Growth mode will have the wrong initial position

[LYB]

Hi,
I try to import a terrain polygon. I want the trunk to grow on it and be oriented horizontally. Everything is set very well. However, when I turn on Growth, the position of the trunk appears in the wrong place.

Is there a solution?

thanks

Here is the terrain fbx and file

Hello LYB

There seems to be a problem with growth and zones, we're looking into it!
