    I use Unity Version 2021.3.1f1.32
    When I set secondary sprite for normal map and press Atlas Pack preview, it shows Warning Log
    "There is a mismatch in secondary textures of sprites wasting texture space and potentially break draw call batching."

    After that, I play the game, and the sprites with secondary normal maps are broken(got black lines).

    How can I fix it, thanks!

    This indicates that some textures packed into the Atlas do not have Secondary Textures set. If this is not the case, could you please submit a bug report with a repro project ? Will take a look asap.
    Does the issue occur only when using SpriteAtlas ? We are backporting a fix for a related issue (https://issuetracker.unity3d.com/is...ary-texture-normal-maps-in-linear-color-space) Will post an update once the backport for 2021 is available. Thanks.

    Sorry, It turns out that sprite imports into Unity and set Texture Type to normal map, the Non-Power of 2 marks as ToNearest I need to set to None so the texture size won't go wrong and cause some issue. Didn't know that before
