DoubleSidedMaskTexture

A double sided mask texture, with a different bitmap for each side.

This node is used to lookup a float texture in a (possibly udim) bitmap file for each side. An example of use for this node is a roughness texture to bind to the Metal > Roughness parameter of the Surface material, or a metal mask to bind to the Metal parameter of the Surface material. This node is preset with a linear gamma.

Use Front Side File for front facing surface, and Back Side File for the back facing surface.

This node is compatible with udim textures, but will need you to specify manually the position of the udim index in the bitmap file name. For instance, 'c:/my/udim_texture_1001.tiff' should be replaced with 'c:/my/udim_texture_%d.tiff'.

Rotate, scale, translate

Use the 'Coordinates' tab to offset, scale or rotate the texture over the surface.

Change the input or output range

Use the 'Range' tab to control the output range of the texture.

Use an image sequence

You can directly use the '$f' specifier in the texture file name. For instance, c:/my/animated_texture_$03f.tiff assumes a 3-digits frame number.

Alternatively, you can use the 'Image Sequence' tab. In that case, you must use '%d' syntax, as for udims. for instance, 'c:/my/udim_texture_%d_%03d.tiff' to use a udim-texture with 3-digits frame numbering.
