Here is the Icons that I made
PSD Layer Splitter
 PSD Layer Sequence
PSD 3D Layer

After some of my tests:
In fact, "depth" does not participate in the actual calculation of the position, so we don't need to change the depth value. It is simply a parameter that allows the user to scale. The formula I mentioned before, depth here is equivalent to the scaling value of width and height, which I think you can understand. That is, instead of assigning a value to depth, we can use it to "restore" the user's scaling value to the current layer.

I noticed that in some cases
a rate above 999 makes the first stream (background layer) leave the field of view, just as an Offset above 99 makes the last stream (foreground layer) leave the field of view.

@editeiro That's because m can't be -1 in the following code:

        public static void SetTrackMotion3D(Vegas vegas, VideoTrack track, int i, double rate = 0, double offset = 0)
        {
            if (track.CompositeMode != CompositeMode.SrcAlpha3D)
            {
                return;
            }

            double unit = vegas.Project.Video.Height / 20, m = (i * rate - offset) / 100;

            foreach (TrackMotionKeyframe kf in track.TrackMotion.MotionKeyframes)
            {
                kf.Depth = unit * (1 + m);
                kf.Width = vegas.Project.Video.Width * (1 + m);
                kf.Height = vegas.Project.Video.Height * (1 + m);
                kf.PositionZ = unit * m * 193 / 9;
            }
        }

It can be mitigated by changing the formula for m slightly, such as:

m = Math.Pow(2.71828, (i * rate - offset) / 100) - 1;

In this way, the larger the offset, m will always approach -1, but large offset values will inevitably cause display problems.

To sum up, a more perfect version of this script would look like this:

@zzzzzz9125 Thanks, i made more teste and work very well!
It's a good option to working fast in 3Dcomps, in the most cases, i use the rate until 100 and pffet in until, i'm not overpass this values, and works great.

Only left some adjustments that will need depending of the result wich I want to reach.
So thanks for more that efforts, You Rock dude!
This will save MUCH time in my next projects

@zzzzzz9125 I quote you right here: https://www.vegascreativesoftware.info/us/forum/creating-a-script-to-make-3d-extrusion-in-a-text--146620/

I have other idea to a 1-Click Script envolving 3D Comps, this time to make a 3D extrude Text ;)
Best

does this script still work? i tried it and i get an error

@ansonmccosh, it ought to still work. I've never tried it.

You might look at this tutorial too:

You might look at this tutorial too:

Thanks il check it out...but any ideas on what that error means?

@ansonmccosh not without testing the script using your VEG file (some media would probably need be required too) in order to test out where/how it is crashing.

@ansonmccosh not without testing the script using your VEG file (some media would probably need be required too) in order to test out where/how it is crashing.

so it works on my v19 after defaulting all settings. so it looks like i have a setting on v22 that is creating a conflict.

does this script still work? i tried it and i get an error

@ansonmccosh I can't reproduce your problem in my VEGAS Pro 22 build 239.

However, I can see the error lines in your screenshot. They should be:

if (track.IsCompositingParent)
{
    track.SetParentCompositeMode(trackCM, false);
}
newTrack.SetCompositeMode(COMPOSITEMODE, false);

Perhaps in some ways you can't use VideoTrack.SetCompositeMode() and VideoTrack.SetParentCompositeMode().

You can try replacing all similar lines in the script with something like the following:

if (track.IsCompositingParent)
{
    track.ParentCompositeMode = trackCM;
}
newTrack.CompositeMode = COMPOSITEMODE;

If you have a problem with a particular project, you can send it to me and discuss where the problem is.

Thanks for the response i did try it out and got the same error but i fixed it by simply restoring vegas 22 to default setting and i could use the original script..all good now...Thanks guys

Still, splitting complex psd files on the vegas timeline does not comes out looking anywhere near how they originally look in photoshop...... Not a fault with the script, its just the way it is.
