+## Naming Conventions
+Naming conventions are important for project organization and tooling.
+
+### Material Maps
+[IronPress](https://github.com/arocull/IronPress) requires naming conventions for texture maps to be properly used. IronPress is important as it enforces proper bit-depth, performs channel-packing, and for allows bulk texture resizing.
+
+All materials and material maps should start with the prefix `mat_` and followed by the material name, such as `mat_stone`. Lowercase is required.
+
+Texture maps should be followed with specific names. Examples are provided
+- `mat_example_basecolor` - Basecolor/diffuse/albedo of material. If the material is transparent, alpha is stored on this as well
+- `mat_example_arm` - ARM is Ambient Occlusion, Roughness, Metallic all packed into one material. If the maps are separate, name them like this:
+    - `mat_example_ao` - Ambient Occlusion map
+    - `mat_example_roughness` - Roughness map
+    - `mat_example_metallic` - Metallic map, optional
+- `mat_example_normal` - Normal Map, export as 16-bit if possible
+- `mat_example_opacity` - Opacity map, only use if necessary
+- `mat_example_mask` - Mask, only use if necessary
