How can i activate the alpha on Blender Render? I already activated the transparency, the alpha, what i'm missing? if i see the texture preview it looks like it doesnt have a background, but when i render it it still appears.
Help please!
You need to enable it in the Material settings:



Tick the Transparency checkbox and set the Alpha value to 0.

Also be sure to make that the texture Influence affects the Alpha value:
