Adjusting Basic Parameters in Material Editor

After the auto-conversion, you are able to adjust the rendered image without retouching the contents in the original iClone project by using the parameters provided by the Material Editor.

1. Create a project in iClone.
   
2. Auto convert it to Indigo for rendering.
   
   Determine the material that you want to modify (in this case, the material of the tetrapod block).
3. Go back to iClone and select the object containing that material(s).
4. Open the Indigo Render Setting panel.
5. Under the Material List in the Indigo Material Editor section, you will see several sliders.
   
   • Base Emission: This value defines your object as a light source and determines the amount of light emitting from it.

     Base Emission = 7000	Base Emission = 17000

   • Base Emission - Red, Base Emission - Green and Base Emission - Blue: These three sliders determine the color of the light source.

     Base Emission - Red = 1.00 Base Emission - Green = 0.00 Base Emission - Blue = 0.00	Base Emission - Red = 0.00 Base Emission - Green = 0.25 Base Emission - Blue = 0.50

     Note:

     If the object originally contains a Glow Texture, the texture will be ignored after these emission-related parameters are utilized. Turning on the emission feature slows down the speed for rendering.

   • IOR (index of refraction): This value controls the influence of the glossy coating. It can also be taken as the resistance a photon experiences to pass through a medium; higher values produce a stronger specular reflection because less light can pass through the medium and are instead reflected from the surface.

     Low IOR value. More light can pass through the surfaces and the medium of an object. Suitable for transparent or less reflective objects.	High IOR value. Less light can pass through the surfaces and the medium of an object. Suitable for polished or metallic objects.

   • Exponent: The exponent parameter controls the roughness of the surface, with higher exponents corresponding to a smoother, more polished surface with mirror-like reflections.

     IOR: 5 Exponent: 100	IOR: 5 Exponent: 10000

     Note:

     The IOR feature must be turned up in order to experience more noticeable changes in the Exponent property.

   • Fresnel: The strength of the reflectivity on faces with different angles to the camera without changing the material characteristics of the surface.

     Fresnel: 0.3 Fewer faces in different angles reflect the environment.	Fresnel: 1.00 More faces in different angles reflect the environment.

     Note:

     The IOR, Exponent and Fresnel parameters only work when the material settings of the object are set to Indigo Phong, Glossy Transparent and Phong or Glossy Transparent Based Blend. Otherwise, modifying these three parameters does not cause any material change when rendering in Indigo.

6. After you have done with the adjustments, export the project again for rendering in Indigo.

   Note:

   Please note that the original iClone project will not be influenced by these adjustments.
