    Hi there! Have anyone tried using Adressables and SpriteAtlases?

    If so can you please share your workflow. I tried listening to

    Code (CSharp):
    1. SpriteAtlasManager.atlasRequested
    and load the atlas with

    Code (CSharp):
    1. Addressables.LoadAsset<SpriteAtlas>("atlas")
    but atlases with more then one page are not working correctly.

    Sprites on the first page are shown but sprites on the rest of the pages are not.

    Regards

    I have also encountered this behavior. The Spite data within the Atlas is loaded, but the additional textures do not get built into the bundle.

    Additionally, I have had single-sheet Atlases sometimes fail to have their texture built into the bundle as well. This seems to happen at random (even on back-to-back builds); I have been unable to replicate it consistently. I once had a two-sheet Atlas fail to bundle either sheet texture.

    Finally (when they do load correctly), I am at a loss for how to unload addressable Atlases from memory. Releasing the Atlas asset does not seem to have any impact on the footprint (or references to the atlas/sprites listed in the profiler). Destroying the Sprites that were cloned out of the Atlas has no effect, other than keeping total Object count down.

    When I get white textures from single sheet atlas Build > Clean > All Cache Data did the trick.
    But multiple page sprites still does not work even in 0.4.0

    Thanks for posting this. I've filed the bug of multi-page atlases not working in our system.

    Have there been any updates with this? Is it specific to addressables or is it a general issue with asset bundles and multi-page sprite atlases?
