How does the depth buffer look like? Enable the DisplayDepth technique to show it. If it is flipped the same way then you need to go into the settings tab and change RESHADE_DEPTH_INPUT_IS_UPSIDE_DOWN to either 1 or 0.
thk you guys... But too bad i got to turn it off because the AO is overlay to some other 3D object(pop up chat box with 3d character portrait ) which should be on top to the AO instead... Any idea to fix it btw ?
