I created a terrain, following the steps I learned from YouTube tutorials. I then created a very simple house to put on the terrain (a hill). I moved the house to hover above the hill, then I used the Stamp tool to make a place for the house on the terrain. After that, I moved the house to sit on top of the stamp in the terrain.
The problem is that when I used the Orbit tool to change the angle of view, the stamped portion of the terrain moved out of its location on the terrain! When I Orbited to the right, the stamped terrain moved off the rest of the terrain to the left. When I Orbited to the left, the stamped terrain moved off the rest of the terrain to the right! So it was not in a single location in the model, but Orbit was actually moving it around! (I wish I had saved some screen captures of this…)
To get around this, I copied the stamped terrain to the clipboard as a group, then deleted the original. After that, I pasted the stamped terrain and moved it to where it belonged. After that Orbit worked as expected and I could view the house on the hill from any perspective and see what I expected.
Can anyone explain this behavior? Or is it the bug that it seems to be?
