    Hello, I'm trying to upscale my texture using script:

    Code (CSharp):
    1. public Texture2D tex;
    2. ...
    3. tex.Resize(64, 64);
    But unity throws me error from the title. I've googled a lot about making the texture readable, but I found, that for some reason, my inspector don't have checkbox for making it readable:

    So, how and where I can make texture readable?

    (I'm using Unity 2020.1.9f1)

    Expand the "Advanced" section and turn on "Read/Write enabled"

    My sprite has the Read/Write toggle enabled but I still get this error:

    Using alphaHitTestMinimumThreshold greater than 0 on Image whose sprite texture cannot be read. Texture 'sactx-1-4096x4096-Crunch-HiddenObjectAtlas-740480a6' is not readable, the texture memory can not be accessed from scripts. You can make the texture readable in the Texture Import Settings. Also make sure to disable sprite packing for this sprite.


    Any idea?

    Solved: make sure to enable the Read/Write toggle also on the atlas if you're using any
