When reading shadow maps in shading passes, we only need to you can also have the transparent depth in the color texture's alpha channel, I use index of object as float as conversion to A8 channel is simpler to decode.

@ebonythoma posted 2 minutes after joining, and their post is pretty nonsensical. So I'm 99% sure they're a spammer.

As to your original question, occludes have to be vectors/points, so you need a way of turning your alpha elements into a combination of points defining the element end points and then the type of occulder you want (wall, window, door, etc). I have no idea how one might do that in Photoshop since I believe everything it does is raster. But not sure even that is true. So only help I can do is to point you into trying to figure out how you can get point/vector information out of what you have already.
