I think it's shocking that this has no replies. I have no interest in turning my 3d scenes into 3DGS, but I have a huge interest in going out and capturing a location and turning it into a 3DGS. This is something fantastic for arch viz, which is Coronas main audience, right?
It's been oddly quiet on the autodesk, v-ray and corona front about this tech. The UE, Blender and Unity scene is all over it. Alteast from my biased internet bubble.
This is what's going to push me into doing an actual project in UE soon.
If any developer sees this, I would be really interested to hear if the ability to read and render 3DGS would be best implemented on the autodesk/Max side of things, or in the actual renderer. So I know who to nag ;)
