Hi,

If you are using UMG content as a HUD, it won't be visible inside Aximmetry while using Live Sync mode. However, it will work in Cooked mode.

Note, that Aximmetry has many tools to create overlay graphics and effects.
You can find some examples and solutions at:
[Tutorials]:Paint And Touch
[Tutorials]:MOS
[Common_Studio]:Compounds\LowerThird
[Common_Studio]:Compounds\Overlays

You can then connect these to the Overlays pin of the camera compounds:

Warmest regards,
