  ## Disabling shaders may be necessary on some systems where Visual fails
  ## to detect that the video hardware or drivers are incapable of competently
  ## rendering the shaders used to implement certain materials.  This will
  ## revert all objects to legacy rendering regardless of what material is
  ## chosen:
  
  enable_shaders = True # Make False to disable shaders
  
  ## Alternatively, it might be possible to fix some systems by disabling
  ## only some materials, remapping them to ones that work:
  
  ##from visual_common import materials
  ##materials.rough = materials.marble
