Question about Normal Maps:

I am testing out the Lighting/Shading > Transfer Maps functions in Maya 8, trying to generate normal maps. When I render out the image (with Maya Derivatives checked on), I am getting seams at the edges of the Lo-Poly Mesh no matter how high I set the resolution map and sampling quality. I have also played around with the Normal Direction and Advanced options functions as well. Here is what I have so far:

Normal Map

When I render out the object from different angles or closer up, it becomes apparent that all of the edges of the lo-poly mesh have a seam. Am I missing something obvious in the Transfer Settings? Or something I need to change in my Lo-Poly Mesh? Render Settings? Graphics Card (Lol!)

Appreciate any help you can give. Thanks.

Edit: Should I even worry about those seams? Will they show up in-game once the other maps are applied and the texture is resized?

Get rid of the hard edges, tehy're the reason its rendering the funky normal map.

Read http://www.poopinmymouth.com/tutorial/normal_workflow.htm - it's written for Max but all of the concepts transfer to Maya.
