Is there anyway to export a render with alpha option to a multilayered PSD? Example: project is on top layer with transparent background and bottom layer is background.
Unfortunately, at the moment, not in a single render operation.
I almost always massage the ground shadow in post, and also appreciate this being on it's own layer. I think that is what you are after?
So I render once, selecting BEAUTY pass only (with Alpha of course) making sure to first turn off the ground under environment properties. This is actually the "Floor Shadow" checkbox for environment properties.
Then I render a second time, turning Floor Shadow back on, but render only the "Floor Shadow" pass. This is generally a much faster pass. Also include alpha.
Now you have two images you can bring into PS, both with Alpha, and combine into their own layers. You can then do post work on them independently.
Also, 1 last point, I always do all these final renders, on a BLACK background in Visualize. I don't know that it's absolutely necessary, or just habit from other rendering packages... But rendering on a black background ensures the ground shadow alpha blends correctly (probably still have to use multiply in PS). It may work OK on non-black backgrounds in Visualize, honestly I just haven't tried.
Thanks for the Pro tip!
