Within a render callback such as OnWillRenderObject, it's useful to be able to check which camera is rendering. Unity has "Camera.current" for this, but it's not exposed to Udon.
The new camera API is awesome, but without a property like that, I still can't make my UdonPortals prefab render correctly in the hand-held camera because there's no way to tell which camera is currently triggering OnWillRenderObject.
I'd like a property to tell which camera is responsible for the render. A really simple implementation would be a new read-only property like:
  • VRCCameraSettings.CurrentCameraType: An enum consisting of the values "ScreenCamera" or "PhotoCamera".
However, I think this API could be extended further to be even more useful. In particular, if a Camera that was created by the world (and so is already accessible to Udon) is rendering, it would be great to be able to access the actual Camera object! Just like Unity's "Camera.current", but only limited to world-created Cameras. An API might look like this:
  • VRCCameraSettings.CurrentCameraType: Enum consisting of the values "ScreenCamera", "PhotoCamera", "WorldCamera", or "Other". "WorldCamera" would be any camera created by the current world, i.e. a Camera that's accessible to Udon. "Other" would be anything else that isn't (yet!) accessible to Udon, e.g. avatar cameras or the screenshot camera.
  • VRCCameraSettings.CurrentCamera: A reference to the current Camera object, just like Unity's Camera.current, except it's only set when CurrentCameraType is "WorldCamera". Otherwise, it's null.
