What are mat files, bump or bum? I see them alot in downloads. What is it?

Textures are the bum files

The Bump files are Black and white. Why? Also how do you make photo realstic texture? Do you scan a person's skin in?

MAT files are a new form of pose file that will automatically load your textures for you. bump maps, or .bum files, are what gives surface detail on a model. for example, a bump map on a face will create pore detail, raised moles, etc. theyre black and white because theyre almost like a 'terrain' - the dark parts are low, and the light parts are high. just like on a real map in an atlas. theres a tutorial on making photo textures at cake1's site: http://www.cakeone.com/

Some great info at PoserArcana, too. Have fun

Hi, My 2c :) A bump map( .bum) is a binary representation of an inverted greyscale of the texture map in use, (at least that's the way they appear to me :) So to create a bump map, load the text into a paint prog, change to 8bit greyscale, invert (negative) the picture and save it out, (as a jpeg) then when you want to add it to you model: locate the file using the "browse" box in the bump map box under the one that you load the texture map with, select the jpeg and it will ask if you want to convert it to a bump? say "yes" and it will save the bump in the same location as the jpeg version. For skin set the % to about 20-25 and you're all set :) Mat files are poses that contain texture information, so you select a pose, and it sets up your textures, bumps, and transmaps with one simlple "click", (but you have to build them by hand editing the relevant pose file...) later jb
