Hello, I'm having a very strange issue as I start to style my map. I've broken up the wall on one side of my chamber so I can apply different textures to different regions of tiles but as I began rebuilding this wall, the texture from the corner piece has spread all over the touching faces of the other brushes. Compare how it looks in hammer to in engine here:

If I move the corner piece, all the textures behave correctly, but what ever the front texture is of the block in the same position as the selected one in the Hammer screenshot, appears over the faces of all the blocks.

To answer my own question.. it seemed to have something to do with the way the compiler was 'optimizing' the faces which were all the same size and then combining them in to one. As soon as I adjusted the dimentions of the blocks to be different, the effect above stopped happening.

Bizarre. Thanks for following up with the solution though.

Could you post your compile log? I'm really curious about this. I have never had this happen.

Have you done any manual vertex editing?

Sadly, now that I've fixed the problem, I'm not sure how to recreate it! I had a slightly older version of the level which I've tried to reproduce the bug on but I can't seem to get it to do it again!

And no, I curren't haven't even learnt how to use that tool! All brushes are either new or clipped. The only strange thing I've done is a bit of displacement to another nearby brush, but after turning those off with VisGroups, the issue remained until I made the change listed above.

Yeah that is shockingly weird. I'm glad it's fixed but I wish I knew the cause. I assume your map didn't have any leaks or anything? Did you carve anything? There was another map posted here recently that had a similar though very different issue. The problem there was the guy carved a ton, and it made a lot of off-grid brush faces and caused the section of a brush face to extend past where the brush actually was.
