Floor Joins

Hi there,
I am creating a 3D render and have added my flooring image as a new material. When i add it onto my render, you can see an outline of the flooring material, so the flooring looks like a grid, rather than one entire surface. How do i remove the box look from around my flooring image to make it one seamless surface?
Thank you so much,
Jo

The texture image appears to have a thin white border around it and it also appears to be darker at one end than the other. You should open the texture image in an image editor and remove the white border. It would also help to edit the image itself to even out the shading and remove the barker part at the one end.

Note that since your floor area is larger than the area your texture image covers, it will necessarily repeat so the knots and other features will still repeat so it won’t really be seamless.
