Hi there, I'm Oliver from Blenders.com and in this tutorial we are going to see how to
retopo models here in Blender.
As you can see I have here a face, the one that I sculpted on the sculpting tutorial
and I have this quick and simple reference I did with the grease pencil just like in
the grease pencil tutorial, alright, so I'm going to use it as a reference for the retopo.
As I explained on the grease pencil tutorial I have a plane, here you have it, and it's
the one that I selected while painting with the grease pencil so now when we enter the
edit mode with this plane to start retopo, the grease pencil lines will be attached to
it so they won't disappear, alright, so well let's get started, first of all enter on the
edit mode with tap and now we are going to activate the snapping and select the snapping
to face and now in order to retopo we are going to activate this option, alright, and
which is for projecting every simple, every part of the object that we have selected,
for example all the vertices of the plane we have selected so they project each one
in a different part of the surface, right, if you don't activate it the entire selection
will attach to one, just one position, alright, well I'm going to show you without selecting,
right, I press G and move it and as you can see it's, you know, positioning the object
on the position of that vertex, alright, but if we activate this it's positioning the
four vertices of the plane in different places, alright, so it's projecting all the vertex
on the surface, so with this option activated we can see that this is not the better way
of having this, of doing this because we are not exactly watching what we are doing, so
what I do in this cases is go into the object panel and activate here X-ray, so now we have
over the original model the retopo model, so right now we can start retopo, so if we
select the vertex and strut for example and select the four vertices and press F to create
the face, you can see that it's projected on the surface, right, also you can select
the vertex and this is just like modeling, right, if you control click in the points
that we have in the reference, they will be created just there, like this, actually is
faster to go to the edge mode, like this, select two edges and create a face, but well
normally I find very comfortable using vertices, right, also you can do this with control and
dragging the left click button, ok, it's just like modeling, but everyone, everything you
model will be projected on the surface of the rest of the objects on the scene, in this
case the alien face, so it's very great, I love making retopo, so now let's strut this
as you can see for creating faces, using edges is faster, so you can see we
can scale rotate or move vertices and edges, selections in general and they will project
on the surface, which is what we want for making retopo, ok, also while using these
techniques we can of course add different modifiers to this object, I will show you
right now, for example we can add mirror, so now we can retopo in both sides, also we
can add subdivision surface, so now we are watching the final model for example, ok,
these are some options, but actually I prefer to don't have subserve activated at this point,
sorry, because it's easier to know where the vertices are right now, here we can strut
this very easy and fast to make a retopo, ok, so now let's try to make a retopo, ok,
also another thing that I used to do while working this way is to, you know, right now
we have the same color for the new topology object and for the original one, what I do
usually is to add a new material to the new topology object and put a different color
like this for example, right, and turn the specularity down, so now we have a better,
you know, vision of what we are doing, right, it's a great, you have a great difference
between the new topology and the original one, so it's easier to see, ok, so now let's
try to make a retopo, ok, so now let's try to make a retopo, ok, so now let's try
I think this is everything, alright, there is no much science behind this, right, just
you need to know how the modeling tools work, because this is just like modeling, but you
need to know also, well, you have to use your topology skills for doing this, you know,
knowing how the muscles of the face flow and things like that, so you can know and use
that knowledge to make the new topology follow that shapes, so they work, ok, when you are
animating the model, so I could finish this, this retopo, all this object, but I think
you already get the point doing this, also from time to time you can go out of this mode
and press slash on the numpad to isolate the object, so you have here the local view of
this object and you can also hide the guides so you can see only the object, press slash
again to have the view, now we can just select all this, here let's go to Cliping and sorry,
top x, there we go, so you can see it's pretty fast, any see once you know how the topology
works, so this is everything for this tutorial, right, I'm going to retopo a little bit more,
but I'm going to put this accelerator so you don't get bored and well as I already explained
the basics of making retopo, well you'll see how I finished this part, ok, so let's
go for it.
Ok, so here you have this part of the face already,
ready to retopo and well I just noticed that I didn't explain one thing and it's that
you can just project things, for example, let me just delete this point, well just hide
it and I'm going to create a loop right here, ok now unhide it with alt h and just merge
this and with alt j make this four sided polygon, alright so select this loop and well as I
created it with Ctrl R is not projected on the surface of the original object, so what
I can do is just press G and it will be projected, ok, maybe you won't see a big difference,
but just if you pay attention when I press G right now it's projected, ok, there we go,
so I used it right here on the mouth and all that, so now yes I think it's everything
for this tutorial and well in future tutorials we'll see how to create textures inside Blender,
so see you soon and happy blending!
