fogMode

uniform int fogMode;

This uniform stores the fog type used for vanilla fog, based on the current biome, weather, water/lava/packed snow, etc. This is the function used to determine the strength of fog based on distance.

The value stored in each component is one of the following hardcoded integer values (see LWJGL docs):

  • GL_EXP: 2048
  • GL_EXP2 : 2049
  • GL_LINEAR: 9729
