Hi guigui441987,
in your personal section you can manage the materials that you have shared in LiveDB from Standalone. Basically you can change the name, add a description, or remove the material.
In v4doctane, go to Live Viewer menu Materials/LiveDB, select the LocalDB category, and drag and drop your material on it from the Material Manager.
Then go to Standalone, Outliner/LocalDB panel to load the material saved from c4doctane, and follow the instructions in this document on how to upload materials into LiveDB:

Alternatively, in c4doctane you can right click a material in node graph, save it as .orbx file, open Standalone, import the .orbx material, and save it il LiveDB for sharing.
Note that the thumbnail will be created separately after some time, and the material will be displayed with a X at the beginning.
