Problem solved, i was wrong thinking about the black parts, in video that areas can be alpha zones, but here no, not in photoshop, please close/delete the post.

Make sure in shader you use 'opacity' if your main texture (diffuse) has an alpha channel. Also blend mode should be ob masked if opacity is used. On the texture properties of your diffuse texture (right click) make sure to tick alpha=true to avoid bugs
