AOV Classifications
Output AOVs
These are effectively composites. Each separate layer in a single Output AOV is composited on top of the other, bottom to top. Each has a separate blending mode, just like a layer in Adobe Photoshop. Multiple Output AOVs can be present in a nodegraph, but they are self-contained and do not effect the others. For composites, only the layers within a singular Output AOV matter.

Render AOVs
These are passes from the render itself. To be used in a comp, a Render AOV must reference the pass from the Render AOV Parameter menu. Each Render AOV node contains Blending Settings, referenced when used as a layer in a given Output AOV.

Textures
These are all of the available Octane texture types (gradients, procedurals, etc., used as inputs to the Composite Texture node).
- Texture Layers — Effectively "Composite Texture Layers" as these items function as layers for the Composite Texture node, and are the only type of layer which can do so.
