The Retro Skybox shader works similar to the built-in Skybox (Cubemap) shader, except it supports lowered resolutions and restricted color depth. You can also overlay a procedurally-generated cloud texture.

Retro Properties

  • Base Color - The base color of the sky.
  • Base Texture - A cubemap texture containing the sky colors.
  • Resolution Limit - Sets an upper bound on the resolution of Base Texture.
  • Color Depth - How many possible color values can exist per channel. Typically, the maximum for a PNG image would be 256.
  • Color Depth Offset - Adds a small offset to prevent color darkening, which is common when reducing the color depth. The 0 to 1 range of this parameter represents an addition of 0 to 1/(color depth) to the output color.
  • Use Point Filtering - When enabled, the texture uses nearest neighbor filtering, which looks blockier than bilinear filtering.
