New to WM- help on Build look please

Hi guys,

new here…!
I’m happy with how my landscapes are looking in the Overlay end node, but when I click Build it seems to really overly Erode or reduce the Terrain somewhat?

I’ve loaded in various other examples and this doesn’t really happen at all… they’re more or less what you see is what you get.

I’ve attached two images, one before and one after Build.

Could someone please explain where I might be going wrong as I’ve got a fairly simple setup as you can see.

Thanks for any help/advice…!

Regards,

Marc
