Why does my imported WorldCreator2 landscape have "cracks"/"seams" between each quadrant?

I have no idea if it was out of order because nothing matched up! lol
I had the cracks at the seams like yours does.
I decided workflow for me would be cleaner to keep everything default in World Machine and then flip Y while importing and that fixed it.
I’ll give World Creator a go and see what happens.
OK I can’t do that. I thought it was freeware.
