I've watched a few tutorials for making grass in UDK, they all pretty much use the same technique, Drawing mask in photoshop then using a color gradient for the diffuse. Applying this texture to a plane and adding a few splits and bending it so that it can be viewed from above as well as from the sides.
Ofcourse you need to have two sided material enabled in UDK, this is unimportant in maya/max.
This is my diffuse map
This is my alpha channel to mask the diffuse.
Test renders in maya.
A couple of screenshots of testing it in-engine.
I still need to work on getting the smoothing groups to export and I have yet to enable the object to cast shadows but it's working!
