This pack contains 74 models (22 unique models plus additional LOD stages and 2-sided models).

Dreamland Vegetation model pack by Johan Svensson

2-sided models contain foliage material that is doubled and flipped. So you dont need a shader that renders foliage 2-sided. You can use a one-sided foliage shader instead. In both cases foliage materials need a shader that reads opacity data from the alpha-channel. Additional textures for normal, height, opacity and spec maps are included. All models SHARE same textures (only 6 textures for ALL 22 model)!
