How to Create a Bump Texture Material in Maya



Using a bump map gives the surface a bumpy appearance. It doesn't actually distort the geometry like the Displacement shader. The illusion can be lost by viewing the object's edge on an object such as a golf ball with dimples.


Step One

Open a scene with a polygon sphere primitive. Right click the object and choose Assign New Material > Lambert.

Step Two

The new Lambert texture panel opens in the Attribute Editor. Click the checker-box in the Bump Mapping section.

Step Three

In the Create Render Node palette, click the Brownian icon in the 3D Textures section.

Step Four

Click the triangle next to Bump Value to access the Brownian options.

Step Five

Select the perspective view and click the IPR Render icon. Once the initial render is complete, click and drag a marquee area that you wish to update in real time.

Step Six

Adjust the sliders one at a time to interactively create your texture.

Building a Texture

Consider adding a complex color shader to the color channel (i.e., Crater) to add multiple layers of depth to the texture.

Adjusting the Bump Height

Too adjust the bump height, go to the Attribute Editor, Bump tab and change the Bump Depth setting. For a subtle bump effect, try values less than 0.1.
