Here’s a new video demo of the Occlusion system for the next 1.20 update. It automatically occludes any material effects under “roofs”! Also there are all of Weather Material FX for this moment: Wetness, Puddles, Ripples and Snow.

I still need to optimize it a little bit more, but even now it’s pretty fast.
There’s also one thing to mention… Since Occlusion system captures a render target for world height, it also can be sampled by a GPU Particles, which means they now can be occluded as well! Meaning - very dense downpours and snow blizzards without severe performance hit. Though I think it has to wait until next update after release of 1.20 - there’s still a lot of work to be done.
