Creating foliage grass

For grass I'm going to use some reference that was available in udk package

Grass texture on the ground mesh is to flat using planes gives the better impression of grass in a 3d space, by duplixatng and roaring planes with a two sided texture its easy to create a clump of grass strands.

Creating the alpha was rather simple I created my own way in Photoshop by using the lasso tool drawing a shape of a leaf and then filling it in, for the stem I painted it in and using burn to create shadows.

From here you can export the planes as a clump as a single object and then place duplicate and rotate across the landscape surface.
