+===== Related to textures =====
+==== Creating textures ====
+The favorite texture format the ''.dds'' (DirectDraw Surface); it can be uncompressed or compressed with or without alpha.
+==== Textures Names ====
+Some part of the material texture are just free files:
+| X | diffuse |
+| X_n | normal |
+| X_nh | normal (rbg) + displacement (in the alpha channel) |
+| X_spec | specular |
+Other needs ''.nif'' model edit, the name is then freeform. But usually are called as the first column.
+| X_ao | detail map in the nif |
+| X_glow | glow map in the nif |
+==== ImageMagick to create textures ====
+Uncompressed: ''$ convert input.png -define 'dds:compression=none' output.dds''
+Compressed without alpha: ''$ convert input.png -define 'dds:compression=dx1' output.dds''
+Compressed with alpha: ''$ convert input.png -define 'dds:compression=dx5' output.dds''
+To make the ''nh'' we need to combine normal and displacement, one can do:
+''convert normal.png displacement.png  -compose copy-opacity -composite  'dds:compression=dx5' output_nh.dds''
+One has to be sure that ''displacement.png'' is grayscale mode without alpha channel.
