Why is there a random seam showing after compiling my map?

I've made sure there are no leaks, no brushes that line up with the seam that shows from the front to back to top to bottom, remade the nearby brushes completely and nothing seems to fix the problem. This is a rounded surface made using the arch tool. It's 1/4 of a circle and has 8 sides on it, none of which match up to where the seam appears. All of my brushes in the map are also 100% lined up to the grid.

Here's a screenshot of the problem in game:


Here's what I see in hammer:


This problem didn't start until the last few versions of my map. I've done some research and think it might be related to area portals, but I can't find the "Load Portal File" option in my Map menu. The only thing I haven't tried is making my own area portals.

Any idea what this issue is and possibly how to fix it? I had another one on my map on a texture I had used the vertex tool on but had another copy of the same texture so I deleted the one that didn't work and made a copy of the one that did and that fixed the issue there, but I feel like I've exhausted everything I know how to try to fix this.

I should also mention that I have this issue even when testing with VIS and RAD turned off.

Are the vertices themselves on the grid? It looks like a floating point error.

I don't have any vertices nearby. The arch points themselves do not line up with the grid but they never do with this many points. Also, I have 5 other arches like this in my map that work without issue.

I got half of the issue fixed. Now it's just the bottom portion of this brush that has a tear in it and it seems to be about half as wide of a tear:

Take the grid down to 1-unit size and snap your vertices to that. Floating point errors are rare but if your vertices are on an integer coordinates this should never happen.

Sorry, I double checked and verified all points are snapped to the grid on my arches. I do have a platform on the inside of the arch that I clipped to match the points on the inner side of the arch but they all match up perfectly as well. So the only other things on my map that don't match to the grid are props and some of the pillars I made where it'd be impossible to make each side fit to the grid. Still, these items aren't attached to the wall with the problem and are not on the same grid line. The pillars are also func_details.

This is a problem on spiderx as well, but I did find a solution which I was too lazy to fix at the time. If you remake the brush (can't remember if you can just copy paste from another source) it should fix it.

side note

not related to your exact post but,

If you don't run lighting (vrad) I don't think your map will detect a leak and a pointfile would not be created. Try Neon's idea, delete the brush and remake it.... Make sure its all on grid ( I think the arch tool puts all your points on grid) and see if that works.

p.s. Hammer always does some weird shit that makes no sense all of the sudden. good luck

and when I reread it you said areaportals and not pointfiles.... I dont think your map needs areaportals unless your fps is really dropping low but I doubt with what I've seen of your map its necessary (or would work with the layout). It would give you errors during compile if it was areaportals and I dont think it would cause the tearing effect you have.

I've run a full compile with RAD and VIS turned on, still with no leaks or point file. I made sure to get rid of all my leaks before I tried to fix this tearing issue.

Neon, I did try copying/pasting from another source with no luck. I'll try making a brand new arch and see if that helps.

fixed finally. I set all my curved corners to func_details and no more problem.
