bump maps-how do they work?
 

hi all im just wondering for future reference for my lego scene how exactly do i make a bump map work iv tried many times but every time either nothing happens or it turns out crap

help me i need this scene done in 2 days for art class so i need help quick if no help comes ill set it up differently...

hypershade
 

use your hypershade to create a blinn or whatever material you want import your bump from the 2d file.mmb drag the bump onto the blinn in hypershade and select bump.dont keep it at its values you usually have to lower that because it to strong.to do that just right click on the blinn and select graph the network..and select the bump from there and lower the value.hope that helps.

ill try it out late thanx

make sure you have lights in your scene because it works by adjusting the normals of the geometry to give the illusion of "texture" on the object

auto
 

if its a poly or any other material after applyiny hit automatic mapping in the textures so it doesent stretch.looks alot better.

well if it's a simple object then automatic mapping will work. However with a more complex object you will need to uv map it properly to be able to paint the displacement where it's needed.
