Problems to import FBX model

Hey guys, hope you are doing well.
Our 3D team reported a problem when importing a FBX in Roblox Studio, and we couldn’t diagnose the exact problem and how to fix.

This is the full report:

When importing this lion head fbx from blender it loses the reference to the material and the import either fails or succeeds depending on which tool inside Roblox I use.

If I follow the “Plugins → Avatar Importer” procedure, I can import the fbx but the material is compromised (images 1 and 2)

Furthermore, other members of the team experience this: the model not only has the material compromise but it’s also upside down


Otherwise, if I follow the “Avatar → Import 3D” or even “Home-> Import 3D” procedures, the mesh is invisible (both into the preview and once imported) and I get the following console error: exception while signaling: invalid unordered_map<K, T> key

This also happens with other headwears we are developing like this hippo and corintians helmets.

Thanks for the report! We’ll follow up when we have an update for you.


Hey sorry I’m way late, hopefully this issue is resolved on your end, I just tried it with the latest version of studio and it seems to work (we shipped a lot of fixed in the last few months).

Please let me know if you are still having this issue. Again apologies for the delay :frowning:
