Hi Brian, yes, you need to disable the OpenGL color value clamping. This can be done by this, I think:
Code: // disable color clamping, because we want to work on real hdr values osg::ClampColor* clamp = new osg::ClampColor(); clamp->setClampVertexColor(GL_FALSE); clamp->setClampFragmentColor(GL_FALSE); clamp->setClampReadColor(GL_FALSE); // make it protected and override, so that it is done for the whole rendering pipeline node->getOrCreateStateSet()->setAttribute(clamp, osg::StateAttribute:ShockedN | osg::StateAttribute::OVERRIDE | osg::StateAttribute::PROTECTED); cheers, art Brian R Hill wrote: > Folks, > > I've been working with the osgscreencapature example to use pbuffers for > offscreen rendering.
