Each material is delivered in two forms :

• A Substance .sbsar file allowing for procedural smart material generation and additional fine-tuning. Each Substance .sbsar file can generate resolutions from 256x256 to 4096x4096 pixels.

• 3 sets of texture maps : 1024x1024, 2048x2048 and 4096x4096 pixels.

Each Substance .sbsar file allows for specific procedural changes to the material : you can change or randomize the location and density of elements and shapes, change the moss or snow level, the color tint, the resolution, etc.

These procedural changes allow you to fine-tune the material to your needs or create variants of the same material to avoid repetition.

The Substance 3D for Unity free plug-in needs to be already installed for the .sbsar files to work, you must have an /Adobe folder in your /Assets project folder.

All assets are compatible and tested with the Built-in, URP and HDRP pipelines.

The 4 materials in the package are as follow :

• Pine tree bark

• Birch tree bark

• Plane tree bark with exfoliating patterns

• Old tree thick bark

All 4 materials have a moss and a snow procedural generator that come on top of the base layers.

If you use a Unity version prior to 2020.3.27, the Substance 3D to Unity plug-in and its associated .sbsar files are not expected to work. Nonetheless, you can still use the texture maps provided in the package with standard Unity Materials.
