Section of Landscape is Darker

I’ve been messing around with World Machine making landscapes for UE4, but I’ve gotten this weird problem. My sand texture is darker on components that are completely filled with the sand layer.

This is the part of my landscape material that I have the sand texture and layer in. (I’m using a modified version of the material from the landscape livestream.)


Can anybody tell me what I’m doing wrong?

I’m having the same issue or at least a similar one - have you found any solution to it?

Only solution I’ve found is to put a little bit of another layer where the dark spot is.

I also had the same problem. But, then I realised it was just my lighting that needs to be rebuilt. So I clicked the arrow next to build and pressed build lighting only
