The imported model in D5 is a whole. How to separately adjust individual objects?

Currently the model is imported into D5 as a whole and relies on the materials to differentiate.

It is recommended todifferentiate the materials in the modelling software before importing the model into D5. After importing into D5, you can use the shortcut key "i" to quickly pick up the material for editing, or you can lock the model in the left sidebar--object list, and click on the model for material editing.
