Bump Mapping.....That old chestnut.

[+russouk2004]

Could someone do a "For Dummies" ,Tut for making bump maps,I think I have the gist of it but not 100% sure.

thnx in advance.

My way to make bumpmaps:

after finishing textures in photoshop (layered) I save them as new file

then I delete all markings, weathering, colors etc.

from panel lines and rivets I delete all layers but the basic one (delete all shadows and 3D effects)

panel lines should be black or dark grey, rivets should be light grey if they are above the surface

or medium grey if they were on the surface.

Then I add basic collor layer under that all - RGB 128/128/128

Some panels are above the surface make them lighter

If you want to deform surface between rivets (sag the surface)

make transition from grey-white-grey to bulge the surface

or grey-black-grey to squeeze the surface

if you have all that save it as BMP and then apply some plugin (Nvidia for Photoshop) to make

it "blueish". I dont use DDS because transitions arent smooth in that format

I pretty much do it like that as well, then use xNormal instead of a plugin. Basically...anything less than 128/128/128 will show as a 'dimple' and anything brighter than 128/128/128 will show as a 'bump'. The farther away from 128/128/128 it is, the more pronounced the effect is.

nDO rocks.

Got shadermap pro and getting to see how it works,early yet but its easier than I thought lol.this is just a trial run.

I didnt actually expect it to work 1st time lol.actually it also adds some good gloss to the skin.
