Got a big plane, sculpted some hills, put a displacement modifier on the plane, the coordinates are a uv map for just the hills. Now there is these nasty artifacts at the borders of the whole thing. Also notice how high the strength is, usually you have to set it lower than 1.
Is there an easy workaround to get rid of the artifacts or do I need to sculpt it?
What is the reason for the high strength of the modifier to see results of the displacement?
The sculpted hill. The selection is the uv map which the modifier gets applied to. (one won't see the back of it)
The displacement map. Don't worry about the upper part it's from a hill somewhere else.
