aiLayer shader order?

[aaronfross]

Hello,

In the MtoA documentation for aiLayerShader, I see the line "Layers are applied in order." I assume that other plugin documentation shares this issue. The statement is ambiguous. In what order are the layers applied? Top to bottom? Bottom to top? It could be either way, and the documentation is not helpful. Different applications use different conventions. E.G. Photoshop and After Effects layers are composited similarly to the UI layout... layers higher in the UI are superimposed over layers lower in the UI. The Maya Layered Shader is horizontal, with left-hand layers superimposed over right-hand layers. So how are users to know that is meant by "Layers are applied in order"?

I experimented with aiLayerShader and determined that higher-numbered layers are superimposed over lower-numbered layers. I.E., layers lower in the UI are superimposed over layers higher in the UI. Please update the documentation to clarify this issue.

Thank you,

Aaron
