@seetherlee Thanks! Opacity maps were used to keep polygon count low, but geometry was built to follow the leaf shape as much as possible to cut down overdraw and improve performances.
@minifloppyit I have a tree that uses opacity maps. In 3ds max I can see it and it looks great but when I import the model into udk the opacity map is not there and you can see the parts of the model where the opacity map is suppose to be. So how would I get an opacity texture to appear on my model?
@BritishAirwaycaptain You need to use a masked material inside UDK. You can find more info on how to do this in the official documentation on the Unreal Development Network (UDN), just Google for it. Hope this helps.
@BritishAirwaycaptain Before importing the model in UDK, you will need some vertex color setup on your model as specified in the "Modeling Tips" section of the tutorial. Once you have your mesh inside UDK you can just plug your textures inside the provided example materials and you should be ready to go. :)
wow. many many thanks!

Wow looking good. Alpha textures on the geometry or is it all mesh?
