"Assertion Failed" while packaging after 4.16 upgrade

anonymous_user_089a4978 · May 26, 2017, 9:04pm

After upgrading my project from 4.15.2 to 4.16, I started to receive this error while packaging for Android or Windows. I removed Intermediate and Binaries folders, but didn’t resolve the problem.

Try to update CodeWorks for Android, if it is not already updated.
4.16 need 1R6u1 (\Engine\Extras\AndroidWorks\Win64)

anonymous_user_089a4978 · May 28, 2017, 1:00pm

Thanks but this didn’t resolve the problem, still same error.

I tried with Windows too, but still same.

This error is occuring while cooking. Building is always successful.

anonymous_user_089a4978 · May 28, 2017, 6:12pm

Removing ‘Config’ folder solved the problem. Now I am trying to address which config setting is responsible for this bug.

anonymous_user_089a4978 · May 28, 2017, 8:25pm

I found it.

Project Settings > Engine > Cooker > Compile Blueprints in Development Mode

When this option is disabled, the project won’t compile.

anonymous_user_41845f4a · June 1, 2017, 9:18pm

Hello SalihBalkan,

I attempted to reproduce this in the Third Person Template project by disabling that setting and trying to package but it successfully packaged for me. This could be related to the particular blueprints that are being mentioned in the error log. To be sure, could you try reproducing this in a fresh project? If it does end up being content specific, is there anything special about these blueprints that you can think of that differentiates them from the rest of the blueprints in your project?

Edit: Also please provide the full log file that includes one of these failed packaging attempts.

anonymous_user_089a4978 · June 2, 2017, 1:59pm

Unfortunately any logs do not provide information about the error location. Cooking logs, ubt logs and others. There is nothing specific in Blueprints except a few blueprints that have 3-blueprints-long parenting.

I will not be able to do more tests on this issue for now, because we decided that trouble we will have is more expensive than the end-user value of UE 4.16 upgrade. Thanks for your understanding.
