The Display category contains three different components that are able to explode material objects into their different properties. Each of them is the mirror component from a specific other component used to build materials.
Explode Grasshopper material
This component explodes a native Grasshopper material:
Explode ShapeDiver and glTF 2.0 material
These components work the same way with respect to their respective materials. For the texture properties, the component returns either the URL used or the bitmap object if it is stored with the material.
All three components will give warnings if the material that you are trying to explode is of a different type. The operation will always work at least partially, but some properties might be lost in the process, if they only exist in the original material but not in the one corresponding to the explode component.
