PBR stinging nettle

The assepack contains a European stinging nettle plant, collected in Germany and scanned with photogrammetry.

The pack includes:
5x 4k Textures

-normal
-height
-gloss
-alpha

3x different growth stages:
- large nettle (56 tris)
- middle nettle (28 tris)
- small nettle (24 tris)

2x example unity tree-creator prefabs for Terrain

All meshes have been optimized for minimizing alpha overdraw and therefore have a slightly higher triangle count than normal billboards. PBR calibration is based on Unitys calibration scene with deferred lighting and linear color-space.
