2. Enable the Environment Query System

Enable the Environment Query System as it is currently experimental.

On this page

The Environment Query System is considered Experimental, meaning it can change drastically at any time, so you must opt in to it.


  • As of 4.7 the Environment Querying System is enabled by going to Edit Menu > Editor Preferences > Experimental, and checking the check box next to Environment Querying System under the AI category.


This will eventually not be necessary, so if you don't see this check box, then you don't need to do this step.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
