Pychrono irrlicht visualization doesn't appear

[Lily Brenner]

Hi! I'm using the demos for irrlicht under the pychrono module, but the window with the actual visualization never appears. The output from running demo_IRR_assets.py is below. I'm running this on an Apple M2 device, which very well could be the source of the problem.

Hello!

I don't have M2 chip mac, mine has the intel chip; I can provide some insights that could be helpful.

Did you build pychrono from the source, or you installed pychrono from conda? From your output, all textures got loaded fine, and if there were something majorly wrong, it wouldn't get that far. On my mac, the visualization window doesn't pop up automatically, instead, it's in the background, and you can find that in Mission Control view. Could you give that a shot?

Thank you,

Luning
