iClone Settings Turning into Indigo Phong

The iClone material settings that map to the Indigo Phong type are Reflection Texture, Reflection value, iClone Specular, and Glossiness.

If you do not use any of these material settings in iClone, then the material will be converted to the Indigo Diffuse Material Type.

iClone Specular and Glossiness

The Specular and Glossiness values in iClone determine the range of the highlight spot. When they are adjusted, the object rendered in Indigo will be automatically mapped with the Phong material.
The main parameters for the Phong material to be changed accordingly are IOR and Exponent.

The Specular and Glossiness in iClone

Specular: 1 ~ 500 ~ 999
Glossiness: 1 ~ 50 ~ 100

The rendered result in Indigo.

IOR: 1 ~ 6 ~ 11
Exponent: 5 ~ 250 ~ 500

Note:


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

Low IOR value. More light can pass through the surface and the medium of an object.

Suitable for transparent or less reflective objects.

High IOR value. Less light can pass through the surface 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

Reflection Texture and Reflection

The Reflection Texture and Reflection in iClone also determine the reflectivity of a surface. When they are adjusted, the object rendered in Indigo will be automatically mapped to Phong material, too.

The Reflection Texture and its strength in iClone

Strength: 1 ~ 100

The rendered result in Indigo.

IOR: 1 ~ 4
Exponent: 100

The Reflection value in iClone

Reflection: 1 ~ 100

The rendered result in Indigo.

IOR: 1 ~ 4
Exponent: 100

Note:

  • If both Reflection Texture and Reflection are utilized at the same time, then the one with higher strength will be used for setting the IOR and Exponent of the Indigo Phong material.
  • The priority regulation: (Reflection Texture Strength or Reflection) > (the combination of Speculation and Glossiness)
