According to my/our (Ralf's and mine) experience loosing the material
type was usually caused by the point-in-polygon droppping the centroid
into the wrong polygon.
The "terragear-cs" history contains a 'robust' point-in-polygon routine
by Ralf Gerlich which might me worth investigating. But there's a
price to pay because the mentioned method might drop the centroid into
areas of the polygon which later are getting eliminated without
topologically correct handling of the centroid. To put it into
different words: If polygon massaging occurs in a topologically safe
manner, there's a robust point-in-polygon available.
Cheers,
Martin.
