PC players unable to view custom textures/materials

Summary

I published an update to my map this morning (7/28/26). Immediately after, I started receiving reports from many players telling me that the map had no textures. I only received reports from PC players, console players were able to update just fine.

This was a small update that only included a new animation, shown here: zoramaps on X: "cya! https://t.co/YPJ5lzAHGH" / X

Additional Notes

-I will revert to the prior version and see if it resolves the issue
-The update prior to this was 24 hours earlier, 7/27/2026
-On my local PC that I use with UEFN, everything works fine

After getting more info, it looks like this is an issue with performance mode. I was able to reproduce the issue locally
