Material Shows Solid Color (NOT UV RELATED?!?)

[AugmentedSmurf]

So, I started creating a house in Blender, and exported to Unreal to see the scale and such, but for some reason, my roof tiles material for this one specific set of faces is not showing up.

My material is set up alright, because it works on that other little bit on the side of the house:

I’m no stranger to unwrapping UVs and making sure they work properly within engine. In fact, that’s one of the things I rather like doing. And obviously the other parts work fine. Just this roof bit is giving me trouble. I even tried switching to the brick texture, and this is all I got:

I’m truly at a loss here. Anyone have any ides to look at?

It does really look like a UV problem. Can you show the UVs for channel 0?

[AugmentedSmurf]

Huh… Looks like I have Channels 0, 1, and 2. And all my UVs are on Channel 1. What do I do with this information?

I figured it out. I had to go into the mesh settings in Blender (the little green triangle), and delete the UV map that was causing the issue. Once I did that and exported it, it worked absolutely fine.
