texture mapping question

[crackhead]

i have bought a load of textures from 3d total as i was having a hard time finding the right textures on the net. so i have lots of skin textures an stuff for when my model of a character is done. and i have the bump maps so say i started making the texture and painted part of a texture of a scar onto the skin how would i put the bumpmap of the scar in exactly the right place on the bump map of the skin? or would i just have to make a bumpmap of the actualy skin when its finished n just ignore the bumpmaps i got on the cd? also if anyone wants any of the textures ive got add me on msn at [email protected] i have aged and stressed , fantasy and humans and creatures. u can get some of them on limewire but there 30 pounds each to buy.

i dont entirely get you, but i would suggest UVMapping - it can certainly be done this way.

Yea, the proper way to texture models for games is to UVW map them, then export the map in a non compressed format (tga), then load it in photoshop, use the textures in your texture pack to paint on that tga, save it. Then to do the bump map, take the texture map as a reference but instead of painting colors, use only grey tones to tell where you want bumps. Save as a tga.

Of course I didn't give alot of details on the process of unwrapping because you can find alot of tuts about that on the net.

yeh i know how to uv map and everything. for the bump map can you not just take the texture and make it black and white and invert the colours?

 

[Some0ne]

if you make it black and white there will be no colours. well, except black and white
and i dont quite get what you mean/want to do.

Yes it will "work" but they won't look good. The purpose of bumpmaps is to give an impression on dept on the surface so you will paint in white everything you want to be bumped. In general it's true that the texture looks like the bumpmap but you should only use the texture map as a reference, to know where you need to add bumps. But technically yes it will work if you use a copy of the same texture (greyscaled).
