The realistic material

The first and default material type is realistic. It is energetically equilibrated.

The energy preservation model

The shading model uses three basic inputs:

These three inputs are involved in the energy preservation rule: the sum of the diffusion + reflection + transmission terms is always lower than or equal to 1.

Diffusion, reflection and transmission

More parameters influencing the reflection effect are available like glossiness and IOR (index of refraction).

Increasing the glossiness from 0 to 1

Bump channel

The material also contains:

Adding bump texture

Back diffuse and translucency

Two more channels are available for plants only:

These two channels are very useful to render plant leafs.

Masked material

The material can be defined as masked. In this case, the transmission texture is used as a mask. A property allows to set the alpha threshold over which the geometry is masked.
