When I replace one mesh over another whith the same Yaw value, some artefacts appears. How can hide it?
Can’t you just add a bit to the Z location? Even 0.0001 should be enough.
Better solution, don’t le’t them overlap.
I tried this solution, but when I buid light, shadows appears on nearby meshes that are lower than current.
Can you offer how to place meshes close to each other?
I found answer for my self. Now I use Vertex Snapping! Learn more here https://docs.unrealengine.com/latest/INT/Engine/Actors/Transform/
