I’m having the same problem myself now, curious what the solution would be.

Hi kiranlaks -

I’ve only seen this error before when I launched Swarm Agent from version 4.7 and then built lighting in a 4.8 engine. It went away once I started the 4.8 installation of Swarm Agent. Since the engine was not in the directory swarm expected it defaulted as above in your log. It however did not keep me from building lighting in the project. Are you experiencing an issue with building the lighting?

Thank You

Eric Ketchum

Hey Eric! I know in my case, I have 2 PCs dedicated to Swarm (running Windows 7, fully updated and using the 4.8 swarm agents/coordinator)…coordinator sees my own workstation and the other agents, but when I build (in this case it’s a full level) it never distributes the jobs to Swarm.

The error that stands out to me (didn’t see anything else when changing to super verbose) was “Failed to determine engine directory: Defaulting to …/…/…/Engine/.”

Hi JParkerRH -

We have had an issue with Coordinator’s not working correctly when they initiate the build in the past, but that should be corrected in 4.8. To confirm for me can you please look in the About UNreal Engine tab under Help and give me the full Changelist number, it should begin 4.8.2-#######.

Thank You

Sure thing!

4.8.2-2614606+++depot+UE4-Releases+4.8

Hi JParkerRH -

I was able to reproduce that the Swarm Coordinator is not distributing the lighting builds as expected and have entered a report as UE-18882. As we continue to investigate this issue, I will keep you informed here.

Thank you for your assistance in tracking this down -
