natural-mystic-shaders-1.4.0

• Fixed vanilla clouds being shown when "Fancy Graphics" is disabled.
• The scene no longer becomes unplayably dark when underwater or in
  The End.
• Moonlight no longer affects the scene on a rainy night.
• The color of the ambient light is no longer a constant white. It now
  changes depending on the terrain-dependent sunlight level and the
  time-dependent daylight level. That is, when in an occluded area
  like a cave, the only possible light sources are torches so the
  color of ambient light resembles that of torch light. Likewise, when
  on the ground of the Overworld, either the color of the sun or the
  moon will affect the ambient depending on the in-game time.
• Changed the fog type from linear fog (vanilla) to exponential
  squared fog (#12). It is slightly more expensive but produces better
  results.
• Distant terrain is now rendered with gradually reduced contrast to
  express a light scattering effect caused by particles flowing in the
  air (#5).
• Cluster of torches no longer flicker in a synchronized manner (#48).
