When modelling an object with lots of different parts.
Is it better to, have one mesh with lots of edge loops, and all the parts extruded out of it.
to have separate simple meshes, with less edge loops, that are not joined, but are grouped by say, joining the meshes or parenting or something.
you want to create a door. you want to keep the door simple, but if you want to add a handle and letter box, then its going to complicate the mesh by adding more loops, but the advantage is, its all one object.
your other option is, model a simple door, leave holes for letter box and handle, then create separate objects, which will have a higher poly count,then insert them in the holes. a rectangular hole for the letter box, in which slots the rectangular letter box.
Option 1, I imagine being better for simulations, like the game engine, I imagine if somethings not connected, then it would fall off?
Option 2, would be an cleaner, more suited to still images. I dont know if a group object would animate or be usable in physics sims.
so, is this something you are conscious of when modelling? Is it better overall, to subdivide everything from one cube, or to have seperate grouped/parented objects?
