This trail renderer example was working, and now seems to be broken in the latest version of the engine.
Issue: After a few seconds, the end of the trail seems to be stuck to the center of the object.
Here’s a third party mod on the trail renderer. From the video, you can see that it used to work, but it’s not working in the latest version of the engine.
Issue: After a few seconds, the trail disappears.
I’m not sure if the two issues are related ( dynamic mesh modification )
