Material with transparency affecting everything behind it

I created a material with ZTransparency, and set alpha to 0.
On the texture for the material, I selected “Use” under Alpha.
Then the material has both the color and alpha channels selected below (both set to 1.0).

When I render the scene, it looks correct.

But while editing the scene in “Material” view, the transparency seems to affect the mesh underneath it as well

Basically, I’m trying to fit some hair meshes to a head mesh. So I need to be able to see both meshes, and view it in material or texture mode. (the head should be visible under the hear, but it’s not)

Any obvious noob mistake?

Sounds like you’re in the blender render engine?

Under object properties select the Transapency check box. That will force it to be drawn after non-transparent objects. Also if you have multiple materials on an object, move the transparent materials below the others.

That fixed it! Thank you!

You’re Welcome! What happens is the scene is drawn using a Z-Buffer; Everything is drawn except what’s further away than what’s already been drawn. By marking objects as transparent, or drawing transparent materials last, it ensures that anything behind them are drawn first.
