EDIT: This is for In game Terraforming, kind of like in life is feudal. https://www.google.com/search?q=life+is+feudal+terraforming&rlz=1C1CHBF_enUS792US792&source=lnms&tbm=isch&sa=X&ved=0ahUKEwj73bS6lo7bAhUHzoMKHYlWBhoQ_AUICygC&biw=1920&bih=949
Ediiting pixels vertically makes a line, but horizontally makes a peak the edited terrain pixels are adjacent. The height map resolution is 513.
When I turn on shaded wireframe in scene view, the issue becomes clearer. When the terrain is tessellated, each vertex/terrain pixel is part of 6 edges. I suppose to fix this issue I would need to double the triangles, having each vertex be part of 8 edges.
What, if any, method could I use to achieve this and rid this behavior?
