After inspecting the OpenSG code more carefully I must say that many multisampling things are already at the right place :-). What I did not find was the texture image generation for multisampling. I think that serious work has to be done in files System/Depreciated/State/OSGTextureChunk.cpp System/State/Base/OSGTextureObjChunk.cpp, some additions (GL_TEXTURE_2D_MULTISAMPLE,GL_TEXTURE_2D_ARRAY_MULTISAMPLE) are required in: System/Window/FrameBufferObjects/OSGLayeredTextureBuffer.cpp System/Window/FrameBufferObjects/OSGTextureBuffer.cpp I do not know what is necessary for these two System/Window/Background/OSGTextureGrabBackground.cpp System/Window/Foreground/OSGTextureGrabForeground.cpp and what I also do not have understood if the following files work in case of a multisampling render context: System/NodeCores/Groups/Effects/Projectors/OSGFishEyeProjector.cpp System/NodeCores/Groups/Effects/ShadowStage/OSGDitherShadowMapHandler.cpp System/NodeCores/Groups/Effects/ShadowStage/OSGPCF2ShadowMapHandler.cpp System/NodeCores/Groups/Effects/ShadowStage/OSGPCFShadowMapHandler.cpp System/NodeCores/Groups/Effects/ShadowStage/OSGPerspectiveShadowMapHandler.cpp System/NodeCores/Groups/Effects/ShadowStage/OSGShadowStage.cpp System/NodeCores/Groups/Effects/ShadowStage/OSGShadowTreeHandler.cpp System/NodeCores/Groups/Effects/ShadowStage/OSGStdShadowMapHandler.cpp System/NodeCores/Groups/Effects/ShadowStage/OSGVarianceShadowMapHandler.cpp System/NodeCores/Groups/Light/Shadow/Engines/OSGShaderShadowMapEngine.cpp System/NodeCores/Groups/Light/Shadow/Engines/OSGSimpleShadowMapEngine.cpp Once again sorry.
