I've been just starting blender these days .
I got my normal map from texture map through baking process and when I use that normal map , there are some kinds of borders between uv islands (seems like it has different brightness ..)
I searched for this problem but still I'm not sure what is the main reason causing this problem
So this is the result which I've got
If this is a duplicated quistion , sorry then .
and thanks in advance
Just let me know if .blend file is needed
