Adobe provides many different modes of superimposing layers, including
normal, darken, lighten, difference, multiply, screen, dissolve, hard light, hue,
saturation, color, luminosity, overlay, and soft light.
You can use PSD files as bitmaps, viewport backgrounds, and so on. You can't
render to a PSD file.
3ds Max supports Photoshop 6.0 format, and allows you to use image layers
as bitmaps, as well as the entire composited graphic.
Limitations
Bits Per Channel Photoshop supports images with 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 the following modes:
RGB
Grayscale
3ds Max doesn't support the following Photoshop modes:
Indexed Color
Bitmap
Duotone
CMYK Color
Lab Color
Multichannel
Non-Image Layers Layers other than image layers (for example, text layers)
are not supported. In Photoshop, you can rasterize a non-image layer to
make it an image.
Compositing Options Compositing options between image layers, which
require processing by Photoshop, are not supported.
