Custom 3D Flattern problem

[Davide Ferrara]

Hi,
I'm trying to place a custom terrain mesh over a default mountain so to merge my custom mesh I've made a custom flattern and exported as FSX FLATTERN with MCX.
The problem is when I open p3d I get this visual error.

This is my mesh exported as flattern

this is on p3d:

I need my custom mesh to place my 3d model over it, even if I make a custom flattern with ade I have this problem, any help would be appreciated. Thanks.

Hi,

In the top down view it's hard to see what's wrong with the flatten. What is the problem?

Hi,
If I place the custom flattern made with mcx I see the terrain over the see, in the second photo you can see there is a square of terrain where should be water...

What's the altitude of your flatten? It's not weird that the scenery engine draws land in where the altitude is bigger than zero.

So flatterns altitude must be 0?
Then how can I change the shape of a mountain to adapt my 3d model?

But if you want a mountain why is it a problem that land appears? Maybe you can explain what you try to achieve.

I'm trying to place this mesh over the terrain without having holes on the side, maybe is better if I put down the vertices of my 3d mesh instead of modify the p3d terrain...
