Hey guys. when there is a lot of parallel lines in model, such as steps, steps flash when be observed from long distance.
the graphic below is when observed from short distance.
If it is texture flashes, Mip-map function in UE4 can perfectly solve the issue. But it is model flashes, I do not know how to solve it. When I observe from middle and long distance, the steps flash so obviously that attracts my attention immediately, but that’s wrong effect in architecture.
