After installation, Live Link can be initiated in one of the following 2 ways:

Start Chaos Vantage

Section
Column

 Use the Start Chaos Vantage in SketchUp. It can be accesses either from:

 

Fancy Bullets
typecircle
    • the Start Chaos Vantage button in the Chaos Vantage toolbar which is hidden by default but can be enabled from View > Toolbars > Chaos Vantage
    • the Start Chaos Vantage command accessible from Extensions > V-Ray > V-Ray Live Link

Using either of the two initializes a live link session between SketchUp and Chaos Vantage. It automatically:

Fancy Bullets
typecircle
    • Starts Chaos Vantage if it is not already running;
    • Sends the scene to Chaos Vantage on 20701 port ;
    • When clicked again, closes the Live Link connection.
