This system looks awesome. And I think this would give really nice posebilities to mappers. All missing (or is it in and it wasn't shown) is some kind of random differences. Small color or high differences or not spawning object X just spawning obejct Y instead. For gras using 2 models is not so important but because you can use this system also for other stuff like bones or 3D floor (don't know how it is called, I mean when stones were layed side by side by humans to make a way you can use. But I do not mean the todays quality, I mean the old one with bigger highdifferences and so on) this would be very important I think. Also, would this system be able to improve the performence of whole levels by reducing the polycount of the map and "spawning" the details when you are near them? (I especially think about the sometimes much detailed stonetextures.)
All in all like always great work and I am looking forward to the next update already :)

Incredible! That makes so much of a visual difference, with so little actual difference!

You never disappoint.

Where in the video was that, though?

That looks really nice. Taking the grass colour from the texture works really well from this game, because you're just as often viewing from above as well as glancing or parallel to the terrain; makes for really nice distance transition as well.

The whole grass system also sadly reminds me to download the Black Rock - Pure foliage rendering paper and other papers before the site disappears with the studio :(

Awesome. :) Do you think you could make the grass flatten as objects hit it? Or would it take too many resources to run the collision checks?

If you can use this to create something as complex as desert chapparrel, I'd be in heaven.

If not, well the tall weeds are cool too.

This is a fantastic update! It's amazing how such a seemingly small detail can make the game look so much better!

Will you be including a way to set the view distence? One thing that annoies me on this kind of thing is where you seem to be in a giant bubble where the grass grows around you.
