CGTalk - tiling problems

I am trying to do seamless tiling with 2 different textures in maya. After editing in photoshop making sure they are spot on to the pixel "tilable" when I render it looks like there is bleeding of the color which creates a line as you can see in the picture attachment, the color of the dirt appears about a pixel on the road side where it meets the road tile again and vice versa on the left where the dirt meets dirt.... Is this a common problem in maya? can I fix that node in maya to make it not bleed?

I see that no one has responded to this question even though it has been viewed 49 times at this point. But after 2 weeks of playing with maya I've finally found the answer.

Maya's place2dtexture node by default has wrap u and wrap v checked. When doing unitize UV for environment texturing, the color of the texture space somehow picks up that bit of texture on the outer edge of the UV space. To prevent this we need to:

1. uncheck the wrap U and wrap V
2. check the mirror U and Mirror V

step number 2 ensures that the extra pixels on the edges will be the same color as the one inside the UV space since they are mirrored in 4 directions, and voila, the lines are gone

caution: there is no need to apply this step on the base textures as they are already 4 way tileable, because if you do this will create a diamond like pattern when tiling a huge area with this texture.
