Blender 2.5 - Cycles - Dirty surfaces

Ok, a lttle dirt now. It took me some time to figure out this, and i will go straigh to the point...

- You need two objects in the scene for this tutorial, a plane and some extended cube...


- And few textures (i found somethnig on google)

image A
image B















- Because image A has to be transparent, it requires some change. Something similar to an image below...


- Next, make box diffuse color yellow...


- Select plane, press TAB, press U and choose unwrap...


- Now, node editor. Make sure that there is material output node.


- Add mix closure node, and connect to the surface.


- Add diffuse node, and connect it to the colsure1.


- Add image texture node...


- And put in image A. It should apear into closure1 image settings


- Connect image coordinate node with image texture node.


- Now, closure2. Connect in this order, glossy node, image texture, and texture coordinate.


- Here you can put image B



- Or it looks something like this



- And when you render it...


Have fun!
