Texture with extreme tiling is missing from build

I have this weird model (I made it in sketchup years ago) where the material tiling has to be ridiculous to look good (5e-06, 5e-06). This has always worked ok in editor but a build seems to remove it altogether like it is just the default texture (the preview in editor shows this too actually but it works on the model in editor which has scale factor 0.001). Anyone know how I can get the material to work in the build? I could cover it in planes I guess but it seems like a pain

edit: seems the problem is possibly "one of the triangles is too large", Im guessing I could fix in blender or something.
