Shotgun in custom unreal build


I’m a bit lost on the set up for getting unreal to launch from a custom engine build.
I have unreal running in the basic build 4.25.3 but we are using a custom build and I cant seem to get shotgun to launch in this build. The integration seems setup to be able to bootstrap the shotgun engine via an file in the /Game/Content/Python directory I copied the code from the unreal shotgun plugin and made a file in this location but seems to be having an issue importing the

LogPython: Error: from tank_vendor import yaml
LogPython: Error: ImportError: No module named tank_vendor

I’m just wondering if there is something that I’m missing in the setup of this or if there is any documentation that I can be pointed to that might help me get unreal going with this custom build.

Thank you,


Hey David,

It sounds like the custom build is missing some components (like tank_vendor). Where to locate and then import that into your custom build is, though, I’m not 100% sure. I’ll check with the Toolkit team and we’ll report back.


Hi David,

It sounds like you may need to clear your bundle cache to remove potentially corrupted .pyc files.

Where is your cache you say? :



I did end up getting this working it hasd to do with the location of the Build and the Shotgun plugin being complied in the engine
