Chequered pattern on resource graphics

[cd5ssmffan]

My mod adds new resources to the game, however I am facing a bug which changes the textures to a red and white chequered pattern. I assume it's some kind of problem with the resource models, but I can't be sure, because this problem doesn't affect me, only some people (WTH?). I have no way to test any solutions either, since the mod works for me. Anyone know what to do? I'm stuck.

This is how the problem looks like:
