    Hello!

    When I try to get pixel data from spritesheet with PVRTC compression on IOS by GetPixels I see the following errors:
    Invalid texture format: 33
    Image invalid format!
    Unsupported texture format - needs to be ARGB32, RGBA32, BGRA32, RGB24, Alpha8, RGBAFloat, RGBAHalf or one of supported compressed formats.
    UnityEngine.Texture2D:GetPixels(Int32, Int32, Int32, Int32)

    Although it works with RGBA Compressed ETC2.
    Texture is 2048x2048, read/write is enabled.
    There`s nothing about it in documentation. How can I deal with it?

    Thanks.

    This is still happening in Unity 5.5.1.f3. When is this going to be fixed? Any word from the team?

    Reading pixels from compressed texture formats is not supported.
