Odd texture behaviour

Hey guys, I noticed a odd behaviour while creating a project. I created one, pretty much finished all the structures with BSPs.
Then I started to add textures. I missed the starter content so I merged it in.

But now, all BSPs before adding it only get a bunch of parallel lines when adding textures from the starter content. BSPs after adding it works fine.

Is there something I am missing?

Thanks

That’s a strange one, is it with 4.10 or the new 4.11 engine version?

Did you scale the bsp or did you select the details panel and change the size from there. That looks to be when you just scale the box and not change the size in the details panel, for some reason that sometimes makes uvs on bsp just go wack.
