If you added a plugin from the marketplace, you should go to “Content Browser” and select “Show Engine Content”.

In “MyActor” you can find the “Multiplication by number” section in which you can control the scale of the movement of the camera/object by increasing or decreasing the multiplier, the value of “1000” is 1: 1.

In the “Multiplication by number” section you can control your coordinates “Movement” and “Rotation”. Also, you can turn on and turn off all coordinates if you need.

In the “Body” section you can find “Auto Focus”. Also, you can turn it on and turn it off.

In the stabilization section, you can change the stabilization strength. For sensitive camera operation, select 0.5, and for very smooth operation, select 1.

In the “ARPhone/Bode” section you can control “Camera Follow” – mark it if you want to work with a virtual camera and unmark if you want to work with a virtual joystick, mark and unmark “Debug Message” and choose a camera to display, it can be “Cinematic Camera” (you should add it to the scene before choosing).

Only for Joystick mode! If you want to use Joystick mode and move an object in your scene, you just need to add any “Mesh” to the blueprint and unmark the camera following the “Actor” settings. Add a new “Component” in your Blueprint.

Solutions for some popular problems while using Plugin

1. If you are sure, that the network, PC, and mobiles are working well but you still have problems – this may help you:

Windows panel -> Settings -> Network&Internet -> Wi-Fi -> Windows Firewall and turn the firewall off, sometimes it can block data transfer on port 7777

You can also choose any other free port for data transfer, in this case, you will need to change them both in the application and the plugin settings in the “Network” section.

2. If video streaming does not cover all screens on the phone or instead It cuts some part of the viewport – change the play mode to “New Editor Window” on the top toolbar or try to adjust the viewport size.

3. If you have a connection issue use not loaded access point to fix the problem, the problem can be if you work in a place with a lot of devices on one router.

4. If you want to use VR mode – enable “Google VR plugin” and disable “Steam VR” because it can block video streaming.

5. Turn off “RTX” when you use “VR mode” If you will not do it you will get problems with the screen rendering and your phone will have one black window on one of the VR sides.

6. If you want to build your project you need to turn off UI (MyActor->Details panel->User Interface->”Enable GUI”) in “MyActor”, otherwise you will get an error launching your project’s Exe.

7. If you have an error like this when you run the project “CheckForFirewall.exe”: Go to MyActor on the scene->Details->ARPhone-> Network-> and untick “Turn off windows defender”

8. UI during render does not affect the final result of render.

9. Video panel in the sequencer becomes hidden because of incorrect tab switching. You can fix this issue in two ways:
-Close the Take Recorder panel and open it again.
-In the viewport in the left upper corner choose the tab ‘Perspective’. Choose ‘Viewport type’ – ‘Default’, then again ‘Cinematic’.

10. If the application is connected, the interface buttons are active, but the tracking does not occur, then check and set the permissions to use the camera in your mobile phone for the Virtual App application.
