SceneCaptureComponent clear to colour rather than skybox

I am using a SceneCaptureComponent2D but when it sees nothing, despite the MaxViewDistance being set, it appears to render the skybox. I would instead like to specify a colour that it would clear the render target to if it doesn’t see anything.

I’ve had a dig through the rendering code but it looks to clear to black before rendering (Not the colour I want sadly) but it is still rendering the sky sphere. How can I configure it not to do this?

As a work around I can put something in the way but this is less than ideal.

I’d be interested in this too. Adding the actor of the skybox to the “Hidden Actors” array doesn’t make a difference as far as I can tell.

Another approach may be to use the depth buffer to detect “far away” (= skybox) areas inside the material, but that wouldn’t be as reliable and clean.
