Vertices move after Save

I’m having a problem with Vertices moving after a save in CSGO Authoring Tools.

( I re-sized the screenshots because didn’t know if theres a rule about having 1920x1080)

I have tried the following with no success:

-Selected all brushes and made into:

-Copied and Pasted to new Map file

-Recreated the brushes

-Tried Cutting the brushes into Triangles(Didn’t work because the cut tool cuts off a piece of the brush even though the cut tool was set to save the brushes, it just shows 2 white sections and a small red piece that gets cut off)(Tophatwaffle Video solution didnt have a slant)

-I even tried converting the VMF into a model with the process that comes with it, but the new model has the vertices still moved because of the saved file.

-I tried using the Batch compiler thinking maybe it was breaking during compile but no success.

-I Copied and Pasted the map to L4D2 Authoring tools and well the same problem happens.

-I tried looking up the problem online not much answers

I tried asking my amazing mapper friend mopman who knows everything but he didn’t know either.

Some might say I should just forget about it but to be honest its needed for detail and well the map looks boxy with out it :D.

I believe this is the best place to ask a question about mapping problems.


It’s probably an invalid brush being fixed automatically. Go into vertex mode, select two vertices and hit ctrl+f. This splits the face into two triangles and should prevent it from being changed upon save.

Could you show us what it looks like in the viewports?

Oh wow never mind I guess I failed at understanding on how to use the ctrl + f and well it worked! Thank you so much FelixDragon
