We are a couple of people doing a hobby project for UE4 and had some vegetation left that we did not use eventually.
So we decided to give it a go and to submit it the marketplace.
the specular effect is only in this particular scene. Parameter for specularity etc. are hooked up.
poly count is left rather high (>10000 triangles) because it was the strategy in our development to have high quality and only decrease poly count on demand.
OBJ and FBX are all included so that everybody can strip polygons on demand.
