I had a client ask about making a custom stripe material. Like for a roof canopy.The easiest way is to do this is in in Photoshop I made a material. 2'x2' image size, with 1' red stripe and 1' white stripe vertical. And saved it as a JPG.
To apply it, copy that to your desktop or project folder. Drag into an open slot in Mat. Browser. Name it Stripes. Change tiling to 2'x2'. Drag material onto your object. Should be good to go. You may have to apply it to sub-object or rotate it depending on your specific object.
See example image above.
