What do you need to know about bump mapping?
When you want to use normal mapping (this is what you actually mean by “bump mapping”) you need two additional vectors for what you intend to do: The tangent and the binormal. Tangent and binormal are calculated from the geometry normals and the texture space of the “bump map”.
Is it possible to combine normal and bump maps in Maya?
This simple tutorial demonstrates how to combine both normal maps and bump maps together in one Shader. If you add a normal map in Maya to a shader, it will by default, connect itself to the Bump attribute. This technique can also be used for combining two normal maps together.
How to calculate tangent and binormal in shader?
Tangent and binormal are calculated from the geometry normals and the texture space of the “bump map”. I did explain how to do this in →my answer to StackOverflow question “How to calculate Tangent and Binormal?”
For many surfaces, bump mapping is perfect—fabrics, craggy surfaces, wood grain, or even metal vents, provided the camera doesn’t get too close. To see a bump effect, the material usually needs to have at least a minimal amount of shininess.
How do you make a bump map in Maya?
Because bump maps are determined with values taken from a grayscale image, you can often take the color version of a texture you have and modify it to become the bump map, as shown in Figure 8.34. After you have a bump map, all you have to do is set the placement so that it lines up with the texture already applied to the object.
How to get rid of bump mapping in hypershade?
In Hypershade, MMB-drag the pottery material to the bottom tab area. If the bottom tab area is cluttered, you can clear it by selecting the materials you are done with and clicking the Clear Graph button (refer to Figure 8.1 ). Chapter_08\\ch08tut05end.mb
