How does Robo Recall achieve the score overlay in the mirrored display?

Robo Recall somehow has a logo and high score display in the mirrored VR window. I can’t figure out how to do this in my own project. Is this functionality something related to Stereo Layers?

Epic have modified the engine source slightly to do this. If you have the RoboRecall mod kit installed, look at:
\RoboRecallModKit\Engine\Plugins\Runtime\OculusRift\Source\OculusRift\Private\OcculusRiftRender.cpp
If you search for SpectatorTexture you’ll see where they have added the support.

Right now, there isn’t a way to do custom mirror window work without such a modification. If you want it, I’d suggest requesting it as a feature on the forums.

Awesome, thanks!
