Specifies whether the layer should be taken
into consideration during computation of the result color and alpha
of the layered texture. If off, it is as if the layer does not exist.
Use this when you want to isolate a particular layer to see how
it looks by itself.
Alpha is Luminance
Lets you determine whether
the Alpha should be the luminance
of the Out Color, as with other 2D
textures, such as a File texture.
Automatic Alpha for File and Layered
Texture nodes
Hardware Color
Specifies which color
objects using this texture display in the view while in hardware
shading mode (not hardware texturing mode).
Blend modes
Layers can be blended
with those below them using the Texture Blend attribute
in the Layered Texture’s Attribute
Editor.The Blend Mode specifies
how the selected layer blends with the below it. The following lists
the blend modes:
None
Edits or paints each pixel to make it the
result color. This is the default. (Normal mode is called Threshold when
you’re working with a bit mapped or indexed-colored images).
Over
The top layer is applied like a decal to the following
layer. The shape of the decal is determined by the top alpha.
In
The
background texture is cut in the shape of the foreground alpha.
Out
The result is the opposite
of In. It is as if the shape of
the foreground layer has been cut out of the background alpha.
Add
The result color is the foreground color
added to the background color as if being projected on the background
through a slide projector. The result color is then applied over
the background color using the foreground alpha to define the opacity
of the result.
Subtract
The result color is the
foreground color subtracted from the background color. The result
color is then applied over the background color using the foreground
alpha to define the opacity of the result.
Multiply
Looks at the color information
in each layer and multiplies the bottom color by the blend color. The
result color is always a darker color. Multiplying any color with
black produces black. Multiplying any color with white leaves the
color unchanged.
Difference
Looks at the color information in each
layer and subtracts either the blend color from the bottom color
or the bottom color from the blend color, depending on which has
the greatest brightness value. Blending with white inverts the bottom color
values; blending with black produces no change.
Lighten
Looks
at the color information in each layer and selects the bottom or
blend color, whichever is lighter, as the result color. Pixels darker
than the blend color are replaced, and pixels lighter than the blend
color do not change.
Darken
Looks at the color information
in each layer and selects the bottom or blend color, whichever is darker,
as the result color. Pixels lighter than the blend color are replaced,
and pixels darker that the blend color do not change.
Saturate
Creates a result color
with the luminance and hue of the bottom color and the saturation
of the blend color.
De-saturate
The
result color is the background color with saturation decreased in
proportion to the foreground color scaled by foreground alpha. If the
foreground color is red, for example, the resulting color is the
background color with desaturated reds.
Illuminate
Creates a result color
with the hue and saturation of the bottom color and the luminance
of the blend color. This mode creates an inverse effect from that
of the Color mode.
