Seamless textures UV mapping

[Chonkinator]

I am new to blender and I have just made a UV map and added a texture onto the mesh. But i noticed that that seams are visible and it looks really ugly. Does anyone know how to get rid of the lines and make the texture appear smooth? Edited February 2, 2013 by av64760

It really depends, because usually a mesh has more then 1 texture... Skins for example, they rely on 4 textures, each and everyone of them could potentially cause seams:

 

1. Diffuse: this one is what gives the texture for the skin

2. Normal: this one allows to "cheat" the light, by changing the direction of the light in a low-poly mesh. Usually normals require you o have a high-res map, that allow you to bake a texture to simulate the light direction on a low-poly as if it was a high-poly.

3. Specular: changes the glossy/shiny aspect on a surface

4. SubSurface: emulates the color change on the skin, when light hits it... for example, ears, since they are thinner, some light is able to pass through it, changing its color aspect

 

There are many other textures that might be involved in a 3D mesh, depending on each case

 

Every single texture must be seamless, and if possible, baked in a 3D app. You can try to blend the textures in 2D apps like PS/GIMP, but the results are never as good as if you baked them in 3D.
