The Blur and Blur Offset controls determine how a 2D map is blurred, or how
it is softened in the rendering. You can't see their effect in the viewport
renderer, only in the production renderer.
The Blur setting blurs the map based on its distance from the view. The farther
away the map is, the greater the blurring. You should always use some blurring
on your maps to avoid the type of scintillation, or aliasing that can occur
when pixel details are reduced off in the distance. This effect typically occurs
when you use detailed bitmaps viewed at a distance, and is particularly
apparent during animations. The Blur default is 1.0, which is a good setting
for most purposes.
Blur Offset blurs the map without regard to depth. That is, all the pixels in
the map are blurred equally, regardless of how close or how far they are from
the camera.
Whereas the Blur value is primarily used to avoid aliasing, Blur Offset is useful
when you want to soften, or defocus the details in a map. It's the equivalent
of blurring the bitmap in an image-processing program before applying it as
a material map.
NOTE For bump mapping on page 5382 , lower Blur and higher Blur Offset values
give better results.
Body Space
A biped limb can be put into the coordinate space of the world or an object
in the scene as well as body space. Body space moves the biped limbs when
the biped moves; if you rotate the biped's hips, the feet, in body space, move
as well.
