Do you maybe have a simple example of that ugly behavior? I'd really like to check it out.
Ciao, Daniel!

It might refer to some old thread I was involved in.
If that's the case, the point in question was gelato's handling of UV
interpolation on subdivision surfaces, that used to be even worse then
PRMan pre 12, as it was a straight linear interpolation (with consequent
bad results on subDs not derivated from uniform topologies), and some
pretty bad ugliness in the lookup and bleeding on bonduaries.
It might be outdated info, but (funny enough) a lot of it seems to be
the same batch of problems ex-luna stuff had... how curious huh? ;)
