Any time in game, just press SHARE+OPTIONS(PS4 platform)keys on your controller to enter CONFIG MODE and the LOGO’s light will be turned off in this mode.
Then, you should press the PS key (PS4/PS3) or GUIDE key (XBOX ONE/360). Then the LOGO will show flashing blue. This means you can choose one key on the controller to be mapped.
Once the key on the controller is pressed, LOGO will show a stable blue light, and then wait for the corresponding key on the keyboard, mouse, joystick, etc. After selecting your key, Cross Hair will keep flashing blue again. Then a new key mapping can be continued.
Just like the general key’s mapping, if you are planning to use keys on keyboard or mouse to replace stick on controller, push the stick to its maximum on one direction (such as Up direction), LOGO will show a stable blue light, and then wait for the corresponding key on the keyboard, mouse, etc. After selecting your key, Cross Hair will keep flashing blue again. Then you can continue to map a new direction of this stick.
After mapping all the keys, you can press SHARE+OPTIONS(PS4 platform)keys on your controller to exit the CONFIG MODE, and end the mapping procedure.
