For efficiency reasons, UDIM substitution is not supported if image.filename is linked.
Controls how a texture repeats on a large surface. Choose between periodic, black, clamp, mirror and file. The default wrap mode is 'periodic'. The default wrap mode for tiles (UDIM, etc) is 'mirror'.
'File' wrap mode uses the wrap setting encoded in the file itself (only applies to OpenEXR files). This is useful to preserve information about how a texture should wrap without manual correction afterwors. In certain cases, 'file' mode can prevent edges. For that to work you will need to make the correct choice when you generate mipmaps with 'maketx'.
Scales the image.
Flip (mirror) the image in the horizontal direction.
Flip (mirror) the image in the vertical direction.
Swaps the axes.
Read and outputs only the first channel of the image (which is usually R). You can force other channels by defining Start Channel.
Allows you to offset the lookup channel.
Mip-Mapping Bias offsets the computed Mip-Map level from which the image is sampled. A negative value will force a larger Mip-Map level (clearer image); a positive value will force a smaller Mip-Map level (blurrier image).
An example of mipmap image storage. The first image on the left is shown with filtered copies reduced in size.
Multiplies the image by a constant.
Uniformly darkens or lightens the texture.
Offsets the image in the U direction. This offset takes place before scaling, flipping, or swapping of the S and T coordinates.
