It would be nice if UE4 checkerboard texture was turned into multiple material instances, with multiple checkerboard colors, so that newcomers to UE4 can build a map using different colored checker textures.
For example, I modified the default checker to look something like this:
I then created material instances like these:
Pretty simple. 
I believe this would be a great asset to any and all newcomers to UE4. It wouldn’t take much effort to implement.
