I have a shader using landscape-blending to blend 7 materials using height-masks. The material also uses height-based tessellation. Lately when i paint on my landscape Unreal Engine freezes for 1-2 seconds when I release the “paint-button”. I have checked my computer performance during the lag-spikes and it does not seem to be a performance issue. No “performance spikes” when the error occurs. It would not be a problem except that I have to paint a very large landscape. Those seconds will add up. Does anyone have a solution?
Tried on a smaller square landscape and did not have this problem.
