RR with animated fog (no shaders)

I know it’s not as peachy as it could be with shaders, but the shader generator failed me (for the first time), the post-process filter available on the forum is not very good and I’m totally, utterly useless when it comes to shaders.

Download, run, judge for yourself. Or don’t.

Here’s a new and silly way to do fog:

Works with the autoshader with shadows, looks not-that-bad, and that was the goal.

I think you can’t tell the difference.
Actually I think this might even look better because of how real fog works, which can cause things to be seen by looking straight at it and then looking a bit away, because of FOV.
