for example if I have a geom::Cube, and I want to add a custom vec3 attribute , What is the best way to do that? Im looking through the geom::Modifiers and I see
Remove but no add? Do I have to subclass form geom::Cube and override
uint8_t getAttribDims( Attrib attr ) const override;
AttribSet getAvailableAttribs() const override;
void loadInto( Target *target, const AttribSet &requestedAttribs ) const override;
that seems like too much work?
