OpenXR and Gamma Color Mode in Unity
We have a VR app we'd like to bring to Oculus platforms, and it's made in Unity using the gamma colorspace. We're finding that the OVRGradleGeneration build step reports the following: "Oculus U...
Well, we ended up putting in the work to upgrade to Unity 2021. We're using the Vulkan renderer, which works in Gamma color space. Still on Oculus XR plugin version 1.11.2, from the package manager inside Unity. So it all works, and the Unity upgrade was pretty easy for our project this time.
Interesting. So, if I use OpenGL and if I upgrade to 3.2.2 it won't let me build because of the color space issue. Are you suggesting that I can get around this by switching to Vulkan? And you've seen a little performance improvement with Vulkan, huh? About to try it!
Yes, definitely move to Vulkan if possible. We're stuck on OpenGL on Pico because the headset doesn't support it... and on older versions of Unity we ran into bugs with Vulkan. Or unsupported features. It will depend on your render pipeline choice as well, unfortunately. The landscape changes quickly since it seems like there can be separate issues in different versions of each VR platform's plugin, each unity version, each unity render pipeline version, etc. My memory is a bit fuzzy, but there were render-backend specific issues with MSAA, other antialiasing options, and also full screen effects in VR.
