Ok I fixed it.
In my camera actor BP the default scene root was a static mesh that was scaled to 0.2 and was hidden in game.
I got rid of the old scene capture component and changed the actual mesh and set the scaling back to 1.
Then I added a fresh capture component and connected all the scripts back again.
Now everything works…
I don’t know what the problem was, but I would guess that it was related to the scaling of the static mesh in the root.
Is there anyone from the ue staff that could explaine to me how this could happen?
Cheers
