Fog problem with a large plane

Unity Engine
1

I’m having trouble with fog on an iMac. When I try to make a bigger plane to run on, the ground takes the fog color no matter what i do. Also, scaling the plane on x and z axis (red, green) doesn’t affect the color. Only if I scale it on y-axis (yellow) it approaches the fog color as it gets larger. See attached pictures below.

This only happens on iMac (HD2600), but not on MBP (8600GT). On the iMac I also experiece some flickering while moving around in the scene if fog color is set different than from big plane’s color.

I’m running Unity Indie.

Any suggestions? :cry:

Fog is calculated at vertices, and results interpolated across the polygons. So if you have a large plane, tesselate it more.

That worked, thanks!

Though it’s still a bit of a mystery why it worked on the mbp without tesselating…
