Requires Unity 3.5.7 or higher.
A collection of various plants, mostly tropical, though bamboo, flowers, grass and a pine tree have been included too.
The plants use a custom shader, a variant of the cutout transparent shader, but set to 2-sided. This solves the issue of bad alpha-sorting that plagues so many games. Only diffuse textures are being used. The plants are generally between 200 triangles (smallest flowers) to around 1500 triangles (large plants).
The demo above uses lightmaps to achieve nice shadows. Check this if you want to see them without lightmaps.
