Hi,
what is your clearmask set to for the 2nd camera? Are the projections
the same for the 2 cameras? How about depth range?
Only other thing I can recommend is have a look at
osgUtil/RenderStage.cpp and check for search for "depthAttached". You'll
find the code and osg bitmasks you can set for controlling depth/stencil
for FBO.

folks,
i'm trying to create 2 render to texture cameras that share the same
depth and stencil buffer.
i want to render color, depth, and stencil values with the first rtt
camera and then use the resulting depth and stencil with the second rtt
camera.
this is what i'm doing:
create color texture1
create depth texture
create stencil texture
create rtt camera 1
attach color texture 1
attach depth texture
attach stencil texture
create color texture2
create rtt camera 2
attach color texture 2
attach depth texture
attach stencil texture
here's the scene graph
root
rtt camera 1
scene group 1
rtt camera 2
scene group 2
the color, depth, and stencil textures look ok coming out of camera 1,
but the depth and stencil textures after camera 2 are blank (all zero).
is this the right way to do this?
thanks,
brian
