on-rails and seem to avoid interacting too much with stuff in the environment.

  The page shows, near the bottom, how the main output is gaussian splats, but it can also generate triangular meshes (visual mesh + collider). However, to my eye, the triangular meshes shown look pretty low quality compared to the splat: compare the triangulated books on the shelves, and the wooden chair by the door, as well as weird hole-like defects in the blanket by the fireplace. It's also not clear if it's generating one mesh for the entire world, it looks like it is - that would make interactability and optimisation more difficult (no frustrum culling etc, though you could feasibly chop the mesh up into smaller pieces I suppose).
