Like all texture style nodes, this node takes a manifold which describes either a 2D or 3D domain to apply a the texture to. The default behavior if no manifold is attached, is to apply over the s,t domain defined on the geometry.

Provides access to texture files. Texture atlas format files can be read in UDIM (Mari) format, ZBrush, or mudbox format. This plugin also supports Rtx procedural texture plugins.


Input Parameters


The filename of the texture. This parameter must be supplied.

To use an image sequence, Typically, you'll use string substitutions to construct texture map references by embedding the frame number in your favorite representation. Here's an example:

(For Maya)   $PROJPATH/sourceimages/flapping.<f4>.tex
(For Katana) '/images/flapping.%04d.tex' % frame
(For Houdini) use $F $F3 in the file name or Houdini expressions,`padzero(3, $F)`

It's best to avoid special characters, diacritics, and spaces in your file path as these may not be resolved correctly and result in the texture failing to render.


First Channel Offset

Offsets the first channel to be looked up.


Atlas Style

If you specify an atlas style, the filename must contain _MAPID_ which will be substituted automatically according to the surface parameterization and atlasStyle. A Mari UDIM example for the first UV tile would be Diffuse1001.tex where "1001" replaces _MAPID_ in the texture filename.


ValueApplication StyleExample (Diffuse_MAPID_.tex)
1UDIM (Mari)Diffuse1001.tex, Diffuse1002.tex, etc.
2UV Tile Base-1 (Mudbox)Diffuse_u1_v1.tex, Diffuse_u1_v2.tex, etc.
3UV Tile Base-0 (Zbrush)Diffuse_u0_v0.tex, Diffuse_u0_v1.tex, etc.

Users should avoid negative texture coordinates for all atlas texture workflows

Invert T

Inverts the t parameter for the texture lookup.



Selects different reconstruction filters that can be used during texture lookup. The filters available for PxrTexture are:

  • 0: Nearest
  • 1: Box
  • 2: Bilinear
  • 3: Bspline
  • 6: Gaussian
  • 7: Lagrangian



Specifies how much to blur the image retrieved from the texture file.


Mip Interpolate

Selects whether to interpolate between adjacent resolutions in the multi-resolution texture, resulting in smoother transitions between levels.


Missing Color

If there is an error opening the texture, use this color.

.0 0.0 1.0

Missing Alpha

If there is an error opening the texture, use this alpha.



Apply the reverse sRGB transform your texture. If you are painting textures in sRGB space (default for most paint packages) but viewing your data in data linear space, your textures will look washed out. This will apply the sRGB transform to your texture, which should make it appear visually linear again.



Provides the domain over which to apply the texture. Defaults to s,t.

Adjust Output

Color Scale

A multiplier for the color values in a texture, can be used to adjust brightness or manipulate individual color channels

Color Offset

Apply an offset to the result, shifting the colors of the result


Increase (greater than one) or decrease (less than one) the saturation of the texture result

Alpha Scale

A multiplier for the alpha channel, useful when the alpha is used to drive a parameter

Alpha Offset

An offset for the alpha channel, useful when the alpha is used to drive a parameter

Advanced Settings


Bias mip selection chosen for rendering to either a higher (negative integers) or lower resolution (positive integers) selection.


Clamp mip selection to a preferred maximum level. This may prevent the highest resolutions from being rendered depending on your selection.


Sets texture filter to Box (inexpensive) on indirect hits instead of the selected filter used for other visible effects.



Output Parameters


The filtered color result. Note that all results are looked up starting at the startChannel offset.


The R channel result


The G channel result


The B channel result


If alpha is present and resultRGB is connected it returns the channel after RGB. If RGB is not connected it returns the first channel.
