smooth

How Can I smooth an object. like a mesh or a sprite?
I have a motion blur effect but, it's not what I'm looking for...

Use Nair? Seriously though, what do you mean by "smooth"?

for instance if you rotate a cube you'll see that the edges are bad. I don't know how to explain it better.
higher n of polygons?

When you say the edges are bad do you mean there are 'jaggies' - if so then antialiasing is what you want which does not work reliably with all video cards under blitz3d.

.....owned.. :P, it's ok though
