Here are the changes:
- From 10 layers to 16
- Reduced the interval between top layers compared to bottom layers, as I need more details at the top of grass blades. This make the 16 layers look about the same as 20 layers.
- Made the grass blades bend more along a curve when pushed by the wind. Also reduced their height when pushed a lot, so that they look more like actually bending, rather than being translated/rotated to the side.
- Made the occlusion (darken the bottom of grass blades) to happen during light calculations, so that it uses the correct shadow color and doesn’t happen in part already in shadow. It used to simply darken the grass color no matter what.
