People are working on recovering PBR properties, rigging, and editing. I think those are all solveable over time. I wouldn't start a big project with it today, but maybe in a couple years.

If you want a real cursed problem for Gaussian splats though: global illumination. People have decomposed splat models into separate global and PBR colors, but I have no clue how you'd figure out where that global illumination came from, let alone recompute it for a new lighting situation.

Some intrepid souls are trying to tackle the global illumination problem! https://arxiv.org/abs/2410.02619

Wow!

Also, since it's slightly hidden in a comment underneath the abstract and easy to miss, here's the link to the paper's project page: https://stopaimme.github.io/GI-GS-site/
