HI Sverre, The OSG-3.2 predates the shader storage buffer object extension so won't be support.
The OSG-trunk doesn't yet have support either, but it might be possible to add prior to creating the OSG-3.4 branch - and you'd be welcome to have a bash. Looking at the OpenGL extension specs: https://www.opengl.org/registry/specs/ARB/shader_storage_buffer_object.txt It looks like new enums will be needed, but most of the original buffer object setup should work. In the spec there is also use of the glMemoryBarrier that the OSG doesn't yet wrap so one might be need to look at adding this to GL2Extensions. Robert. Robert.
