A friend messaged me that his mesh cars were glitching. A bit later, we received reports from our game Emergency Emden that the same issue was happening there as well!
These meshes can’t be fixed on their own, and it appears to be an engine-related issue.
Here some screenshot from Emden and other friends:
Yup, also experiencing this. Everything was fine in studio when a freshly joined player reported the issue. Once I reloaded my studio, that too was affected.
i can also confirm and also add one detail, the glitch seems to affect instances randomly. the two models i put side by side use the same meshes but one was pulled from serverstorage while the other was in workspace, even though this didnt happen with other instances pulled from serverstorage that had glitched versions in workspace
