Photo Renderings don't save an alpha channel

Am I right in saying that when you generate a photo rendering in AC 9 that there isn't an option to save the background as an aplha channel?

This is something Strata 3d CX does which saves a bit of time when montaging into a site photo and I suspect I'm trying to endow AC 9 with abilities it doesn't have as a result of using Strata quite a bit

Hmm. I think you may have come across a bug.

There is a check mark for both the Internal and LW engines to use alpha channel for transparency for the background image.

But: with the internal engine in 9.0, if I check this box, then my model is not rendered ... I only get the background (and no alpha).

With LW, and this box checked, the result is the same as if the box is unchecked.

Anyone?

I notice this, too.

Same with AC 8.1.
Try AC 6.5 - it worked then...
