Terrain memory allocation

[GameDesignDude]

I am trying to lower memory allocation. 

Can I delete "remove scene" to lower the memory or just delete the entire section to do so?

  

I would like to delete the sections outside of the playable area.

The memory is per scene.
How large are your terrains? 
You could create imposters, and then delete the terrains.

Hi Bryan,

2048x2048 and the sections are 128x128

We considered making those imposters but did not know we could create the imposter and then delete the terrain!

We will try this and let you know!

Thanks!

No problem! 

You could also turn them into meshes and then delete the terrains as well. 
You can do this by the terrain mesh exporter. 

Gaia Manager - Advanced - Tools - Terrain Mesh Exporter. 
This is what I would do as well. 
Just remember that this is per scene (not the entire project. 
reducing terrain textures will help etc.
