3D Dynamic Volumetric lights for Godot 3 [GLES2]
That's really cool

YYYYYEEEEEEESSSSSSS!!!!!

Oh. It's just a fancier godrays effect. Clever use of viewports though. :)

Infact, you've inspired me to redo my volume renderer add-on. It'll be based on frostbite's approach this time, so it'll have downsampling, temporal reprojection and (probably) work with transparent objects.
Oh. It's just a fancier godrays effect. Clever use of viewports though. this is not godray effect
this is cubemap depth sampling, with only 16 or 32 steeps that very cheap and can work on 60 FPS even on low-tier video cards
Yes I know you are sampling from a pseudo cubemap. That's why I said it's a fancier God rays. Because you are sampling from a cubemap as well, for a more accurate God rays effect. But in retrospect, the term might not have been the best one to use. Great job either way. :)

Not so true for integrated GPUs though (obviously). I think I got like 20 fps in the demo. But that's expected.

I test myself on Vega8(Ryzen3) 60FPS on 1080p with 32 steps, ofc 90% GU usage, with 16 steps only 50% GPU usage
