[osg-users] Reuse of shadow textures and other RTT between two slave cameras

[OpenSceneGraph Users]

Hi.
For context I'm developing a VR solution for the OpenMW project.
To achieve stereo view i'm using two slave cameras.

To avoid a redundant traversal of the scene graph and the associated performance hit, it would be beneficial to reuse shadow textures computed based on the total FOV of both cameras, rather than completely redo shadows on both eyes.

Any advice on how this could be achieved with osg?
