Navigation Memory - What is it? Can I claim it back?

Hey all… Quick Q… when i run the console ‘stat memory’ I am seeing 225MB allocation for Navigation Memory.

As I don’t have any characters or AI (hardly anything moving for that matter), is there a way of disabling the Navigation System? I’ve had a look at the Navigation settings within World Settings but nothing seems to remove that 225mb.

I don’t have any Nav Mesh Volumes or similar in my map.

As I’m targeting Console platform, i’d prefer this memory to be available for other things.

Best Regards,
Matt.

Just a quick bump before I let this Q die… anyone have any thoughts?

Hi, i think it is collision memory or, check this setting on your world settings

Hi Matt,

Check if “Pre-computed Navigation Mesh” is enabled on your Static Meshes - this is likely the cause of that 225MB allocation. You can find this under the “Navigation” section in Static Mesh settings as “Can Ever Affect Navigation”.

If you don’t need any navigation/pathfinding features, you can safely disable it to free up that memory.

Best regards!

select your main landscape in the outliner, in details find “used for navigation”, turn to false.
