Hi,
I'm working on a terrain texture for Unity made with multiple tiles of microscopic images of mold.
It's one big image split into four 4096px images.


I successfuly generated the UV maps from my images in Substance Alchemist.
The problem is that the calculated heightmaps don't fit in the edges, where they're supposed to tile.
How can I get my images heightmaps to tile?

Thanks, have a great day!
