I'm trying to render a scene with transparent png. The scene is actually imported from a .obj file (with another .mtl file), which should technically applies the transparency for me.
^ It does shows transparency in the viewport.
^However, in the rendered result it shows a black background instead of transparent background.
I have no idea why, and the alpha value is already at 1.000. Any idea?
I'm using Blender 2.67, Blender Render. (not Cycles)
If you need a transparent background, in Render tab you need to change:
If you need a transparent texture, you must activate transparency in the material and lower Alpha value (Alpha=0 is fully transparent).
For example:
Alpha to transparent, but it didn't work. The texture remains black.

In the material tab go to "option" and uncheck "traceable" after that it should work and the transparency should be there .
The "Alpha" you changed, is the Opacityvalue for the whole texture. If you turn this down everything would become transparent.
Sometimes when you use a lot of pngs you have to raise the transparent max bounces under render properties-Light paths-max bounces-transparency
