Highly realistic model of an oak tree.
Complete with shaders and textures for both Vray and Maxwell.
OBJ and MXS version included as well.

The leaves are opactiy/clipmapped, leaves and trunk are in addition normal mapped.
The Vray version uses the 2sided material for the leaves the Maxwell version employs single sided scattering. The leaves in the Vray version do also carry different textures for the leaves top and bottom side.

Textures:
Custom bark and leaf textures derived from photographs, no random or generic textures.

3 different types of leaves with each top, bottom, alpha and normalmap in 1024*1024px.

2 different types of bark with corresponding normalmap in 2600*4096px.

Notes:
All preview images rendered with Vray unless otherwise stated on the image. Surrounding scene is not included.
No postwork was done on the renderings, all settings at default. 3dsmax was set to a linear workflow with a Gamma of 2.0 set in the preferences (important for Vray).
