Additive scene loading and Resources.UnloadUnusedAssets

Unity Engine

Hello,
I recently read that when unloading a additive scene, Resources.UnloadUnusedAssets is required to manually to unload unused assets from memory. My question is, if I don’t call it, next time the unloaded scene is loaded again, will it use the remained assets memory?

The profiler is your friend:

Windows -> Analysis -> Profiler

Let us know what you find out.

Also, if something exists only in one scene, DO NOT MAKE A PREFAB out of it. It’s a waste of time and needlessly splits your work between two files, the prefab and the scene, leading to many possible errors and edge cases.

Yes.

I ln this case, installing the Memory Profiler package and going to
Windows -> Analysis -> Memory Profiler is likely the more informative way of looking at this.
