Folks, Sorry for another post on this subject. I just can't figure out how to disable the clamping of the output. I'm want to render offscreen without a window with 32 bit floats.
Attached is the sample code I'm working with, it's based on the osgscreencapture.cpp example. It uses a shader to write an input uniform float "val" to the pbuffer. The "val" varies from -1.0 ... 2.0. Any help would be appreciated. Thanks, Brian (See attached file: offscreenrender.cpp)
