I am looking forward to implement an outline PostProcessMaterial similarly to the Editor selection highlight. There are a number of resources documenting how this can be achieved using the “Custom Depth” feature.
I have been dropped off with a 4.8.3 project which I am extending. To start things off, I have enabled “Render Custom Depth” on some StaticMeshActors and then switched the “View Mode” to “Buffer Visualization” > “Custom Depth”. To my surprise, none of my nodes were visible (see image below).
However, when I setup a blank 4.8.3 project and try the same, it works as expected. Is there something like a global setting, that would disable the “Custom Depth” pass? Is there anything else, I might be missing?
EDIT:
I have just migrated all Asset files in the Content directory into a new project. In this one everything works fine. I guess my problem is kind of solved now. I would still really like to know, what exactly caused the issue. It must have to do with the project settings.
