In order for reflective objects (glass, metal, some plastics, etc) to render realistically you need to provide PWx with stuff for the object to reflect. I think it is well known that using a spherical environment is a good way to provide PWx stuff to reflect:
This brings us to my poll: How many of you knew that there is a new spherical reflective environment function in 2005? It is not in the what's new highlights for PWorks (which is weird because it is a really significant improvement), and I think it is pretty darn hard to find. What is REALLY nice is we don't have to manually split the image anymore - it takes a single image and maps it to a sphere for reflections.
Is this new function widely known? Can you find it and figure it out quickly without help (though just knowing it exists is a huge leg up)? If I am the only one who missed it, shame on me (bad Ed, bad Ed). But if it is widely overlooked by folks that need it and if they have trouble getting it to work, then SWx needs to know and correct that.
