MXAO doesnt work with Tera Online

Hello people. I have a problem with MXAO. Looks like this feature doesnt work with Tera Online.
90% of other shaders works fine sometimes not but still changes are visible. Also Tera has no ingame msaa ssao fxaa or so on.
This game has only one similiar slider something about light. This option looks like like simple ssao but more like curves or luts.
I would like to know why MXAO has no effect. Also debug mode shows flat white image and doesnt react to slider adjustments.

Of course it doesn't. As has been explained many times before (there is a common issues thread stickied too that covers this) depth access is disabled in multiplayer games to prevent exploitation. MXAO doesn't work without it.

Excuse me. Thx for clarifying this.
