A bump map to normal.
This node is used to perform conversion from bump map to a normal, and is used as input to the various Normal inputs of the Surface material. An example of use for this node is a bump map to bind to the DiffuseNormal 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 'Amount' parameter to control the amount of bump
Use the 'Offset' parameter to control the neutral value of the bump map
Use the 'Coordinates' tab to offset, scale or rotate the texture over the surface.
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.
