{F235720}Go prone with a Fireaxe in your hands(or even nothing in your hands), press right mouse button to rise the fireaxe or hands and look at ground, the character will have half body trough the texture. You can glitch trough like this in every texture. With any guns in your hands it's not gonna work like this(you can't see trough texture)but can be seen your gun.

This is what you see doing that on any roads of the map.
