Hi, i’ve got a little problem with texture on my model imported from blender.
There’s some artifacts on body and arms (only).
That how it look like in unity:

And how it look like in blender:

Settings of material and texture:


Thank you in advance for your help 
It’s blender export problem. try some different settings during export
The problem is i tried two methods: Import to unity .blend file.
And firstly export from blender to fbx file and then import to unity.
The result was the same 
I’m working with Maya. In Maya when model has two different UV sets, This problem caused.
UV set1 used as model main uv mapping and uv set2 used as lightmapping uv. You need to map model uv in uv set1.
Changing UV set in Unity Standard type material didn’t work. In blender i don’t see any other UV maps.
That’s a little bit frustrating 
If you want, send me your model to test it
