Philywebrider, i see what is causing the white edges to show on your prop. From your screen shot the Transparancey min and max settings are at zero % they should be at 100%. If you slide these all the way over to full on, 100%, then ok the requestor the white will go away. As it stands now you have transparancy turned off on that particular prop.

As for resolution as you go above the original textures max dpi you will start to lose sharpness. One way around this is to purchase one of the fractal enlarging plugins for photoshop which allow you to enlage the texture to a higher resolution without any lose of sharpness or any pixelation occuring. You would then use this texture in place of the original.

These plugins are well worth the price if your doing a lot of print work!

Hope this helps :-)
