How to get a material to map differently on different objects

I'm a newbie. I have a model with 5 wooden slabs, to make a table top. I have applied a material on the slabs and the wood grain is continuous on all 5 of the pieces. Even if I copy and paste the material, and apply the new one this remains. If I do the interactive placement it moves the texture on everything that has the wood grain. I want it to be different on each of the 5 slabs.

Even a link to a tutorial that addresses this would be helpful. I've had this not happen with other objects so I'm confused!

Thanks.

Are you using Maya's built-in wood texture, or a file texture that is a photograph of a wood pattern?

I'm not sure what you mean by 'continuous on all 5 of the pieces.' Do you mean that lines in the pattern seem to flow off the edge of one piece and then flow onto the one next to it? Or do you mean an identical pattern appears on all five pieces no matter where they are?

The first situation would arise with Maya's built-in wood texture, the second with a file texture. The most newbie-friendly way to fix both is to create multiple copies of the material (use the 'duplicate shading network' command in the Hypershade instead of copy-and-pasting), then change the values in the texture placement nodes for the copies. Look for nodes called place2Dtexture and place3Dtexture, and edit those.

Here are some relevant pages in the Maya docs:
