Individual Layer displays list of layers to choose from.

Full Frame —When on, uses the entire layer as the

bitmap. When off, uses only that portion of the

lay er occupied by image data. Default=on.

Limitations

B its Per Channel—Photoshopsupportsimageswith

1, 8, and 16 bits per channel (1-, 24-, and 48-bit

RGB images, respectively). 3ds Max supports PSD

images with 8 or 16 bits per channel. (In practice,

there are very few images with 1 bit per channel.)

While Photoshop can load images with 16 bits per

channel, layers are always 8 bits per channel.

Modes—3ds Max supports .psd files saved in t he

following modes:

•RGB

•Grayscale

3ds Max doesn’t support the following Photoshop

modes:

•IndexedColor

•Bitmap

•Duotone

•CMYKColor

•LabColor

•Multichannel

Non-Image Lay ers —Layers other than image layers

(for example, text layers) are not suppor ted. In

Photoshop, you c an “rasterize” a non-image layer

to make it an image.

Compositing Options—C ompositing options

between image layers, which require processing by

Photoshop, are not supported.

RLA Files

The RLA format is a popular SGI format that

supp orts the ability to include arbitrary image

channels. While setting up a file for output, if you

select RLA Image File from t he list and click t he

Setup button, you’ll go to the RLA setup dialog.

Once there, you can specif y what channels (and

what format) you want to write out to the file.
