Hi Chris, if you are looking for raytracing osg scenes in general and not OptiX specifically, you could also have a look at https://github.com/szellmann/visionaray There is a visionaray plugin for OpenCOVER which is our OpenSceneGraph based renderer. You find it here: https://github.com/hlrs-vis/covise
