.IFF File

The iff file extension is related to Maya, a 3D computer graphics software originally developed by Alias|Wavefront and later acquired by Autodesk.

The iff file is the default image interchange format used by the program. These images can have 8 or 16 bit per channel RGB, and optionally Alpha, and can optionally contain a 32-bit floating point depth map (sometimes called a Z-buffer).

Files with iff file extension might be found as images in Autodesk Maya Image Interchange format. Special bitmap image file type.

How to open:

You can work with this image format in Autodesk Maya or view it using XnView.

How to convert:

It seems this file type can be exported to some of the other 3D graphics formats.
