Fog issues

While I have fog enabled, as I turn my ground plane goes from dark to bright.
Any body know what might be causing this?:spin:

Fog in the BGE is Vertex-based. That means the Fog-color is calculated for the vertices (relative to the camera). The face color is an interpolation between the involved vertices (3 or 4).

The conclusion:

  • Fog does doe not look good on large faces.
  • Fog does not look good when using faces with very different sizes.

It might be better with GLSL-mode. But I do not know that.

Yeah, subdivide that plane a couple of times, it’ll look way better.

I think fog works off pixels instead of vertices in GLSL… So Monster’s right?
