How to Create Noise Texture in Maya
The noise texture produces a grayscale image that can be used to affect the material channels.
Within the shader you have several sliders and multiple noise types. The number of possible outcomes can be overwhelming. To make the process more fun than frustrating, try using the IPR Render option.
Open a scene with a polygon plane primitive. Right-click the object and choose Assign New Material > Lambert.
The new Lambert shader panel opens in the Attribute Editor. Click the checker-box in the Bump Mapping section.
In the Create Render Node palette, select Normal, then click the Noise icon in the 2D Textures section.
Click the triangle next to Bump Value to access the noise options.
Render the top view by clicking the IPR Render icon. Once the initial render is complete, click and drag a marquee area that you wish to update in real time.
Adjust the sliders one at a time to interactively create your texture. You can also select one of the multiple noise types from the pull down menu.
