How do I know if my Asset is an “Extension Asset” which requires a Per-Seat license?


  • I am about to submit an Asset and would like to know about the ‘Extension Asset’ category.
  • I need to know if my Asset submission falls in the ‘Extension Asset’ category.


When you submit your Asset, you are able to choose its category.

Depending on the type of Asset you are submitting, some categories may not appear.


If your Asset is an editor extension, scripting tool or a service, then your package will fall into the ‘Extension Asset’ category. 

An “Editor Extension” is a package that allows the user to extend the editor with custom inspectors and Editor Windows and you can define how properties are displayed in the inspector with custom Property Drawers.

“Scripting”, is a tool within the unity editor which assists you in developing your scripts. E.g. ‘Playmaker’ is a visual scripting tool and would fall into this category. 

A “Service”, is anything that’s integrated but delivered as a separate service on top of the engine. Services are used to engage, retain and monetize audiences.

If your package falls into any of these categories then your Asset is defined as an ‘Extension Asset’ and will require one license per seat.

    Unity, please don't allow per seat licenses on assets that need to be committed to source control. Since you don't offer any way to track license this makes it very hard for enterprise customers to deal with this.
