Solved: PNG Textures with Alpha?

Would someone kindly point me to an example with a simple texture that uses png with alpha? My goal is to use a texture with a png with alpha over a material with a basic diffuse color. The color should be visible through the transparent sections of the image.

When I try this, the transparent sections of the image appear black.

Thanks,
Jem

Ok. I figured this out. It was a noob problem. The answer seems to be that this requires two materials. One material for the base color and a second material for the alpha blend. The PNG with alpha is applied to the alpha blend material and that is rendered in front of the base color.

Could be a better way, but this works well.
