Any update on this? The MeshPartHeadsAndAccessories property of workspace still does not work, only randomly will it output an accessory using MeshPart instead of a Part with SpecialMesh.
Is there actually no update on this? My system is suffering from this when it is very clearly solvable (see: BTRoblox) and HumanoidDescription has its own issues of reliability. (i encountered an issue where the face accessory i specified simply never inserted.)
