ARFX Pro Camera Menu

Section 14. ARFX Pro Camera Menu

In the Unreal Editor you may have no doubt noticed a new drop-down menu that had been added to the main layout. From there, you will find items that include the ARFX Pro menu conveniently located in the same window, and you will not have to search for them throughout Unreal Engine. Follow the steps below to open the UI menu:                  

This menu contains multiple editor UI that are way more involved than what will be covered in this article.

This is the main tab of our ARFX Pro menu!

This menu is a simplified version of what is shown in the Details panel of a selected ARFX Camera. It will find the  first compatible camera in the scene and populate its information here. Any changes made to this menu will be reflected in the camera but not the other way round (meaning changes made in the Details menu will not be reflected on this menu). In this way, you can easily find and customize your camera for 95% of all use cases.

This menu (and all its other tabs) can be used both while in PlayInEditor !

Important

There is currently a bug in which closing Unreal Editor with this menu open will result in a blank window. Simply close the window and open the menu again to fix this.

Section 14.2 Tracking Component

The ARFX Pro menu also contains dynamic tracking component support.

Also under Camera Options, below the main section detailing the various camera settings, is the list of settings available to the tracking component. The settings listed here are determined by which tracking component is attached to your ARFX Camera.

For more information, please refer to the Tracking section of the Knowledge Base.

Section 14.3 ARFX Lens and Lens Component

The menu also supports ARFX Cameras with Lens Emulation!

If the ARFX Camera is one with LensEmulation support, then this menu will update to include settings available only to those cameras. You can find more information on the settings available within the ARFX CameraLens section.

Section 14.4 Bookmarks

The bookmarks section is your one place to find any and all your bookmarks without searching for it in your World Outline!

In the Bookmarks section, you will find a list of every ARFX Bookmark placed in your scene and all the settings available to them as shown in the Details panel. At the top of the list, you are able to do the following:

Section 14.5 Post Process Options

The Post Process Options let you edit any and all Post Process Volumes in one place!

This section allows you to modify any PPVs placed in your scene and provide all the settings available to them, as it is shown in the Details panel. At the top of the list, you are able to do the following:

• Drop-Down Menu - List of all currently found PPV, s in the scene.

When re-opening an Unreal Engine project that already had the ARFX Pro Plugin UI window open, it may show as a blank/black window. Simply close out that window and relaunch the ARFX Pro Plugin UI window from the Unreal Engine menu as described in steps 1-2 above to re-open the UI.
