Hi Rehven,

Sorry for the delayed response to your post. Is this something that is still giving you trouble? I tried creating a local binary build using the command line that you said you were using, and it ended up completing successfully for me.

If you are still having trouble with this, could you provide some additional information about exactly which version of the Engine you are using, which GitHub branch you built it from, and the steps that you followed when building the Engine from source?

Hi Rehven,

We have not heard back from you for a while. Do you still need help with this issue? I will be marking this post as resolved for internal tracking purposes, but please feel free to add a comment and re-open this post if you need any additional assistance.
