Question about Normal Mapping

Krisonrik

I have never used Normal map on my model before. Just wondering, is Displacement Map under the shader notes the same as normal map?

No, they're very different. A displacement map will actually subdivide your geometry at render time. A normal map is a more advanced form of bump mapping. It won't affect the slihoutte or geometry of your model at all. Just how light bounces off of it. Very generally speaking, displacement mapping is used in rendering, and normal mapping more commonly in realtime applications.

Thanks a lot. I was wondering why add displacement map will make rendering so long. Do you mind show me an example of what a displacement map should look like? I know what normal maps look like.
