        Hello:

        I need to build a rear view mirror for a driver simulator. To do
this, I define a separate channel for rendering rear view mirror image and
in that channel's draw callback I subload the relevant portion of the frame
buffer to the appropriate pfTexture. This works just fine on a single pipe
system. How can I share this texture across multiple pipes (CAVE)? In the
CAVE I see that the correct image is applied to a portion of the mirror
polygon residing on the front wall (I use the front wall's pipe rendering
the rear view channel), and nothing is applied to the portion of the polygon
residing for example on the left wall. Basically, the texture image is not
shared between the pipes. Please help!
