tez12,

Are you using Poser 6? My experience with P6 is there is a bug that only involves reflections of the upper part of sphere when you are inside the sphere. I have no idea why this happens, but if you're using depth-mapped shadows then it never renders reflections correctly unless I enable "Reuse Shadow Maps" and I'm not using a freshly generated shadow map. 

What I do is enable shadow map reuse, then I start a render. As soon as the shadow map is done and the actual rendering starts, I cancel the render. Then I can start another render and it looks right. Thereafter, unless you recalc the shadow map, everything is fine. If you move the lights or props and want a new shadow map, you must once again start a render, let it finish generating the fresh shadow map, and cancel it. Then render.

Meanwhile, if you want me to send you the scene file, I will. However, even compressed it is too big to post here, so if you send me an email through rendo, then I'll have your email address and I'll send you the file.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
