(iOS) Create Thread: DXT1 compressed textures are not supported when publishing

Unity Services

I’ve just updated to Unity 2017.3.1p3 and I’m getting the following error when building to iOS

Errors:
DXT1 compressed textures are not supported when publishing to iPhone
Packages/com.unity.ads@2.0.3/Editor/Resources/Editor/landscape.jpg

A user in this Issue Tracker (https://issuetracker.unity3d.com/is…s-are-not-supported-when-publishing-to-iphone) suggests removing the images from Unity Ads, but I’m using Unity Ads so can I remove these images safely?

I successfully built yesterday with Unity 2017.3.1p2 so I’ll probably roll back and see if the issue persists.

Hi,

Thanks for bringing this up!

Can you try if these steps help:

  • Disable your Ads integration from the services window in the editor
  • Download the Unity Ads Asset Store package
  • Initialise Ads manually using your Game IDs
  • If you still see this error, reimport everything

Please let me know how this works for you.

@mikaisomaa Thanks! Asset Store version of Unity Ads compiled fine :slight_smile: Do the latest patches not always integrate the latest version of Unity Ads?

Glad to hear that!

Different editor versions have different embedded versions of the Ads SDK - mostly not up to date. Currently the best way to stay up to date is by using the Asset Store package, but in the future I expect the package manager + services window to be the ways to go, since then you’ll be able to stay up to date even with the embedded packages.

The first solution doesn’t work. I didn’t even turn on the Unity Ad service, but still got the same error. By the way, I used analytics services but worked well.

I have the same - it is a bad bug, considering I never selected to have ads in the first place.
If I go to the services window it says I am not online/signed in, if I sign in I get nothing helpful as I do not have a project ID - do I really need one?

Why can you not just disable ads - in fact have them off by default?
Or is this a bug coming from project upgrading over time?!

Edit: That was Unity 2017.3.1, it does appear fixed in latest LTS release 2017.4.6f1
