Resized parts show much more specularity. You can kill it in the ".mat" files put specular to 0

But that's just stupid way to fix the problem. Because the prop was rezised, the vertex normal lengths were also increased and normals are the main thing that determine how surface reacts with light (along with surface material). Longer normals -> wierd lights. The normals need to be normalized (set back to unit vector).

Yes, it is stupid. But it is fastest, simplest and everyone can do it with ease and without much knowledge of the matter.
