This question may have been asked before, but how do I create shadows in DS4(Advanced) by using a photo background to insert Vicky into instead of a 3D modeled environment?

Take for instance the Sand & Water Beach photos below, or any that I have taken myself. Here's an example of the S&W package available from DAZ:

If I understand correctly, they are just regular 2D photos someone is offering for DAZ users as backdrops.

I have been practicing poses with my Vicky4 and using some of my own vacation photos and a few work pics too using backdrops under Edit/Backdrop. But even with Shadows & other things all turned ON in DS4, I'm not getting any shadows on the floor or walls or bed, beach, pool, etc. I also need reflections too. But that's another problem for another day perhaps. Unless you want to add some info there too. I won't discourage it.

Use DAZ3 but sure it will be the same. Open a wall plane...Surface add the background as a texture to it. It then should reflect lights etc. Also you may have to tilt the plane to get the correct effect...Works for me.

I wish there was a tutorial video for this sort of thing.

I don't know anything about "wall planes" or adding surfaces.
