Thank you for your post. How did you install Scenic? Is it through pip or did you do a repository install? Are you working inside a python venv or any conda/mamba environments? Thank you.

Thank you for your post. How did you install Scenic? Is it through pip or did you do a repository install? Are you working inside a python venv or any conda/mamba environments? Thank you.

I used the repository and installed it by using python -m pip install -e . and I have created a new conda environment for this installation. I've edited the post to include this detail.

BTW, scenic --2d examples/gta/badlyParkedCar2.scenic works well. So, I guess it is to do with the 3d engine?

Thanks. What is the pyglet version currently installed in your environment? Have you tried using venv instead of conda?
