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

enter image description here

So this is the result which I've got

And this is a normal map enter image description here I just assume that process which I get normal map from texture map made some problems ..

If this is a duplicated quistion , sorry then .

and thanks in advance

Just let me know if .blend file is needed

  • $\begingroup$ Was the normal map baked in tangent space? And is it now being mapped in tangent space? Those settings need to match up, otherwise you will get shading problems at the seams. $\endgroup$

  • $\begingroup$ I baked in tanget space and it 's also mapped in tangent space .. I may guess something wrong in my uv map . Anyway I changed tangent space to object space when baking, and it seems like the problem is solved . However still don't know exactly what the problem is. My baking process is this - 1) import texture map to a plane and subdivide it , 2) add decimation modifier and subdivision surface modifier 3) add new plane and bake normal map from previous plane to new plane . Any problems during this process?? $\endgroup$
