Welcome to Part V of Buckingham Palace Gates tutorial. From Part I till IV, we have covered three lighting types in Artlantis Studio. From this tutorial onward, we will explore the animation capabilities in Artlantis Studio.

We will animate the gate to rotate 90 degree on both sides. click the below photo to view the end result video. Once finished, click Back to return to this tutorial.

Creating Internal Artlantis Object

In Artlantis Studio, You can create object out from the portion of the model. There are two types of Artlantis Objects: Internal Object (resided inside an atl file) or External Object (A separate file with file extension aof). If you need to use the object frequently on various atl files, it is better to save it as External Object - a standalone file. You can then make the external object visible in Catalog Window, and just drag and drop to use when needed.


In this project, we are going to make the gate to become internal object. You can't animate it if they are not object. We will not use them in other atl file, so, no point to make them as External Object aof file. We will just make them as Internal Object.


1. Let's switch to Object Inspector.

2. In the List Window, click the Activate the Polygon Selection button.

3. In the same window, click the Polygon Selection Mode dropdown, choose Triangle. Model's surface is a formation of many triangular polygon. This Triangle option allow you to select the smallest element of the surface.

4. Click the the left gate to select the first triangular polygon.

Note: The selected triangular polygon is highlighted in white when selected.

5. Click the other side of the left gate to select the second triangular polygon. The left gate is a small area and is formed by 2 polygons only.

6. Click Create an Object from the Current Selection button.

Note: This pop up a dialog box as shown below.

7. In the Dialog Box, enter leftgate at the Name textbox, choose Object as the Destination Layer. Click OK button. Leave it as Internal Object.

Note: An item called leftgate_1 is added in the Objects Layer.

8. Repeat the steps 2-7, to create rightgate internal object.

Done! Let check how the object will response if we rotate it by 90 degree.


9. While the rightgate is still selected in the List Window, in the Object Inspector, set 90 to the Z Rotation value.

Note: The rightgate is rotated 90 degree as per setting. But, the pivot point is at the middle of the rightgate i.e. Point A. We need the pivot point to be located at point B. How to change pivot point of an object? see next.

Changing Pivot Point of Artlantis Object

1. Before we do, let's restore the Z Rotation value to 0.

2. Open up 2D Window. Change to Top View. Ensure you are still at Object Inspector and rightgate is selected.


Note: The blue dot represent the pivot point of the object. You can drag the blue dot to move the object.


The problem is how we know the end side of the rightgate. Here is my stupid method. Don't launch. I will try to move the object to see where is the end, and then undo it  (ctrl+Z for window or Command+Z for Mac). From the movement, i see the end point of the gate.

3. End point is determined. Hold D key and drag the blue dot to the end point.

4. Repeat the step 2-3, change the pivot point of the leftgate also.

Before we proceed to next, we do a check whether both pivot points have been set correctly.


5. Set the Z Rotation value of both leftgate and rightgate to  90 and -90 respectively. View the result in Preview Window.


Note: Both gates open widely. Confirm the pivot points are correct.

6. Set both Z Rotation values to 0 again.

Exporting View from Perspective to Animation

It is time to animate both leftgate and rightgate.


So far, all our work are done in Perspective View, the camera position/angle, heliodon, neon light shaders, lights, background etc are associated to that view. It will save us a lot of time to copy and transfer the view (together with those associated) to Animation Inspector.


1. Switch to Perspective Inspector.

2. In the List Window, right-click the view to display context menu, and then choose Add to Sequence List. This means the the view will be duplicated and sent to Animation Inspector. A Sequence in Animation Inspector means 10s duration of animation.


3. Click the small arrow at the Perspective View Icon to display dropdown, then choose Animation. This switch us to Animation Inspector.

Note: In the List Window, notice that the view you copied in step 2.

Let's delete the original one and just remain the view you copied earlier.


4. Right-click the view called Sequence and choose Delete. Alternatively, you can choose Delete View button.


Note: By default, Artlantis will prepare a default view called Sequence. That Sequence view occupies first 10s time slot, whereas the copied view occupies 10s to 20s ttime slot.

Working on Timeline

Timeline is used to set how long your video is, when various animations shall start and end.


Although we have deleted the Sequence view, the copied view (called Sketchup) is still stayed at 10s-20s slot at Timeline. We need to move the duration to 0s to 10s slot.


1. If the Timeline is not shown, choose Window > Timeline.


Note: Sketchup view still occupies 10s-20s time slot.


2. Drag the blue bar to 0-10s time slot.

The purple ball cursor is used to adjust the current time, you can also jump to specific time by typing in the Current Time textbox. There is 25 fps Frame per Second. For a 10s video/animation, it means 25 x 10 = 250 frames. Artlantis Studio will need to render 250 photos to constitute a video. Wow! Will take ages for a slow machine.


We will reduce the total duration from 10s to 5s. This will reduce the total no of rendering by half.


3. Drag the End Pin to 5s.

4. Click the Recording Button.


As this time, the gates shall be opened widely.


6. Switch to Object Inspector, choose the leftgate_1 in the List Window. Set the Rotation angle to 90.


7. Then choose rightgate_1 in the List Windo. Set the Rotation angle to -90.

Note: Keyframes are added to the timeline. If you wish to remove animation, you can remove the keyframe at the timeline.

9. To see the animation without rendering at Preview Window, click the Play button on the Timeline.

You can now render the video. Sit back and enjoy your coffee for about 1-2 hours depending on your machine spec.


That's all for the tutorial. Hope you can enjoy. Click Like to support.
