Hey Marco,

the sphere is caused by the "Player Start"-Actor in the Unreal scene. This happens automatically andcan't be avoided, so you need to move the actor below the map or to a spot where it can't be seen. 

You can also have a look at the Introduction guide from the Aximmetry-Team, where they mention and explain all the little things to keep in mind. :)

Have a great day! :)

Best regards,

Thank you 

I've looked into the Unreal project but it seems that there isn't any "player start" between the actors

Do you think it could be something else? 

Can you share a screenshot of your unreal scene in the unreal editor, showing the position where the sphere appears in Aximmetry? Maybe also show your World Outliner, so I can see what going on.

@PozzatoMarco: It’s definitely the PlayerStart sphere! It doesn’t matter that it’s not in the scene, it will be created automatically at run time. Just follow the instructions and the problem will be solved.
