The 1.35 update now has native support for Steam Input in addition to the platform specific input mechanisms we already supported (e.g. DirectInput, XInput, evdev). The Steam Input applies primarily to the Steam Controller where the existing support was not ideal however it is possible to use it for classical controllers (Xbox, PS4, Switch Pro) and take advantage of extended configuration features the Steam Input provides (e.g ability to bind a different actions to short and long press of a button).

The Steam Controllers are always using the Steam Input. For each type of classical controller you can decide if you want to handle that type using the Steam Input or use our normal configuration support by opting the controller type in or out of the Steam Input support. A controller type can be opted into the Steam Input using the Controller Settings screen in the Steam client. This screen can be opened from the main menu of the Steam client by selecting Settings > Controller > General Controller Settings button. On this screen you can check or uncheck checkboxes corresponding to types of the classical controllers you want to opt in or out the Steam Input support. Please note the Generic Gamepad Configuration Support choice on the Controller Settings screen corresponds DirectInput devices and you might not want to enable it if you are using a non-gamepad controller such as a driving wheel.

If classical controller is opted into the Steam Input, it becomes unavailable on the in-game controllers screen and all its configuration must be done using the Steam Controller configuration UI. So if you are missing a controller there, please ensure that you did not opt it in in the past.

The Steam Controller configuration UI is only accessible from the Steam Big Picture in-game overlay. The Steam will use this type of overlay if the Steam client itself is running in the Big Picture mode or if Steam Input enabled controller is used. To access the configuration UI select the Controller Configuration choice in the overlay menu. If you did not configure the controller yet or have a configuration created for older version of the game, the best initial step is to apply official SCS configuration and modify it as necessary. To apply a configuration on the Controller Configuration select Browse Configs, go to the Recommended tab, select the configuration named Official Configuration for Euro Truck Simulator 2 and on the configuration preview screen select Apply Configuration.

Please note that when applying configuration which contains large changes, like it happened during the update to 1.35 or after some updates of Steam client, the binding configured in the UI might not work in the game. In that situation the game.log.txt will frequently contain messages such as [steam] Failed to resolve action set. The best way to solve this situation is to restart the Steam Client.
