Betula pendula, commonly known as silver birch, warty birch or European white birch.
The silver birch is a fast growing, up to 16 m tall tree. Its stem is reaching far into its crown or multiple stems growing from the ground. A optimal place for a birch tree is sunny and coolish to modest warm.

Textures created with a self-build rig of eight light sources with a polarisation filter in front of each. The camera got a liquid crystal polarisation filter to capture the subject with and without reflections.

The photos were colour graded (colour checker) in lightroom, the front and back side matched in photoshop. After that, they were imported into Houdini to create the various maps. Height and AO were created with Knald from the normal map.

Following maps are included for both front/back in 1k/2k/4k/8k:
albedo
ambient occlusion
transmissive
glossiness/roughness
specular
normal
height
opacity
16/32 bit maps are saved as .exr
8 bit maps are saved as .jpg
lowpoly geometry is saved as .fbx

Renderings done in Houdini with Mantra.
