As you can follow up from here scene capture cube actor’s rendering properties are avaliable if you create one in the level via Modes panel, but they are not if you create one as a component in a blueprint. Is this intentional or is this something we are going to have in a future release?
I just heard back from our Engineers on this issue. Blueprint components are considered dynamic components. As such, just with any other type of component, the properties only appear in the BP Components view. You can’t modify them on the instance.
