How do you use headless contexts in a loop?

[mehulshinde]

I am using the headless context to build images of glb files. My code looks very similar to the headless example. However, when I run the method in a loop to generate images of multiple glb files, I run into the following error:

Creating EventLoop multiple times is not supported.
stack backtrace:

I am not sure how threading works in this set up so excuse me if there is an obvious thing I am missing here.

Looks like you're creating multiple headless contexts? You should only create one and use that in each loop. Also, you cannot use OpenGL rendering in threads, it's not supported.
