Last weekend I took some time to add a new feature to the engine. It is some sort of mesh instancing system that brings additional detail on top of the geometry output. It can be used to add a new vegetation layer under trees, like the following images show:
I will be using it for rocks, pebbles, even man-made elements sticking out of the blocks you place.
Polygon counts are now escalating quickly because of this. My old 4770 still averages 40 FPS at 1080p but begins to struggle. It is still manageable, there are some polygons right now I can cut.
This one was long needed. I will be posting a video later so you guys can see how the LOD transitions are managed. I think this has improved a lot.
