I don't fully understand what you call artist, but It seams you don't came from the OpenGL world....osg doesn't constrain rendering pipeline..Free to you to build your own shading pipeline.
osgFX is (not perfect but) your friend for BumpMapping. For postprocess (or multiple passes shading pipeline), I never used osgPPU but read it's great for UbberFrameBuffer based deffered shading pipeline (like per pixel lighting techniques) To speak of my case, i write my own shaders, use osg::FrameBufferObject on osg::Geometry'stateset to ensure sequential passes and all works well...;) (You may direct use osg::Camera render2texture fx instead because you might not require fine grained control on multipass passes as I needed in my work) Daniel Ce wrote: > Hi, > > I am a 3d generalist, working for a lab where we make simulators.
