Displacements /w geometry has shadows along lines

[n3dd]

Self-explanatory, I am creating a simple, just-for-looks map (for now, I aim to make a Deathrun map with this, which would have the Arena gamemode in it) and have been experimenting with displacements. I've gone towards a desert-like mountain style, and did some neat mountains. However, I've complied and noticed that the end of the displacements touching another brush gives off a shadow, as if the 'line' causes shadows. I've looked through Google, reddit and here and found no solutions regardsing this.

All the displacements have one face on each of them, there are no other faces along with them.

I am using light_environment ONLY.

(This is my first actual map I've begun working on, fyi)

I've attached two screenshots that should explain my problem.

Thank you.

From what I've learned this usually happens when they go through eachother

 

[ficool2]

Make sure you aren't compiling on fast RAD either as that also causes the problem

Complied on Normal.

Intersecting displacements will usually create such shadows. You might want to make both surfaces sew together along an edge instead of making one clip through the other.

I've tried to do this, but it doesn't allow me to 'connect' the edges together, no matter where the edges are

For displacements to sew correctly brush vertices need to be aligned with each other like this

If they are misaligned even by 1hu they will not sew:

Hm, I'll attempt to do this again tomorrow. Thanks for the advice.

This has a lot of useful info on displacements and their use.

I have managed to successfully eliminate the shadows caused by the displacements seen in the screenshot.
They appeared again in other places after using clipping tools with other brushes, which could not be fixed, but fortunately, they are not visible to players.

Once again, thanks for the help.
