Hello. I'm a new user of Poser 11. Recently I learned how to create a skydome using 3rd party addons like EZDome. But what do I do when the 'ground' of the skydome isn't on level with the default level of the Ground? For example, I set up an urban night scene (using a skydome) but the street level is much lower than the default ground level. The other question is how can I create an invisible floor just to simulate the subject's shadow? The subject is in a skydome so the HDRI is actually wrapped along the interior of the the dome.
