hm, unfortunately that did not help me a lot. However, after looking at
more OpenGL logs from running the program I think there might be a
problem with the states set on the chunks of the ChunkOverrideGroup,
e.g. near the end of Voxelization::discretize() there is
stencilCh->setStencilFunc(GL_NEVER) which will prevent rendering to the
colour buffers because the stencil test never passes.
Can you double check the state changes you make match the algorithm you
are implementing and compare with the OpenGL logs if they set the
correct state? I don't know what the passes you are rendering need to do
exactly, so this is difficult for me to check.
Cheers,
Carsten
