Export Transparent PNG

This is a quick tutorial on how to render an image with a transparent background.  The idea behind it is that anything that isn't modeled, essentially all parts of the "sky" that are rendered will be rendered as transparency in the PNG.  I'll go over both methods for Cycles and Blender Internal.

For Cycles, set the PNG format to RGBA, and way down in the Film panel enable Transparent.  

For Blender Internal, again set the PNG format to RGBA, but this time set the alpha in the Shading panel to Premultiplied.

When you render, the sky should be black, and when you save the image it will be transparent, as shown with the basic cube setup.

  1. How do you get to the Output panel in the first place?

    1. Good question. In both cases they are under the "Render" tab, which is the icon that looks like an old fashioned camera. The interface may have changed depending on what version you are using.
