After updating PlayCanvas to version
v1.68.1, I encountered a perplexing issue. The glb models that were originally displayed correctly now exhibit anomalies, causing them to appear damaged and incomplete (as shown in the image). When I rolled back to version
v1.67.3, the issue disappeared. Hence, I suspect it might be a side effect of the version update.
The glb model was downloaded from Sketchfab (link here). I have tried to reproduce the issues I encountered as much as possible within a single repository. You can refer to my repo on GitHub, where simply running the Live server will reproduce the problem.
Another observation is that when I place the same glb model into the scene through the PlayCanvas Editor, the displayed model does not encounter the aforementioned issue. If possible, could you also explain why there is this difference?
I am curious if the situation I am facing is a known issue or if anyone can suggest how I should adjust it for better results.
