BaseMaterial.
__init__
(self, type)¶ Initialize a new
BaseMaterial
in memory.- Parameters
type (int) – The material type : Material Types.
-
BaseMaterial.
Compare
(self, snd)¶ Check if the materials are identical.
Note
Only the name of the compared materials can be different.
- Parameters
snd (c4d.BaseMaterial) – The material to compare with.
- Return type
bool
- Returns
True if the materials contents are the same, otherwise False.
-
BaseMaterial.
GetPreview
(self, flags=0)¶ Retrieves the preview picture of the material.
- Parameters
flags (int) – Currently not used.
- Return type
Optional[c4d.bitmaps.BaseBitmap]
- Returns
The preview picture or None if it has not been calculated.
-
BaseMaterial.
GetAverageColor
(self, channel=NOTOK)¶ Returns an average color for the material, based on the material preview.
- Parameters
channel (int) –
An optional specific channel to get the average for.
CHANNEL_COLOR
The color channel of a material.
CHANNEL_LUMINANCE
The luminance channel of a material.
CHANNEL_TRANSPARENCY
The transparency channel of a material.
CHANNEL_REFLECTION
The reflection channel of a material.
CHANNEL_ENVIRONMENT
The environment channel of a material.
CHANNEL_FOG
The fog channel of a material.
CHANNEL_BUMP
The bump channel of a material.
CHANNEL_ALPHA
The alpha channel of a material.
CHANNEL_SPECULAR
The specular channel of a material.
CHANNEL_SPECULARCOLOR
The specular color channel of a material.
CHANNEL_GLOW
The glow channel of a material.
CHANNEL_DISPLACEMENT
The displacement channel of a material.
CHANNEL_DIFFUSION
The diffusion channel of a material.
CHANNEL_NORMAL
The normal channel of a material.
CHANNEL_ANY
An unlabeled plugin channel.
- Return type
- Returns
Average color.
-
BaseMaterial.
Update
(self, preview, rttm)¶ Recalculates the material’s thumbnail and updates internal values.
Note
Recalculating the thumbnail/RTTM image is time intensive.It only needs to be done if you want to let the user view the change.The calculations are done asynchronously.- Parameters
preview (bool) – If this value is True then the preview thumbnail is updated.
rttm (bool) – If this value is True then the real time texture map of the material will be recalculated.

GetRenderInfo
(self)¶ Retrieves information about what the material requires from the raytracer and what it will return.
- Return type
int
- Returns
The return values are:
VOLUMEINFO_NONE
None.
VOLUMEINFO_REFLECTION
Calculates reflections.
VOLUMEINFO_TRANSPARENCY
Calculates transparency.
VOLUMEINFO_ALPHA
Calculates alpha.
VOLUMEINFO_CHANGENORMAL

VOLUMEINFO_DISPLACEMENT
Calculates displacement mapping.
VOLUMEINFO_ENVREQUIRED
Needs environment reflection data.
VOLUMEINFO_DUDVREQUIRED
Needs du/dv bump mapping data.
VOLUMEINFO_MIPSAT
Requires MIP/SAT data.
VOLUMEINFO_VOLUMETRIC
Is volumetric.
VOLUMEINFO_TRANSFORM
Needs back-transformed data.
VOLUMEINFO_EVALUATEPROJECTION
Requires texture tag projections.
VOLUMEINFO_PRIVATE_GLOW
