First Channel

OffsetOffsets the first channel to be looked up.


Face Index Offset

If you have put more than one set of data into a ptex file, you can offset the index by the known amount.

Invert Winding Order

If your faces are flipped or have artifacts, your bridge application may have inverted the order, this may alleviate those artifacts by reversing the order again.


Filter

Selects different reconstruction filters that can be used during texture lookup. The filters available for PxrPtexture are:
  • 0: Nearest
  • 1: Box
  • 2: Bilinear
  • 3: Bspline
  • 4: Mitchell
  • 5: Catmullrom
  • 6: Gaussian
  • 7: Lagrangian


Blur

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

  

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


Saturation

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

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.


Missing Alpha

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


Linearize

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.
