Meaning
|
CASTS_A_SHADOW
|
If present, the geometry to which this SURFACE_NODE is attached will cast a shadow when rendering with shadows is enabled.
|
|
ambient_diffusion
|
A value between 0 and 100 which is multiplied by the ambient lighting term. A value of 0 means that the drawing's ambient light does not contribute, whereas a value of 100 means it contributes fully.
|
diffusion
|
A value between 0 and 100 which is multiplied by the diffuse lighting term. The diffuse light term is made up of all the contributions from enabled lights in the drawing. A value of 0 means that the drawing's diffuse light does not contribute and a value of 100 means it contributes fully.
|
spectral_intensity
|
A value between 0 and 100 which is multiplied by the spectral lighting term. The spectral lighting is a combination of the spectral color, spectral power, and the angle of a rendered pixel to the angle of view. A value of 0 means that the drawing's spectral light does not contribute, whereas a value of 100 means it contributes fully.
|
spectral_power
|
This value controls the strength of the beam of spectral light. A low value creates a beam with a wide field and low intensity. A high value creates a more intense beam. This value is typically kept in the range 0-128.
|
opacity
|
A value between 0.0 and 1.0 which controls how transparent (at 0.0) or opaque (at 1.0) a surface is. Not all rendering options support this property.
|
spectral_color
|
This color value controls the color of the spectral light contribution.
|
reflection
|
A value between 0.0 and 1.0 which controls how reflective a surface is. A value of 0.0 means the surface does not reflect at all, whereas a value of 1.0 means the surface reflects fully (a mirror). Not all rendering options support this property.
|
freflection_blur
|
A value between 0.0 and 1.0 which controls the crispness of a reflection. A value of 0.0 produces a crisp reflection, where a value of 1 produces a blurry reflection.
|
first_rman_shader
|
This is a pointer to a list of shader definitions used by Renderman-compliant shaders.
