Happening for me too. I have tried reinstalling Roblox studio and using different blender files and textures (ones that I haven’t had issues with prior) only to get the same error.
I’ve been having the same issue too. I keep trying to upload meshes, but I get the same thing. I kept renaming my meshes to see if that would work, but I guess not.
You can upload with asset manager. But another thing that’s seems broken for me since today is the sizing… Whatever size I make it keeps telling me the size is too big while they are smaller than the meshes I did yesterday
We are looking into the issue, from my initial testing it seems that this only happens when using the MeshID property importer in unpublished place.
If the place is published, or if you use Import 3D or the Bulk Importer the issue does not seem to occur. Will update when I have more information
Minor update: the issue seems to be inconsistent in published places, I have successfully uploaded on a freshly published place, but hit the error on a previously created one
If you run into this issue after June 16 2024: make sure you have restarted studio at least once since June 13.
On the day of the issue we did 2 things:
A short term fix to resolve the issue ASAP
Started work on a longer term fix
The long term fix was released and enabled with Studio yesterday, but only applies when you restart Studio. Because we know some people keep studio open for extended periods of time, we are waiting until Monday to remove the short-term fix.
Please make sure you have restarted Studio at least once between today and Monday to avoid this issue resurfacing !
