i am using std::set and i think that is why i am getting the template error. auto it = vertices.insert(command->vertices[j]); I'm not sure though

1>        with
1>        [
1>            _Kty=ORE::Vertex,

1>            _Alloc=std::allocator<ORE::Vertex>
1>        ]```

#

which is that line

Does ORE::Vertex overload the < operator?

no

#

Well that is your issue

#

std::set uses < to organize the elements within a set

now it says message : see reference to function template instantiation '_OutIt std::transform<std::_Vector_iterator<std::_Vector_val<std::_Simple_types<_Ty>>>,std::_Vector_iterator<std::_Vector_val<std::_Simple_types<_Ty>>>,ORE::SpriteBatch::End::<lambda_1>>(const _InIt,const _InIt,_OutIt,_Fn)' being compiled 1> with 1> [ 1> _OutIt=std::_Vector_iterator<std::_Vector_val<std::_Simple_types<uint16_t>>>, 1> _Ty=uint16_t, 1> _InIt=std::_Vector_iterator<std::_Vector_val<std::_Simple_types<uint16_t>>>, 1> _Fn=ORE::SpriteBatch::End::<lambda_1> 1> ]

#

nvm fixed it
