First off, I am new to mapping and CC3, but, I have been following the video tutorials and I haven't met a major obstacle thus far. However, there is one thing that I just noticed regarding the Sheets and Effects option, my current map involves some mountains and in the tutorial it says to: "first draw the contour lines and then fade it from the sheets and effects section" using Edge Fade, inner. I think I have followed all the instructions but under the Contours (LAND) option I can not seem to add an Edge Fade, inner effect. The only options I have apart from all others is Edge Fade. This doesn't have the same affect though and no matter what I try I can't seem to make the mountain contours seem less harsh.

So I was wondering if anyone knows how I can find the Edge Fade, Inner effect?. Is it in some separate add on that I need to install or have I done something wrong?.

Thanks in advance.
