Between this and your multi-lightmap solution, you’ve certainly got my attention, this is pretty impressive. Two questions actually, one about each project.

For this, does this work with fully dynamic lighting by any chance, or do you need to bake it down like in your github’s readme?

Also, for your multi-lightmap project, how scalable is it exactly? If I throw the multi-lightmap build at a scene around 16km large, would it work properly or do you find that for something like that, fully dynamic is still the better option?

1. DFIS needs irradiance information from indirect lighting cache to work, but I think it may also extract irradiance from other GI solutions like LPV, PRT etc., of course you have to write it yourself…

2. Multi-Lightmap Dynamic Blending has two major problems, one is storage size, another is light building time, so in my opinion it will not work in a huge scene.

PS: Since MLDB will also blend indirect lighting cache, so MLDB+DFIS can fake some ‘real-time’ GI.
PS2: MLDB can be seen as some form of PRT, but very limited.
