Why is there no static mesh object created at runtime in the scene?

Hello Mirro1871, and thank you for posting.

When testing this, does the level get a bit darker? Using your parameters, I noticed that the scale you used is a tad large. Would adjusting the relative transform scale help? This is how I resolved this concern on my end.

If you have any additional details, feel free to share them.

In the meantime, I hope this helps.
