Hello,

I'm having trouble using a ImageMirror and an animated Armature in the game engine :

The mirror works well ;
The animation only runs when the mesh appears on the mirror,
when the object isn't rendered on the mirror the animation stops.

Tested with 2.70 and 2.75-rc1 with the same result.
Use right and left to rotate the mirror :
ImageMirror_Armature_BUG.blend

Thanks

Win7 64bits
NVIDIA GeForce GT 640M

Same behaviour here.

Note that if the mirror faces away from the camera, the armature moves again.

EDIT: Note 2: enabling Occlusion Culling changes the behaviour:

On Blender 2.70, fixes the problem
On Blender 2.74/75, keeps the problem, but narrows it.

EDIT 2: 2.68 works fine, 2.69 no more.

The .blend also shows a perfomance drop in armature animation due to an assert in interp_qt_qtqt at math_rotation.cpp in BLI library. This is provocated by a commit during 2.75 development (2.74 works ok).

Forget my last comment.

This comes from commit 4fac29ca0e

I add to @Moguri and @mahalin as it is related to culling behaviour
