Dear OpenSG user, I'm going further in my investigation in the version 2.0 of OpenSG and struggled into a strange behavior.
I'm compiling the "testSHLEarth.cpp" test, but when executing it I get only the background. Can't see at all the sphere (earth). All shaders compile fine, without warnings, and images are correctly loaded. GDebugger confirms this and catches no OpenGL errors. Only console warnings I get are regarding NVidia extensions: I have an ATI Mobility Radeon HD 4670: WARNING: Window::getFunctionByName: Couldn't get function 'glCombinerParameterfv NV' for Window 0000000002FD7D80. WARNING: Window::getFunctionByName: Couldn't get function 'glCombinerStageParame terfvNV' for Window 0000000002FD7D80.

WARNING: Window::getFunctionByName: Couldn't get function 'glFinalCombinerInputN V' for Window 0000000002FD7D80. WARNING: SimpleSHLChunk: link status: Fragment shader(s) linked, vertex shader(s ) linked. blue loaded WARNING: SimpleSHLChunk: link status: Fragment shader(s) linked, vertex shader(s ) linked. red loaded WARNING: SimpleSHLChunk: link status: Fragment shader(s) linked, vertex shader(s ) linked. Press any key to continue . . Removing the shader chunk the earth comes back. I have no clue of what is happening; also tested creating a very basic shader writing only glFragColor with a very simple material attached to a sphere. Again the geometry disappears and can only see the background. My current OpenSG2 revision is 2511 (64bit), compiled on Windows7 64bit. Any ideas?
