To use a sequence of image files to create an animated file texture, the file extensions must be separated from the basename and/or the extension by periods. For examples, see Image Name.
To be evaluated by Maya Creative, animated file textures should be of the form XXX.ext.###, where XXX is the filename, ext is an optional file extension (.sgi, .tif, .iff, and so on), and ### is the frame number.
It is also possible to use file textures of the form XXX.###.ext. We do not support XXX###.ext (without the “.” between XXX and ###), nor XXX.YYY.###.ext (but XXX_YYY.###.ext is fine).
