Automatic Attribute Assignment (RBX_AutoSetup_AssetConfiguration) breaks plugins

Vinnie24_YT · September 5, 2025, 3:09pm

Importing meshes through the Asset Manager applies an attribute that can break certain plugins.
Imported meshes cannot be modified by plugins that affect attributes, as the attribute “requires CoreScript permission”.

“Katana” Mesh in this model is affected by said attribute Rig.rbxm (30.0 KB)

Expected behavior

I believe the attribute should be disposed of after importing the mesh (instantly).

Hello. I get this error when a server script adds an attribute to a model.


Attempt to assign attribute RBX_ReimportId. CoreScript permission required

It happens with my specific model—it has 3 children (Imported Meshes).
