Re: seamless discontinuity angle across multiple polyobjects

["Tim Leydecker" <BauerOink(at)gmx.de>]

Did a quick test following Matt´s post with a cylinder and a
flatblueish normalmap, the results are a bit better than without
the map but that could just be me and my weary eyes...

Admittedly, a simple cylinder with two, three shards extracted
is an unfair example, a more complex geometry probably
would hide the seams more but a cylindrish shape is what I need,
a polished, even cylinder/tube...

I´d really wish there´d be a toggle to interpolate normals angle
across seperate meshes/intersections. Could allow for cool effects.
