I know how to UV mapping and projection mapping however, in this image, uv mapped using top projection result texture is not bleeding or stretched.

Even side faces is not stretched

I think there's another way to projection uv or another mapping? (Or decal)

I don't know how he made this.

Assuming* the topology of the wall is as it appears in your image and that it appears this way in-game, this could be first projected from an orthographic front view:

Then the UV mapping scaled, and the top face manually adjusted to minimize distortion:

*3D game assets have different design constraints than models intended for still or animated 3D art -- it's likely that the horizontal beams of that wall are not modeled in, they're from normal maps on a flat-sided wall with a rounded top, and Jachym Michal's answer shows how that was done for in-game. Also, your example image is concept art, and the top-down projections shown were likely done in 2D software (moss maps overlaying 2D images of the walls).

No projection magic, just good ol' manual unwrapping.
All texture variants follow the same rules, so one UV map works for all

  • $\begingroup$ But it's not a flat wall as your answer shows, it has a rounded made-of-logs like shape. Yet the image isn't distorted by the shape - this indicates projection (from the side IMHO, not the top) to me, assuming that's how it looks in-game instead of just in the 2D concept art. $\endgroup$

  • $\begingroup$ On later thought, looking over other images from the article ( magazine.artstation.com/2021/10/… ), that part of the walls may be flat with normal maps giving them the made-of-logs look. In which case your solution would be accurate. $\endgroup$
