Default values for AOV outputs

Hi all, first time posting here.

My request would be to include a simple field for the default value of a shader AOV. currently, the default (aka the value when a material doesnt define the AOV output itself) is always pure black, or 0. It would be useful to be able to change this default in the AOV section in the view layer tab Untitled.png

Good idea! Either this, or a "Exists" option for each shader AOV. For example here, you have your "Roughness" shader AOV, and some objects in your scene contain the materials that outputs this specific AOV. In the compositor, you would both have "Roughness" and "Exists" inputs, and "Exists" would be a black and white selection of the objects / surfaces that has this AOV. This way you can easily set any value for everything that's not included in the shader AOV.

You can actually set it yourself with current possibilities, but I agree just being able to set a default value could be great too
