Pack Info:
Trees Textures Vol 1 1 contains 22 high resolution tree textures for use in your 3D and Architectural projects. The trees in this texture pack are based upon Young Maple Acer Campestre trees commonly used by Landscape designers to provide street foliage in new build areas. All textures are derived from 3D Tree Models created by ambientLight. Each texture has an alpha map for use alongside the diffuse texture for perfect blending into your scenes either by direct compositing or billboard rendering.
