changing black uv texture areas to transparent in cycles So I've been using WoW model viewer to export .obj files into blender. Everything works great up to the point where a UV texture that's created by WoW model viewer has any transparency on it. In the UV map this is shown as a black area, and looks terrible on the model itself.

After looking it up on Google I found an archived post in regards to the alpha is the black area, however I don't understand how this translates and the post itself had images that were broken links, I've still yet to find anything on Google close to this archived post.

Just starting up with Blender I am struggling to find where to resolve this transparency issue, as it's making certain models look terrible.
You have to make the following Node set up: Connect 'Mix Shader' node in the 'Material Output', then use as your first shader 'Diffuse' and plug in it your 'Image Texture' node, now connect 'Transparency' Shader as the second shader, and finally to the factor connect your 'Image Texture' once more.
