That can be done but you'd need to define exactly what tracks need to be added.

Thanks i will look this up

hi @ansonmccosh I managed to make a simple version by following some jetdv videos and also using a script that does something "similar" created by zzzzzz9125 I'm not sure if it will work very well for your purpose but here is my contribution to this thread. Also a question @jetdv and @zzzzzz9125 do you approve of this script? is it well done or is there something to improve?

using System;
using ScriptPortal.Vegas;

public class EntryPoint
{
    public void FromVegas(Vegas vegas)
    {
        Project project = vegas.Project;
        
        // Cria e adiciona a faixa "3D Parent" sem definir o Composite Mode imediatamente
        VideoTrack parentTrack = new VideoTrack(project, project.Tracks.Count, null);
        project.Tracks.Add(parentTrack);
        parentTrack.Name = "3D Parent";
        parentTrack.CompositeNestingLevel = 0;
        
        // Cria e adiciona a faixa "Front Plane" como filha da "3D Parent"
        VideoTrack frontTrack = new VideoTrack(project, project.Tracks.Count, null);
        project.Tracks.Add(frontTrack);
        frontTrack.Name = "Front Plane";
        frontTrack.SetCompositeMode(CompositeMode.SrcAlpha3D, false);
        frontTrack.CompositeNestingLevel = parentTrack.CompositeNestingLevel + 1;
        
        // Cria e adiciona a faixa "Back Plane" como filha da "3D Parent"
        VideoTrack backTrack = new VideoTrack(project, project.Tracks.Count, null);
        project.Tracks.Add(backTrack);
        backTrack.Name = "Back Plane";
        backTrack.SetCompositeMode(CompositeMode.SrcAlpha3D, false);
        backTrack.CompositeNestingLevel = parentTrack.CompositeNestingLevel + 1;
        
        // Por último, aplica o Composite Mode na faixa "3D Parent"
        parentTrack.SetCompositeMode(CompositeMode.SrcAlpha3D, false);
        // Se a track for reconhecida como pai na composição, define também o Parent Composite Mode
        if (parentTrack.IsCompositingParent)
        {
            parentTrack.SetParentCompositeMode(CompositeMode.SrcAlpha3D, false);
        }
    }
}

i appreciate this..This is actually very good and it will help. i was actually looking at trying to implement @zzzzzz9125  the depth value and z value and testing if it will work. so far i get errors but i feel like i'm learning more as i go

meant to say "Rate and offset"

@ansonmccosh Something like this? I made a few changes to the original one. It now works for all selected tracks.
