Surprisingly good.
I was wondering if it would be possible to have some of the plants as a separate file that can be removed if we choose. The reason I ask is, for those of us that don't use CSP, it still looks very good but unfortunately some of the 3D grass looks like it is floating in the air without the Grass FX to hide it.
If we have the option to remove that floating grass, it would look more finished.
If you load the track with the vanilla launcher, you'll see the 3D grass in question on the left of the track.
