Yes agreed! 
I actually did that after i did that render. I just haven’t re-rendered it yet. However i haven’t created a seamless texture yet. Is there a way that i can do that within sketchup or will i have to use photoshop?
yes, photoshop. you may just need to trim one end, or use the “offset filter” filter/other/offset. you’d just need to affect it horizontally and the clone/touch up the vertical seam after filter has run. If you’re not familiar with it there are internet tutorials on it, there are also some online services/tools too, but I don’t think you need them for this.
Yes i’ve done it in photoshop before. Just wondered whether there was an easier alternative within sketchup or something.
unfortunately nothing in sketchup that would allow for image editing. The only thing you can do is re-map the image, maybe enlarge it a little on each face to eliminate the line, but that would be a tedious process and still would not be seamless but you might lose that line?
