I came here from: https://forums.khronos.org/showthread.php/10207-Camera-orientation
But COLLADA 1.5 says:
The camera is defined such that the local +X axis is to the right, the lens looks towards the local -Z axis, and the top of the camera is aligned with the local +Y axis (also see the <lookat> element). This orientation is affected by the <asset> element’s <up_axis> value.
I’m confused a bit, camera element has it’s own asset element and there is a global <asset> too.
Does camera element/orientation inherit the global (document) or any parent <asset><up_axis> if <camera> doesnt have one?
