Different Image types and Alpha Channels

Hi,

I'm looking for an option to enable alpha channels. The PNGs I'm saving in don't seem to include any alpha information.

I've noticed that on the Spiderbot video on this site that in Octane he has a completely black background. Would this give me the alpha data that I need? If so, how do I get that black background?

Thanks for reading,

alpha is not supported yet in renders, but is coming.

You can make a luma matte, to create an alpha, but that is your only option right now, and there's a post somewhere on the forums here, on how that's done.
