Creating a slightly rough surface

[z00lander]

Ive finished modelling a computer and am now trying to texture it. Im having trouble getting it to look real because the surface of a some computers (like the one im making) is slightly rough and not perfectly smooth. Ive tried using a bump map but on some parts that i texture the bump map stretches and deforms.
Is there a better way to acheive this look and if not does it mean i have to make a different bump map for every part of the computer.

Use a 3D fractal texture. If you di dnot use a projection map and you simple applied an image to the existing UV of the objects then they will not map well and be uneven and stretched. Projections and 3D textrues will map proporitonately in all directions.

aaah, you have to use 3d textures.
all sorted, thanks for your help

YOu don't have to but it will make it easier for you.. You can do this with regular 2d maps but each map has to be fitted per the UV's of each patch.. it's alot of work otherwise than can be solved quickly this way.

Is there a way of somehow using a file as a 3d texture or do you have to use a projection?
I have tried with a projection but it only looks right on walls that face the same way so I would have to make 2 to do the other walls.
Any ideas?

Projections are 3D textures so you'll have to use several projections for different straight on angles
