Universal landscape material not loading correctly in steam?

Hey guys!

So I uploaded my map to steam and everything seems to work (after hammering lots of stuff into shape, you know how it is) except for the landscape texture which reverts to grey squares.

I’m using:
https://wiki.arkmodding.net/index.php/Universal_Landscape_Material

I unpacked the files into my mod folder, relinked the MI & MM stuff for regular landscape and landscape holes, copied the primalearth/environment/landscape files to my mod folder (first I tried cooking it with everything in primalearth, which I thought should work, then when it didn’t I moved things over), pointed all my painting layerinfo stuff to files in my mod folder, and checked that when I cooked it the MI_landscape and MI_landscapeHoles were ported over to the cooked folders. They’re there, it’s just not loading.

Any ideas? I’m totally stumped at this point.
