Combining/sewing pieces of terrain/landscape?

Alright, so I have multiple pieces of terrain, and I need to find some way to either combine them or have each edge’s height match the adjacent tiles (see picture). Is there a button that does this automatically? Thanks for the help in advance!

I’m not aware of that kind button but if you are skilled enough you could extend terrain tools to do edge sewing… If you need some inspiration how to do it search for Unity terrain tools I think there is function that does that. In principle it should be the same.

Yes you would just use ‘world composition’ which now in 2018 works wonderfully.
Stitching takes place, usually very well, automagically long as your files are named correctly and you set things up right.

I’ve done this successfully and am very happy with results .

Let me know if you need more help. ( IF you are still here…)

Good God, I need help with this. My terrain is not showing up in the World Composition

Yeah, I had world comp on which is weird. What I ended up doing was exporting the terrain as a height map, and adding extra area using paint brush tool in photoshop and by stitching together different height maps

Sorry I didn’t know about this 6 days ago, missed it in my mail app here in windows 10,I SO need to find something else as this thing doesn’t filter! ;0-

Any pics would be good, but are you sure you enabled worldcomp , without that it won’t work- I presume so just making sure.
What steps have you taken so far so I know how to help.
