How to get the boundary lines to show up

[Anonymous]

I created this tiled floor however some of the lines aren't showing up. I was wondering if anyone can figure out where I went wrong?

Realistic view only show the textured defined by the Material > Appearance tab. That material has a repeating small pattern but no tile score lines. You need to use a different image with the tile score lines for the texture of the floor material.

I'm seeing the lines exactly the way they appear in your image. They are faint in the image as well.   If you want them more accentuated, try use a high contrast, black and white version of the same image as a BUMP image.  Also, is your tile scaling correct? Based on the scaling you have, the individual tiles would be represented as approximately

3-3/4" square.   If the tiles are, say 8" square, then the scale should be 20" in both the x and y directions. No?
