White lines between objects in render I am kind of new to the whole animation aspect and in fact still in high school.
 I am trying to make a Minecraft character rig and I want to make some 3D hair. I did not know how to quite make it so I kind of when just did something pretty simple. It isn't the greatest in any means, but any how the point is every time I render it white lines show up between objects or joined objects. I don't know how to fix this and would like help (a picture is posted below of the problem).
It's caused by lack of bleeding in UV set, which will show poor result when sampling.

To solve this, just leave some room for the border pixel with the same color (that's what bleeding used for).
