A simple float mask texture.
This node is used to perform a float texture lookup in a (possibly udim) bitmap file. 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.
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'.
Use the 'Coordinates' tab to offset, scale or rotate the texture over the surface.
Use the 'Range' tab to control the output range of the texture.
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.
