Split Mesh Seamless Texture Help

[Zivisx]

To make this brief I have a human character I need to split up for game development reasons. whenever I try to do this however the piece of his anatomy I break off becomes a darker color creating an ugly seam. I have attempted to fix this on my own in numerous way in Blender and in the game engine I am using. Any help would be greatly appreciated. Thank you in advance for your time and patience in to looking at my problem.

I have included two pictures a before and after.

You want to lock your vertex normals.
Before splitting the mesh, set shading to “Flat”, add a “Normal Edit” modifier, enable autosmooth, apply the modifier and split your mesh.
