Hi, I'am experiencing some issues with osgPPU, (some might have been addressed before on the list):
* I use an ON_DEMAND scheme and osgPPU always has a one frame lag. (i am using a simple setup similar to examples like osgppu_viewer) * My Camera had some hud camera childs doing a POST_RENDER, these huds are no longer visible. and the previously mentioned issues * auto compute near far breaks my manipulators * viewports need a 0,0 origin I am using osgPPU to add camera effects like bloom and vignetting, the results are nice and the performance is good, now i need to resolve these issues to finalize the implementation. Any ideas if i can resolve this in my application, or are these issues to be solved in osgPPU or osg?
