I Just found bump node on blender

Its been a while since i play with my 3d program blender. Last time i posted here, i was searching a way to use bump map with blender. at that time i don’t know weather bump node for cycles rendering engine already exist or not... most of the tutorial i find online was a quick hack for using bump texture into cycles renderer. if it was exist at that time, i probably didn’t notice the bump node that cycles had. Today while i was playing with my blender, i notice that there’s a bump node under the vector subsection of blender node for cycles.

After i found that bump node, the next step is testing it on a scene. Then i remembered that a while ago i had this scene where i imported genesis character from daz3d program. For people that only use 3d for a hobby like myself, daz3d is a program that really help alot.

So... after i open that scene, i do a quick render test to see how bump node really work in blender. Here’s the result:

-partial render of a lips of genesis character under blender, using cycles rendering engine without a bump map...

- Now this is the result when i apply bump node into the shader node...

The bump node can be found under the vector subsection(Add>Vector>Bump)

Not sure that this is the correct way to use the bump node but here’s how i setup my bump node:

The height input for the bump node come from image based texture map which coverted to black and white image using coverter node.
