iOS UCB / 5.1.2f1 Fails randomly on shaders

Unity Services
1

Sometimes it works, sometimes it doesn’t. When it fails, UCB restarts the build one time, then it just fails silently on the 2nd build.

Known UCB issue?

Still getting this on 5.1.3f1.

Happens on latest 5.2.0f3.

@David-Berger This is a intermittent issue. Sometimes it works - sometimes it doesn’t. Any ideas?

How long does a successful build typically take to complete in Cloud Build? And how does that compare to a local build?

Thanks,
Patrick

UCB: For iOS about 20 mins (when it works). Locally it takes a few minutes (and always builds).

Ok thanks for the info. Builds that quick usually don’t have this type of issue, so we’ll have to do some technical investigation.

Cheers,

Hey idunlop_oefun
Can you direct message me a link to your project to see if I can’t figure out what might be causing this issue?

Thanks,
Ryan

Just sent you the link on UCB for the project.
