File textures allow you to use any image file as a texture map. The image file can be any of the image file types supported by Maya.

File Texture can also use a numbered sequence of images, allowing you to use an animation as a texture map. To do this:

Some tips for using File Textures:

Aside from the attribute described here, File Texture inherits many other attributes from its parent, Texture 2d.

In the table below, important attributes have their names listed in bold in the description column.

Long name (short name)TypeDefaultFlags
fileTextureName (ftn) stringNULLoutputinputconnectablestorable
File Texture Name is the name of an image file. The image in this file will be used as the texture.

If you want to use a numbered sequence of image files in your texture (i.e., animate your texture, set this to the name of the first image in the sequence.

disableFileLoad (dfl) boolfalseoutputinputconnectablestorable
If set, then the texture file will not be loaded into the node. Instead a flat, grey color will be output in place of the image.
useFrameExtension (ufe) boolfalseoutputinputconnectablestorable
When Use Frame Extension is on, the frame number in the file name will be replaced with the number specified in the Frame Extension attribute. Use this when you want to animate the texture. (See notes in the description section above.)
frameExtension (fe) integer1outputinputconnectablestorablekeyable
Frame Extension replaces the frame extension number in the file name (if there is one). This attribute is only meaningful if Use FrameExtension is turned on.

Keyframe this attribute when you want to use a sequence of files as a file texture. (See notes in the description section above.)

frameOffset (io) integer0outputinputconnectablestorablekeyable
Specifies an offset of the keyed Frame Extension value. This attribute is only meaningful if Use FrameExtension is turned on.
useHardwareTextureCycling (uhc) boolfalseoutputinputconnectablestorable
Use Hardware Texture Cycling. Turn this on to get better performance when:
  • You are using a sequence of frames for the file textures. (See the Use Frame Extension attribute above).
  • You are using Harware texturing in the 3d view.
  • You need to "scrub" along the time line, and see the the animated texture update as you do so.

When Use Hardware Texture Cycling is turned on, you are forcing Maya to load all (or a subset of) the texture file sequence into memory. This uses up memory, but significantly improves the update speed. Use the attributes below to indicate which frames you want loaded in. If you do not load them all in, at playback time Maya will use the closest frame available.

The Hardware Texture Cycling attributes have no effect on the look of your final rendered image. They are only used to speed up what you see interactively.

startCycleExtension (sce) integer1outputinputconnectablestorable
Start Cycle Extension is the number of the first frame you want loaded into memory when Use Hardware Texture Cycling is turned on. (See above).
endCycleExtension (ece) integer1outputinputconnectablestorable
End Cycle Extension is the number of the last frame you want loaded into memory when Use Hardware Texture Cycling is turned on. (See above).
byCycleIncrement (bci) integer1outputinputconnectablestorable
By Cycle Increment controls which frames will be loaded into memory when Use Hardware Texture Cycling is turned on. If it is 1, then every frame between Start Cycle Extension and End Cycle Extension will be loaded in. If this is 2, every second frame will be loaded in. If this is 3, every third frame, etc.

During playback or scrubbing, the system will use whichever loaded frame is the closest to what is needed.

forceSwatchGen (fsg) boolfalseoutputinputconnectablehidden
Force swatch generation despite image size
filterType (ft) enumQUADRATIC_FILTERoutputinputstorable
Filter Type determines what kind of filter Maya will use when applying the file texture. Each kind of filter has slightly different properties and costs in performance.

    No Filter means just that. No filter is applied to the file texture. This is the fastest in terms of rendering, but will usually produce substandard results. Using this will probably result in aliasing artifacts (jaggies).

    Mip Map filtering is the best choice for all-round general use. Its cost is negligible compared to the other filter types, and it generally does a good job. Internally, the renderer stores a 'pyramid' of versions of the texture, each a different resolutions, and as it renders it chooses the best ones for calculation.

    Box filtering works by placing a 'box' over the the area of the texture map to be sampled, and averaging out all the samples within the box. Do not use this filter type if the file texture is to be used as a 2d projection or bump map, as it will not work properly.

    Quadratic and Quartic filters give a somewhat better quality of filtering. Like the Box filter, they sample an area of the texture, but they give more weight to samples closer to the center of the area.

    These filters approximate the quality of Gaussian, but are optimized to be faster. However, if you use these filter types, textures may "swim" or appear blurry. Do not use these filter type if the file texture is to be used as a 2d projection or bump map, as they will not work properly.

    Gaussian filtering is slower, but gives the best quality. Use this for high-quality rendering with very sharp results.

preFilterRadius (pfr) float2.0foutputinputconnectablestorable

useCache (uca) boolfalseoutputinputstorable
Use Cache is provided for situations when memory is low. If you turn this on, rendering this file texture will use less memory, but it will also be slower.
useMaximumRes (umr) boolfalseoutputinputstorable
Use Maximum Res is only meaningful if your filter type is set to MipMap. If you turn this on, it forces the MipMap to always use the highest-resolution version of the texture.
