Welcome to the Buckingham Palace Gates Tutorial Part III for Artlantis Studio.

Exploring Neon Light Shader

We have covered the Heliodon Light in Part II of the tutorial. We are going to explore the next light type called Neon Light Shader. Neon Light Shader is one of the shaders inside the Catalog Window. Not like Heliodon, Neon Light attenuates (become weaker) along its path. It acts like our florescent light.



Note: Catalog Window.



Let's turn off the sun lens flare and change the time of the day to 16:15 afternoon.

1. In the Heliodon Inspector, click the Advanced Parameter Setting button, and uncheck the sun lens flare checkbox. Then click Close button.





2. Drag the time slider until time is 16:15.




The Preview Window shall be shown like below.




3. From the Catalog Window, browse to Objects > Basic Geometry > Sphere. Drag the Sphere to the Preview Window and put it on the ground.

 Note: You have inserted an Artlantis Object into the scene.

 

4. Then, browse to Shaders > a Surface > Neon Light Shader. Drag the Neon Light Shader to the Sphere object.




Note: The Sphere becomes light bulb.



As mentioned earlier, one Perspective View is associated to one Heliodon only. But, you can associate many Neon Light Shaders to one Perspective View. Let's see where to set the association.

 

5. Switch to Perspective View. Under the lighting section, you can choose which neon light shaders (many) to apply to this perspective view.



You can control the neon and lighting colors.

 6. Switch to Shaders Inspector.



7. In the List Window, notice that the Neon Light Shader is applied to Sphere_1 object. There are 2 colors: Lighting Color and Neon Color, you can control.



8. Click the Color Picker box for the Lighting Color. From the Color Wheel, choose a yellowish color as shown.



Note: Pick a yellowish color from Color Wheel.



Note: The lighting color of neon light shader is changed.

 



 9. Drag the Power slider to around 23.



Note: The power of Neon Light become stronger, but it attenuates along its path.

Exploring Artlantis Object

In the earlier step 3, we have added a Sphere-artlantis object. Let's understand how to change the dimension of the sphere so that we can put the sphere (the bulb) into the black metal lanterns.

1. Switch to Object Inspector.



Note: In the List Window, object that added to the scene, will be placed at Objects layer.




Let's change the name of the object first.

2. Double-click the Sphere_1 wording, change it to bulb.



Now, change the shape of the sphere to round tube.

3. In the Object Inspector, under the Dimensions setting, uncheck Keep proportions checkbox. Set 0.1, 0.1, 0.5 to x, y, z respectively



Now, change the position of the bulb to place it inside one of the black metal lanterns. You need to make use the 2D View Window to accomplish this.

4. In the Preview Window, click Show 2D View.

Or click Windows > 2D View menu.

Note: 2D View Windows opens. Remember, blue dot represents the object that being selected in the List View. Red dot represents the camera position, blue lines represent the camera angles.




5. Basically, you just need to use the top and front view in the 2D View Window to position the object.

Note: Top View in 2D View Window.





Note: Front View in 2D View Window.




Note: But, the object of the black metal lantern is not transparent and cannot be see through. The light cannot pass through the black metal lantern object.

You need to do the same trick that you did in Part II of this tutorial for the fencing.




6. Back to Shaders Inspector. In the Preview Window, select the lamp post.



Check the Use Alpha Channel checkbox of the png.

 

Set Diffuse Color to white, Transparent to max of the object.

 

 

Note: Problem Solved!



7. Repeat the step 6 to set the transparency of another 2 areas.





Note: Can see the bulb now.



Now, it is time to duplicate the bulb to all the black matal lanterns.

8. Back to Objects Inspector. Select the bulb in the List Window.

9. Open 2D View Window. Hold your Option key (for Mac) or ALT key (for Win), drag the bulb to duplicate another set. Position the new set to the new lantern. Repeat this step for all the 5 lanterns.





10. In the List Window, rename them respectively.



Now, let's duplicate the 5 bulbs to another pillar.

11. In the List Window, use the SHIFT key to select all the 5 bulbs.



12. Hold the Option key (for Mac) or ALT key  (for Window) and drag them to the new pillar position.


13. Render the model.

 

The Neon Light shaders worked!
