The Transfer Shading Sets tool allows you to transfer the shading assignment data between two objects that may be topologically different. For example, you can transfer shading assignment data from a cube to a sphere. Faces in similar locations are assigned the same shading data.

Select the space in which the attribute transfer is performed. Choose between World space and Local (model) space.
