How to Create a Procedural Texture in Maya
Procedural textures are generated mathematically and don't rely on bitmapped images. This means that they can be scaled without falling apart and because of the calculations they can become processor intensive.
In Maya you have several options for procedural textures. They include Bulge, Checker, Cloth, Fractal, Grid, Mountain, Noise, Ocean, Water, Brownian, Cloud, Crater, Granite, Leather, Marble, Rock, Snow, Solid Fractal, Stucco, Volume Noise and Wood.
Add a NURBS sphere to the workspace by choosing Create > NURBS Primitives > Sphere.
Select the sphere, then right-click the sphere and choose Assign New Material > Blinn.
In the Attribute Editor, blinn tab, click the checkerbox next to the Bump Mapping slider to open the Create Render Node panel.
In the Create Render Node panel, 3D Textures section, click the Marble button.
Open the Attribute Editor, marble1 tab and change the marble settings.
Add color to your shader, then click the Render Current Frame icon to see the new shader.
Trouble Finding a Particular Tab?
It may be a challenge to find a specific tab in the Attribute Editor. One trick is to graph your object in the Hypershade panel (see Graph Material in Hypershade). Another option is to use the Focus menu in the Attribute Editor to select the hidden panel.
Lowering the Bump Height
To adjust the bump height, click the bump3d tab in the Attribute Editor and adjust the Bump Depth value.
Use the Same Texture for Multiple Nodes
In our final render (Step Six) we applied a Marble texture to the Color channel. Both textures had the same Marble settings. It is a quick way to build a complex texture where all the channel details have consistent registration.
