This confuses people all the time. To expand on what Stewer said: The 'ground shadows' that you see in preview mode are just a guide. They can be turned on and off from the display menu, and have their colour changed from the little dot to the right of your window. They aren't real shadows. To get real shadows, you need all of the following: 1) Render your picture. No offence intended, but I don't know your level of experience. 2) Have 'cast shadows' enabled in your render settings (it's off by default) 3) Have shadows enabled, and set to a level > 0 in at least one light's properties (on by default, I think) 4) Have 'casts shadows' enabled in the properties of the thing you're rendering (on by default) 5) Have something to cast shadows on. Surprisingly, the Poser ground plane is not very good at this, and gives confusing results; but it should give something. Many people, myself included, use a separate ground prop. 6) Have the lights angled so that a shadow will be cast - the default light set should pretty much guarantee this. These comments apply to Poser 3 and 4, and the P4 renderer setting in Poser 5. There's probably more settings to cope with if you're using the Firefly renderer. Let us know more about what you're doing, and your Poser version, if you still can't get it to work.
