The Live DB is OctaneRender's asset database that stores MaterialsA set of attributes or parameters that describe surface characteristics., Node groups, and even whole scenes shared by the OctaneRender® community and team. The asset database makes it easier to move assets across various OctaneRender® plugins.
To import Live DB materials directly into Modo:
octane.importLiveDb
NOTE: If the material contains texture maps, these will be extracted to the LiveDb Texturemap Folder specified in the Octane Preferences window.
