I'm using ReShade with Black Ops II, and while effects like sharpening and colour correction work, MXAO unfortunately doesn't seem to do anything, which is a shame because I thought it would've really made the game look nice. Could someone help?
Yeah, it does look great when it works correctly.
May I ask what you mean when you say you tweak the code yourself? Do you mean you tweak the settings through the Reshade GUI, or that you manually tweak the actual shader?
Check that MXAO is enabled in ReShade. To do this, open the https://smiledatingtest.com ReShade menu by pressing the "Home" key while in-game. Look for the MXAO effect in the list and make sure the checkbox next to it is ticked.
