Hedgehog Engine 2 - Weather

Hedgehog Engine 2 has a dynamic environment system internally referred to as “weather” that is responsible for doing things like generating a skybox at runtime or changing how materials look.

Effect on PBR materials

While the details are not exactly known right now, it’s possible to deduce several functions from reading the shaders (which, as of writing this, has only been done for Shadow Generations).

For the majority of all shaders, the following PBR properties get interpolated based on currently unknown values:

• The albedo color to itself squared
• The specular value to 0.02
• The smoothness value to 0.9
• The ambient occlusion to 1
