Strange Missing Textures On Landscapes

As far as I’m aware, I’ve applied the material and set the layer info, then pointed it to a raw image file upon creating a landscape actor.

Which files from the project would you need? That might be the simplest thing to do.

I’ll try to explain as best I can what process I took to get to these results, though.
First thing, I imported a few texture sets, by that I mean albedo, normals, etc for each texture imported, like mud or grass.
I put those into a material and hooked up all the UVs for each texture to a landscape coordinate node, set to 5 for the scaling in the coordinate node.
After separating them into each texture type, albedo with albedo and so on, I hooked up each, for instance, albedo to a landscape layer blend node, set to LB alpha blend and 1 for the preview blend.
Then I hooked up the output of the blend node to each material channel, let it compile shaders, and those kind of results showed up.

I’ve also had, when messing about a bit, completely black images on the landscape, not just spotty texturing. As best I can tell from my debugging, it seems like that at least comes from the blend node, although why, I’m not sure.
I mention that just in case it has some bearing on the issue at hand.

Hopefully that explains things a bit. If not, though, just let me know what files you need and I’ll get them to you. =-)
