Indeed my normals were missing. I had an updateCallback set on my
Geometry that didn't apply SmoothingVisitor to the parents. Although
the way I do it now looks highly inefficient to me.
// g is the geometry the visitor is acting upon
auto parents = g->getParents();
for(auto x : parents)
if(Geode* geo = x->asGeode())
geo->apply(smoothingVisitor);
Is there a subcomponent of SmoothingVisitor that can be applied to a
Drawable instead of a Geode? I image it should be somewhere in the
eternals already, but this seems useful to me.
