I am currently using the OVROverlay system when the player is loading certain data to avoid headtracking issues.
Right now, I have two overlays in the scene:
1. A cubemap with a custom texture
2. And a quad to display loading progress.
Overall, the system works, but I would like to be able to fade in the overlays rather than just turn them on and off.
After a tweak to the Texture2D Blit.shader file (just manually adjusting the alpha value of the final color), I was able to get the quad fading in and out, but making the same change to the Cubemap Blit.shader file doesn't seem to actually do anything. So, I was wondering if this functionality is actually possible?
