DomuS3D®: tips&tricks

Learn how to use Self-Illumination material, and download a free project for your DomuS3D®

How to use Self-Illumination material

  1. If you want that an item (or a part of it) will emit its own light we can use a specific material available in your Application database. It is the “Autoilluminante” material (Self-Illumination). If you assign this material to an object's layer, it will make its own light thanks to the parameter Additional Color, as you can see in the following image. You can access the material mask double clicking the material in the components window; in there, you can change the power of the light changing the Add. Color Multiplier value. As you can see, thise parameters are available in the Advanced paramteres section of the material.
  2. Let's see how to apply the Self-Illumination material to an object. Search and find "Autoilluminante” material in the “Materials” section of the Components window (you can change its name inside the database in order to call it the way you prefer). Select the preview image with the left mouse button, drag and drop it in the Navigation window. Be careful to drop it exactly over the glass of the light , as you can see in the next image.
  3. If you want to maximize or minimize the light intensity and effect, you can change the Add. Color Multiplier parameter of the material. Such a modification may be necessary in case the room has a strong light (commonly when the sun light enters the room).
  4. In the next images you can compare a rendered image without the Self-Illumination parameter, and another one with such effect applied to the lamp

If you have DomuS3D® Venus or later, you can download this project clicking this link

In this way you can see how the material has been applied to the lamps. The proejct has been created using V-Ray rendering engine.

Coloring the Self-Illumination material

  1. In this second example you can see how to customize the Self-Illumination material color.
    Once you have applied the Self-Illumination material to an object in the Navigation window, select it with the right mouse button and choose Properties.  

    Then open the Materials Tab . Select, with the left mouse button, the layer related to the light (in this project it is called VETRO OPACO), and you will see that the associated material is Self-Illumination.

    Now click the Material button and select Modify. In this way you can access the material properties mask related to the material instance available in the project (so you will not modify the one available in the Application database).
    Open the Advandced Parameters section, go down up to Additional Color section: click    button, choose the color you want, in case increase Add. Color Multiplier value (for example a 1300) in order to have a stronger effect (e.g. if the sun light is entering the room). Click OK to confirm.

  2. Here's an example where the Self-Illumination material for the spot lights in the shower box has been changed to RGB 0; 255; 255

  3. Hare are some more examples where Self-Illumination has been applied to spot lights in the scene
