Sprite packer running out of memory

    Anyone else seeing issues with the sprite packer in 4.5.0 running out of memory?

    I have about 200M (compressed) of sprite data representing a few thousand sprites. The Sprite Packer will cause Unity to use more than 3.0GB and often crash. All of my images get packed into about 8 4096x4096 sheets.

    Anyone else seeing this, or know of any work arounds? It happens on Mac and PC. I believe it is going over the 32-bit addressable space limit

    Do you use a custom packing policy?

    Yes, looks like the issue was using AssetDatabase.LoadAllAssetsAtPath (from the old example) instead of AssetDatabase.LoadAllAssetRepresentationsAtPath

    Fixed now, thanks

    How did you fix this? I'm having the same problem. I tried using the new policy example code and it still won't work.

    Still isn't fixed for me either, but I can run it once without restarting. They need to fix the memory usage of the packer or ship a 64 bit editor.

    I imagine there are leaks on the Unity end

    Which version are you running? We've made improvements in 4.5.2p1, see http://forum.unity3d.com/threads/unity-patch-releases.246198/
