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.

    $\begingroup$ If this don't work try to plug the Diffuse shader on the bottom and transparency in the middle $\endgroup$

    $\begingroup$ Seems the correct way is to have the transparency in the top shader input. Thanks for this! $\endgroup$

    $\begingroup$ I ended up using the Alpha output from the top Image Texture node for the Mix Shader node Factor input. Also, as @NeilAshleyHickman said, use the top Shader input of Mix Shader node for the Transparency BSDF node $\endgroup$

So, as @NeilAshleyHickman and @gatzkerob answer. Here is the way:

  1. Create material, then select Mix Shader in Surface section
  2. Set the first Shader to Transparent BSDF, and the second to Diffuse BSDF
  3. Click the right dot button in Color and select Image Texture, then select your transparent texture image.
  4. Goto Node Editor window (Shift + F3), and connect the Alpha port of Image Texture to the Fax port of Mix Shader.

(I got a problem setting eyebrow and hair material, then it solved)
