Think you'll find it's the same... except be aware v3.8 has changed default
ambient so if you render with directive #version 3.7; it will look different
from using 3.8 in its place.
At first I thought the lathe object was thinner but its just the missing ambient
Nothing new about lathe problems, there was something about negative control
points for bezier_spline which I'm guessing doesn't actually relate to this
