Scripting 3D track motion

I’ve uploaded this picture for a different topic but it shows quite well what this script does (look at the left picture):

Hi,

Sorry if you just answered this here but I guess I’m missing something obvious. I’m trying to simply add some video tracks to a project and change the composite mode to SourceAlpha3D as well.

The following C# code is part of a nested loop to create a video wall and set the size, and it gets the tracks in but then I am simply, afte all tracks are added, trying to change the composite mode for specific tracks.

VideoTrack track = new VideoTrack(trackIndex++,”Track”+trackIndex);
vegas.Project.Tracks.Add(track);
TrackMotionKeyframe mkf = track.TrackMotion.MotionKeyframes[0];
mkf.Width = TrackWidth;
mkf.Height = TrackHeight;

I’ve tried to reference the compositemode property of a “VideoTrack” but keep getting a message indicating it’s a type not a variable. Please help me see what I am obviously missing.

Thank you,

Andre
