New to texturing, my leather texture is see-through i have been playing around with leather textures and i decided to make a chair, this is a test render of it:



As you can see, the seat itself is transparent. I have read some answers on this type of issue, but they were not what i was looking for. I'm sure this has something to do about texturing.

Here is the node setup:



Green: COLOR TEXTURE
Red: DISPLACEMENT TEXTURE
Blue: NORMAL TEXTURE
You didn't pack your textures, we cant troubleshoot material problems without all the relevant textures.

Anyway this doesn't look like a texture problem, not even material related.

You have lots of duplicated geometry and overlapping vertex in your mesh, there are double faces everywhere in your seat, and your.

Enter Edit Mode in each of your meshes, select everything then press W > Remove Doubles.

Be sure to recalculate normals afterwards by selecting everything and pressing Ctrl+N
