Tortle 2
Just some updates to the environment.
For the grass, I'm using this shader with some minor modifications:

My modification is to allow more than one object to 'trample' the grass (the grey sphere target and the tortoise). It's nothing complex, instead of using 1 float4, I have an array of them and then have that array set in a normal C# script at runtime. It's probably not the most efficient thing ever.
For the volumetric lighting, I'm using Aura 2 which I got from the Unity asset humble bundle (not sure if it's on sale anymore)
For the trees, I'm using MTree which I also got from the Unity asset humble bundle.
