Thanks for your feedback. I'm not sure this plug-in will be perfect one day
1 - Once I draw a room and click OK, I cannot edit the room anymore. After some experimentation, I found that if I move the room (now terrain) to the side, the original room is still present underneath the terrain. When I select the original room, the terrain appears and I can edit it.
The idea is that if the terrain is incorrect, you wouldn't want to keep it and probably delete it. Therefore, the data about elevated points is stored in the room(s) which were used to generate the terrain and should be selected to generate a modified terrain.2 - The difference between Magnetism ON and OFF is that we get the old spikes, or the new more gradual elevations.
When magnetism is off, only the elevation of the dragged point is changed. It's useful if you want to adjust the elevation of one point. With this idea in mind, I'm not sure to understand your issue with spikes, even if "magnetism" should be maybe renamed as "smooth".3 - It is not clear to me what Alignment does, or how to switch it on/off.
4 - I cannot reproduce the action in the second image, where it seems the whole width of the terrain is raised.
Alignment is activated with the Shift key and makes the points around the dragged point more or less elevated along all the current horizontal axis.4 - I cannot reproduce the action in the second image, where it seems the whole width of the terrain is raised.
5 - Maybe it's a nice idea to generate the terrain in a new level at the same height.
Create a level at same elevation first before using the plug-in. The terrain object will be added to the selected level.----------------------------------------
