Terraforming problem

Any kind of terraforming, be it a Polygon, a Rectangle or a Runway profile, doesn't update in the Scenery Editor anymore. When moving the Gizmo to change the altitude, the terrain doesn't raise, but auto-generate GRASS does.

I reported the problem on the Feedback Hub too...

Hello virtuali.

Thank you for reporting this.
The fix will not make it into SU6 unfortunately but we were able to reproduce it and know how to fix it.
As a workaround, zooming out and zooming in will force the refresh of the LODs and you should have the correct terraforming displayed then.

Hi Sylvain,

Will we expect SU7 fix for this? Thanks!

Let's consider this half of a workaround, since zooming back and forth produces also holes in the scenery, and other weird artifacts :)

Also, this seems to influence Heightmaps Rectangles too

Another thing worth noticing. While editing in DevMode the terrain, if this problem is present, is uneditable sometimes, and tends to be unconsistent to a compiled and installed in the Community folder counterpart.

I'm experiencing a lot of small hills and holes which disappear once installed and launched.

Hope you guys can look into it :)

Another thing worth mentioning is that I'm deep into the heart of the development of this scenery which already counts a lot of working time, so dozens of aprons, polygons, terraforming rectangles, custom assets and so on. But this has happened only after the latest updates before SU6 :)

Yes, in fact, this seems to be a refreshing issue, as moving over the area display progressively the correct heights.
