Made 4 fern plants to vegetate the area. The small ones are 320-360 Tris and the big one is 730 Tris. I have also made an animation shader inside UDK so that the plants move on the wind. This involved changing the vertex colors of different part plants so that they move independently. The shader was based on offseting the vertex positions by the vertex color. Will post a screenshot of the shader setup later on.
Here are the plants :)
Just need to adjust some color values to the texture.
This is a really late post. Got more updates and will post them soon.
