In the break down video in the OP I go over the instance material and the parameter that is used to cap off the grass at certain heights.
I’m at workf right now but if you look into the main material there is a material function and out that comes one line to material. and 3 lines to the grass type that have the mask. if you change the output of the material from being an attribute you can then plug the grass type make into the material color section of the material output.
