Hi,

First, you need to cook the Unreal project in Unreal Editor for Aximmetry. You can find more information on how to cook the project here: https://aximmetry.com/learn/virtual-production-workflow/preparation-of-the-production-environment-phase-i/obtaining-graphics-and-virtual-assets/creating-content/creating-content-for-aximmetry-de/preparing-the-unreal-project/ 

Warmest regards,
