More about Modifying Material Lighting Properties

Click the table to access a detailed description of the lighting parameters and the associated results with given values.

When setting the Reflectivity parameter, you can also set advanced reflection settings if you wish to use a customized environment image for environment reflections. For more information, refer to Defining the Reflection Settings in this guide.

A reflecting material lets you visualize the environment image it reflects. Here is the priority order in which they are seen:

1. Material reflectivity image defined in the Advanced Reflection Settings dialog box (for Real Time Rendering users only).
2. Environment image defined in Tools > Options > Material Editor > Environment Image File.
3. Default environment image provided with Version 5.

Note: All values can be defined either using the scroll bar, the arrows or directly in the box.

• All lighting parameter values range from 0 to 1.
• Any amount of reflectivity, however small, means that you can no longer visualize the mapped texture simultaneously with the reflected scene. If you want to see the texture, make sure you set the Reflectivity parameter to 0 in the Lighting tab.
  Reflectivity between 0 and 0.2
  
  
• If you set the Reflectivity parameter to 1, you can only visualize the reflections on the material as shown in picture 2.
  Reflectivity between 0.2 and 1
  
  
• Provided that your hardware configuration supports it, this is no longer the case if you can take advantage of the CgFX technology which lets you visualize a material with both a texture and reflections if you set the Reflectivity parameter to 0.2 for instance as shown in picture 3.
  Reflectivity = 0.2
