look at the last line of the image, you have to pass in 0 to 1 and then also add the following line

TERRAIN_SHADOWS_RECEIVE = 1

Doesn't work for me.

you should have marked tessellation and marked in shades according to the image

I did it exactly as you described.

Doesn't work.

I regret that no answer which video card you have, maybe it's that. only guesses

GTX 560Ti.

I doubt the cards is the problem.

Doesn't work for me either. Perhaps that's one of the reasons that it's not an official feature yet.

I discovered that only work on view outside the plane, turn around and see if the have

I was trying. And nothing.

I really want this to work any more details?

I've done what you post anything else, not know because my computer works and not others.

Can you please try the cloud shadow with 'overcast' sky? All lands will be darken then?

Here is the "real deal" straight from LM: http://www.prepar3d.com/forum-5/?mingleforumaction=viewtopic&t=4178

 

"Cloud shadows aren't officially a feature yet. We just forgot to prevent that value from writing out to the config. We got clouds rendering into our shadow maps but did not have time to make a way to flag them as clouds and do something special with them such as blur and lighten them. They aren't very usable in the current state so we decided to hold off for a point release.

"Steveli: You can get cloud shadows as described above, but they aren't going to look great (also as described and pictured above). I was just letting everyone know that we didn't intend for people to be using them in their current state. We'll be adding official cloud shadow support in a future update. If you want to try using them in their current state, feel free. Just be aware that they are in an very rough beta state right now.

Hope this clarifies a bit.
