transparent renders?

hey people

just a quick on is there a way of rendering transparent backgrounds? for example doing some web graphics such as 3d buttons logo’s etc i want to render as i transparent img such as a png loosing the background.

Can it be done internal to blender or do i need to use photoshop?

thanks in advance

In the render settings, select the output format to one that can have an alpha channel (eg .png), select RGBA (A is the alpha channel), set to Premul and render.
