What is the best way to render a texture across the screen in VR?

I’ve been struggling with the simple task of rendering a texture, from end to end across the screen, and for VR, across the screen for each eye. It’s a simple vignette. I’ve been doing it through the HUD, but when using an Oculus, I get funny numbers in SizeX and SizeY and struggle to find the right numbers when using DrawTexture in there.

What would you do to draw a single texture across the screen?


Are you talking about like a widget? What do you mean a texture across the HUD?
