Increase the WorldScale Vector Parameter (RGB Values) > 1.0 to zoom in on the texture more.

Tools to build seamless textures in Adobe Photoshop: 1) Crop your source photo to a square resolution (1000x1000 for example). Pick a piece that doesn't have any unique attributes that will stand out in repeat. 2) Adjust the levels, brightness, and contrast to get it as even looking as possible 3) Filter -> Other -> Offset (or Scroll) with horizontal and vertical values half you resolution 4) You need to blend the cross section in the middle without touching the edges of the photo 5) Use the patch tool and healing brush in combination to hide the seams 6) Your source picture should try to keep the same lightness across the whole cropped portion but if not, you can try to compensate by changing your image mode to lab color, and using filter->Other->High Pass to flatten out the color on the luminosity channel.
