Update: I tried with the 4.10.1 binary, and I get the same failure.

After packaging, and then cooking again it works with the binary. I’m going to try it on a real project now.

Using a source UE4 build seems to be the only way to reproduce this error. Using the binary, after packaging, then I am able to build content.

Hey

The cook fails because UE4Game is not built by default with a source build. After compiling UE4Game (which packaging does automatically) the project can be cooked successfully.

Cheers
