Dropped items memory leak

cookereptiles

Hello,
I have some items being dropped in the world by schematic (drop items node), they’re normal pieces of equipment etc which the player picks up as per dropped loot. I’m finding the items are causing a memory leak, the meshes and textures seem to still be referenced after a scene change. I’ve tried destroying the objects before changing scene but they still show up in the memory profiler as leaked. This increases by memory foot print every scene change.

The loot box prefabs are stored in an asset bundle, not sure if this is causing the issue.

Are they being referenced somewhere and how do I change it?

I'll look into it.

Did some tests with the memory profiler and couldn't really replicate this.
While the prefab itself is still loaded due to the asset bundle still being loaded, the spawned instances of the prefab are gone after the scene change, and with it the mesh and textures.

Even if there would be some references to the game object, the game object is destroyed on scene change and the references would be null ...
So, from ORK's perspective there is no issue or nothing I can really do - the rest is up to Unity and garbage collection.

Thanks GIL, it sounds like something on my end. I’m having a similar issue when using conditional prefabs on combatants, it leave parts in the memory.

Hm, probably the same as with the spawned item prefabs - using asset bundles will keep the prefab in memory unless it's unloaded (e.g. the Asset Settings in Game > Game Settings have an option to unload them on scene change), but spawned prefabs are destroyed on scene changes (by Unity, so this has nothing to do with ORK) and their data (like mesh or textures) should be removed by the garbage collector of Unity.
