In The Future: Nanite Foliage

I know many of us are stoked about the way Nanite deals with massive amounts of detail. What I’m most excited for is when Nanite/Lumen will support WPO so we can have proper foliage blowing in the wind, and moving when objects or characters interact with it. I think one of the most jarring things in any game is pop-in for foliage. This has been mitigated over the years by using dithering to fade in different LODs. With the advent of Nanite, the “pop-in” effect is gone!

I ran some tests for kicks, and was able to spawn in around 4 billion grass instances on screen and still maintain well over 60fps, and even over 100fps with TAA’s Super Resolution.

I can’t wait for WPO to work with Nanite/Lumen!


Foliage support for Lumen is the first thing I’m waiting for. Actualy subsurface doesn’t work under shadows so all foliage is dark.

The question is when will this be possible.

I’m also interested in this. The lack of deformation support (like WPO) for Nanite is the main limiting factor here.
In your test, are these all individually modeled grass blades with opaque material…?
