Basic Project Will Not Package/Launch

Hi,

I’ve created a game in UE4 that is now failing to Launch. It used to be able to but now even default template projects will not Launch. I recently moved from 4.8.0 to 4.8.1 but I’m not sure that is the issue. I’m on a macbook pro, 10.10.4.

I’m loving UE4 and my game I’ve created and would love some help figuring this out.

Thanks,

Resolved

the Substance plugin does not with 4.8.1.
