;[http://www.answers.com/topic/mipmap MIP mapping] (MIP stands for "multum in parvo")
:A texture mapping technique that uses multiple texture maps, or MIP maps. Each MIP map is half the size of the first one, providing several texture maps for various levels of depth.
;[http://www.answers.com/topic/alpha-blending?method=22 Alpha blending]
:In computer graphics, the combining of the alpha channel with other layers in an image in order to show translucency.
:The alpha channel is an additional eight bits used with each pixel in a 32-bit graphics system that can represent 256 levels of translucency.
:(here, the base color depth is 16 bits; and there are only 4 bits for the alpha channel, so only 16 levels of transparency. [[User:Geyser|geyser]])

You can edit the TXMP data in the raw/sep file manually (although we recommend [[OBD:OUP| Oni Un/Packer]]) : there's a tutorial [http://www6.fh-eberswalde.de/user/dkriesch/onistuff/subfold/texture/texture.htm here]
