UE4 RnD – Tiling Solutions

Due to the nature of the environment it was clear that I would have large flat featureless planes. This introduced the issue of tiling.

Solution 2

Another approach was to overlay the same texture several times on its self. The material below has been stretched over a kilometer and supports details as small as a few centimeters while still showing some variations from a great distance.
