On
the Detail tab, select Unweld. The reason
this step is important is because in order
to have another object break apart this
glass window, the multiple polygons you
just created can??™t be attached to each
other. Figure 14.21 shows the tool.
The adjacent polygons of your model
share common points and side segments;
in LightWave lingo, these polygons
are welded together. The Unweld
command converts each selected polygon
into a discrete, self-contained

object with sides and vertices all its own. Applying the Unweld command to the
window surface will allow the dynamics engine to shatter the window by animating
each triangular segment as an independent ???shard.??? If you did not unweld the
points, the dynamics engine could only move or push the entire window object,
even though it consisted of multiple segments.
Note
18. After you??™ve unwelded the points, save the object. That??™s it! Your window is created.
If you want, select various polygons and apply different surface names to them.
