DwaMixMaterial

Overview

DwaMixMaterial allows for multiple materials to be blended sequentially, and it supports up to 64 material inputs. The bindable mix attribute is responsible for selecting the material, and it ranges from 0 to 63. The range can be specified from 0 to 1, but only if the remap_mix_to_inputs attribute, which scales [0, 1] to [0, num_materials - 1], is true.

Any mix values that fall between material selections will blend the materials together. This blending is the same style of blending performed by the DwaLayerMaterial. In essence, this material provides a combination of the ability to select materials like DwaSwitchMaterial and the ability to blend between them like DwaLayerMaterial.

Attribute Reference

Advanced attributes

blend_color_space

Int enum
  0 = “RGB” (default)
  1 = “HSV”
  2 = “HSL”

Color space used when blending the two material's color parameters

fallback_bssrdf

Int enum
  0 = “normalized diffusion” (default)
  1 = “dipole”
  2 = “random walk”

If child materials disagree on the type of bssrdf, this type will be used instead.

fallback_clearcoat_use_bending

Bool
default: True

If child materials disagree on the type of clearcoat use bending, this type will be used instead.

fallback_outer_specular_model

Int enum
0 = “Beckmann”
1 = “GGX” (default)

If child materials disagree on the type of outer specular model, this type will be used instead.

fallback_prevent_light_culling

Bool
default: False

If child materials disagree on prevent light culling, this will be used instead.

fallback_specular_model

Int enum
0 = “Beckmann”
1 = “GGX” (default)

If child materials disagree on the type of specular model, this type will be used instead.

fallback_thin_geometry

Bool
default: True

If child materials disagree on the type of thin geometry, this type will be used instead.

sss_trace_set

TraceSet
default: None

By default, only the geometry associated with this material contributes to subsurface. The DwaLayerMaterial ignores the sss trace sets of the submaterials. If you want adjacent geometry with different material to contribute as well, specify all those parts here.

Glitter Fallback attributes

fallback_glitter_LOD_quality

Float
default: 0.5

controls quality of glitter at distances where individual flakes cannot be perceived; at lower values, approximation kicks in earlier. This parameter will only be used when layering two distinct glitter materials.

fallback_glitter_debug_mode

Int enum
  0 = “off” (default)
  1 = “blend”
  2 = “color”
  3 = “averageColor”
  4 = “footprintArea”
  5 = “radius”

developer debug visualization modes. This parameter will only be used when layering two distinct glitter materials.

fallback_glitter_layering_mode

Int enum
0 = “physical” (default)
1 = “additive”

layering mode for glitter on top of the under material. physical: conserves energy and glitter attenuates under material, additive: breaks energy conservation but glitter is never darker than the under material (eg. use case: snow). This parameter will only be used when layering two distinct glitter materials.

fallback_glitter_randomness

Float
default: 0.5

randomness of flake orientation. This parameter will only be used when layering two distinct glitter materials.

fallback_glitter_seed

Int
default: 0

The seed for the glitter random number generator. This parameter will only be used when layering two distinct glitter materials.

fallback_glitter_space

Int enum
4 = “object”
5 = “reference” (default)

The space to calculate the worley noise in, defaults to reference space. This parameter will only be used when layering two distinct glitter materials.

fallback_glitter_style_A_frequency

Float
default: 1.0

0 implies none of this style, 1 implies all the flakes will get this style. This parameter will only be used when layering two distinct glitter materials.

fallback_glitter_style_B_frequency

Float bindable
default: 1.0

0 implies none of this style, 1 implies all the flakes will get this style. This parameter will only be used when layering two distinct glitter materials.

fallback_glitter_texture_A

String filename
default:

filename that points to a texture .exr or .tx file (must be mip-mapped and tiled with maketx). This parameter will only be used when layering two distinct glitter materials.

fallback_glitter_texture_B

String
default:

filename that points to a texture .exr or .tx file (must be mip-mapped and tiled with maketx). This parameter will only be used when layering two distinct glitter materials.

General attributes

extra_aovs

Map
default: None

Bind this attribute to a 'ListMap' that contains references to ExtraAovMaps that specify additional outputs that can be assigned to a RenderOutput "light aov" result

invisible_refractive_cryptomatte

Bool
default: False

Indicates whether material should/should not appear in the refractive cryptomatte layers
