Any improvements to lightmass is still not going to make it usable for open world environments. I wonder what kind of project file size we’d be looking at if we use lightmass on an 8x8 kilometers game world (if we don’t die of old age before lighting is built).

It’s better to ask that super caliber team to do IBL first so people can actually use it for large outdoors, then work on new hypemass features that’d be used for next gdc floor.

I agree. not sure why people get excited with new potential Lightmass improvements when it’s mentioned in these threads about dynamic GI

btw I had a shot at the IBL thing I mentioned with reflection captures.
I was able to make reflection captures show up as lighting but the results are worse than I expected. captures can “see” to infinity which means any bright spots will leak inside windows/doors/etc indefinitely, no matter how far they are (I’d probably need a ‘maximum render view distance’ for captures, but then it wouldn’t work for reflections anymore. alternatively if captures had depth I’d be able to filter out far objects by distance, but I doubt probes have depth information).
aside from that there’s a big issue that capturing probes will accumulate over themselves each time you capture them, since they are already affecting the scene as lighting. as such, I have to turn them off every time I want to recapture and then turn them on again.

these issues severely affect its feasability, and the more engine changes I have to make, the less chance that it would ever get accepted as a pull request (chances are already slim, since they removed the DiffuseFromCaptures feature in the first place)
in any case I’m focused on other things at the moment so I can’t work on this currently. but if there’s interest I can at least post some screenshots of my progress
