Another attempt.
I can modify the Fresnel mask by plugging it to a Power/Multiply node and making it more effective. It works fine but it brings other problems with it.
The following scene is in First Person camera angle.
Without any modification to Specular. Notice the strong reflection on the mountains, the color information goes unseen because of it.
Killing specular using the Fresnel mask. Notice it also kills the wet mud reflection in front of the player as well. It’s easy to make the Fresnel mask distance based but it would be a per scene hack. Wouldn’t look correct all the time.
