Hello,
I'm attempting to learn the terrain modelling techniques to best map my current landscape/terrain before embarking on modelling the existing house (I've placed a simple building to give context only).
To learn what works and doesn't, especially with terrain breaks and retaining works, I've selected the lowest terrain specification options ( LOW Triangle Count and LOW Terrain Smoothing). This works well and 3D camera views are great.
Whenever I attempt to increase the Triangle Count to MED or HIGH this seems to break things (introduces strange 3D artefacts) and the 3D camera view has extreme high and low elevation points. It also seems to introduce numerous contour lines near the terrain boundary that relate to these spikes and troughs.
These pictures show the settings and what I've tried to describe.
