This may be a wierd question, but I'm trying to render a targa sequence out of combustion that has an invisible alpha channel. By this I mean it would render full frame color channels with an associated alpha. Combustion seems to only be able to cut out the alpha thus replacing it with the matte color. I need a full frame with an imbedded alpha.
I can always use photoshop to put the alpha back in but... I'm sure I don't have to explain why I don't want to do this. (I think I might have ruined my mouse by pushing play in the actions menu 3200 times.)
Any advice is most greatly appreciated...Thnx
