Theire’s now some pre-backed Global Illumination in open word games that give an effect and “half-fake” a full dynamic GI (as enlighthen). I saw the one used in Ghost Recon Wildlands, and its impressiv (interior and exterior in the same time).
- CryEngine use now good quality dynamic GI.
- AnvilsNext 2 use a pre-backed GI technique usefull for verry large scale and small scale working in the same scene.
- Unity use Enlighten that is full dynamic RT GI, verry impressive.
And the dynamic RT GI used in the UE4 is really far to give the result of all that engine…Epic is for sure developping it to be better. I don’t think they will let the competition steal theire place (i mean, they don’t occupy the same place that much but they have to be updated with technolgy and tools), kowing that futur video games will more and more use RT dynamic GI !
