I try to export a PB object and get this error:
Couldn't add object to asset file because the Mesh 'pb_Mesh-76840' is already an asset at 'Assets/ProCore/ProBuilder/ProBuilderMeshCache/df001dda7d9849babf8684181f42d7d3.asset'!
UnityException: Creating asset at path failed.
ProBuilder2.Actions.ExportAsset.DoExport (System.String path, .pb_Object pb)
Maybe I did something wrong. I made the PB object, created a empty prefab, drag the PB object onto the empty prefab. then try to export it.
BTW, how do I "undo" create a prefab of a object.
