Transparent mesh with material/texture remains black I'm using Blender 2.69. I added a plane mesh to the model (display draw type: Texture). Added a material and a alpha transparent PNG image (coordinates is UV, rest is all default). In the UA/Image Editor I definitely see the transparency of the PNG file that I put on top of the plane/mesh. In the 3D View the image is displayed on the mesh. However, the color of the plane is black, albeit the preview of the material is showing transparent. Why is that?

For test purpose I also changed the material to transparent, alpha value 0.2. The plane remains black. Why is it that I'm missing out here? 

Observation: In the Viewport Shading, "Rendered" would show the panel transparent. But not in "Textured" mode. I'm puzzled. Shouldn't "Textured" viewport shading show textures?!? Have I got the wronng expectation?

When using the blender internal render engine you need to use glsl shading to see transparency in textured mode. This option can be found in the properties panel on the right of the 3dview by pressing N.



When using the cycles render engine, the nodes based materials effect the 3dview when in rendered mode, while some nodes have a limited effect in textured mode.
