Use the rst 5 options to select the type of layers/layersets or alpha channels should be displayed in
the eld below. All layers/layersets and alpha channels that were saved in Photoshop/BodyPaint 3D
will be shown in the display eld and can be displayed by double clicking on the image (use the SHIFT
key to make multiple selections). At the top left of the dialog window a composite of all selected layers
is displayed - including all mix modes.
What’s meant by “...the rst 5 options...”?
 Layers/Layersets: The various layers or layersets that make up an image.
 Layer Alpha: The selected layers will be converted to an alpha channel: Layer
content will be white, transparent areas will be marked in black.
 Layer Masks: An alpha channel belonging to a given layer.
 Alpha Channels: An alpha channel that affects the entire image.
 Generate Alpha: This option is only relevant if using a bitmap in a layer shader.
The shader will be viewed internally as an alpha channel. This lets you layer the
shader over other layers. Set the bitmap’s MIP interpolation to “0”, otherwise
color seams may result.
Caution:
The selected alpha channels will be displayed as grayscale images and have
no effect on the RGB value of the texture (don’t mask anything out). Only the
following can be extracted: color, masks or alpha channels.
Show Layer Content
Use this option to dene whether or not the layers or alpha channels visible in the display eld should
be included in the preview.
