Reassign Mesh Material ID
Each mesh can be assigned to a different material ID with Reassign Mesh Material ID. Click Edit… to open the dialog.

In the Mesh column, the currently loaded meshes are listed and the corresponding Material IDs are shown on the right. Each of the Material IDs can be reassigned. For the example below, the Material ID of the smaller sphere is originally 02, we change it to Material 03 and click OK. The Material ID for the smaller particle now becomes 03.
Reassign Mesh Material ID is often used after Split Meshes into Connected Components, where meshes are splitted for different components but a same material ID is used. |
