Building long wood material

[crob1692]

hey Keyshot community can someone please help me? so iv been given a task at my work to create keyshot renderings of there composite wood boards. also i use solid works to build models. iv built textures using photoshop before but never a big long board. The boards measure 20ft x 6in. my question is how do you go about building a material that long without repeating the texture and getting seems throughout my board. Im using and image of the board that is roughly 24in long. iv gone about making a PS file that is 20ft x 6in build the file size is huge! there has to be a better way can someone help? hopefully this all makes scene.

There is a procedural wood texture in Keyshot, try looking for some examples of that being used.
