Following up on the corridor task that I had earlier completed I notice that some of the seams were noticeable, so I went back into the tile texture to see if I could find out where the repeated segment was. After I had found and fixed the problem I put the new texture onto my corridor. I am pretty happy with the outcome, however I want to add an alpha to the middle tiles in order for them to be transparent so that I can add lights and other things shining through the texture when I have fully built and texture the whole corridor.
