I havent built
loads of heads so I'm no expert :) and this is not the only way to do
stuff its just the way I did it this time ;-). Its meant as a guide to
give you some ideas on how to get that first head modelled. Its not
fully finished yet and this part only deals with the bulding of the
face, the top/back of the head, neck and ears etc will be added as I
write them, look out for news on my main page!!
I found some decent head pics on Fineart.sk
and in Cinema 4D I clicked 1. EDIT on each viewport and 2. Chose the
background pic and set its size the same as the image. 3 Also I click
SANP SETTINGS tab and disable WORLD GRID by unticking it!
Ok first thing is to add a POLYGON OBJECT
the add some points (hold CTRL and click to add points) outlining the
eye, I move the points in the side view as well to make them follow the
eyelid, then I select all the points 1. click STRUCTURE and 2. COPY and
3. PASTE (copy of selected points) and 4. I SCALE the points up making
the outer eyelid, its a quick way of copying points and keeping their
shape.
Heres where the BRIDGE tool comes in handy,
press "B" and drag 1-2, 3-4,5-6,7-8,9-10 to create all the faces along
the top of the eyelid and press ESCAPE to break off face building, then
drag 11,12,13,14 to build the bottom faces along the eyelid....
I added 4 more points for the eyebrow in
POINT MODE and moved them in each view to fit the reference pic as you
can see. Use the BRIDGE tool to build the faces up from the top eyelid
edge......
1. Click and 2. Drop in a SYMMETRY object,
this will allow me to build one side of the face and automatically
mirror and weld the other side....
1. Drop the polygon object into the SYMMETRY
object and the eyelid will be mirrored, its usually in the wrong place
so 2. SELECT the AXIS icon and 3. move the AXIS of the SYMMETRY object
to the middle of the face 4. here, this mirrors it perfectly
1. Make sure SYMMETRY is selected and if the
object is mirroring the wrong way 2. CHANGE this to tell it which plane
to mirror the object in, for this ZY works....also 3. This is the
tolerance of WELDING the seam down the middle between the two halves.
1. Select SYMMETRY again and 2. The lower
the number the closer the points down the middle have to be to snap
together and weld, so I set it bigger at 1m instead of 0.01m...3. As
you can see all the points down the middle get autowelded.....nice!
1. I now drop in a HYPERNURBS object and
drop the SYMMETRY into that!! 2. RightClick the POLYGON object, 3.
Choose NEW TAG and 4. Choose PHONG TAG from the menu, this will smooth
the faces....
OK I'm constantly dragging the SYMMETRY out
of the HYPERNURBS and dropping it back in, this is because the faces
are easier to see sometimes when they are not smoothed. 1. I need some
more detail in the top eyelid so I Select the faces and 2. I make two
cuts using "K" the KNIFE tool, 3. I also weld the points that are close
together just to tidy up the mesh, then 4, I move the new points
inwards to create a more definate line in the top eyelid....
OK now I added some more points under the eye and moved them in both
views to try and follow the reference pic, I built the faces using the
good old BRIDGE tool and tweaked the points a little more...I also
added some points down the nose and built the faces...
1. POINT MODE, 2. the MOVE tool and 3. I
hold CTRL and click to create some more points to build the forehead
faces with, as you can see 4. I drag the POLYGON object out of the
SYMMETRY to see it in plain flat polys, then drop it back in to smooth
it!
Build the faces for the forehead and its
back into POINT mode to push and pull points around, spinning the 3d
view, checking in all views and constantly seeing if it looks right...
In the left half of this pic it shows 1. The
faces above the eyebrow I selected and cut using "K" the KNIFE tool,
then I moved the points inwards a bit just to define the eyebrow
slightly.....
Added a load of points and built some more
faces and generally spent about 10 mins pushing and pulling points
again and watching all the views to try and position them correctly
Again more points a few more faces and more pushing and pulling of points in POINT mode.
I hate making noses :) anyway this is how I
did it this time.....1. select the side of the nostril and EXTRUDE a
bit and scale it, 2. POINT mode and lots of tweaking to try and get the
shape right, 3.I cut some faces in underneath and tidied it up using
weld, then I select the faces that make up the nostril hole and 4.
EXTRUDE upwards into the nose to create the nostril.....
It still needs more tidying up, I made a few
more cuts and moved around POINTS to try and get something that looks
vaguely like a nose, its hard to explain since its not something I know
a lot about, better get sketching and studying I think :)
I added some points to create the top lip
and I built the faces with the BRIDGE tool and moved the points in both
views to match the ref pic, then 1. I selected the points along the top
of the toplip and 2. STRUCTURE and COPY, 3. PASTE the new copied
points, I move them up and in a bit. I use the BRIDGE to build the
faces and the also the faces to attach it to the underside of the nose
and cheeks....
As you can see I create faces to join up
with the edges of the rest of the face, again a lot more tweaking of
points goes on now and all the time and once its finished another hour
at least will be spent tweaking points and tidying up to try and get it
to look right
1. I add some more points and build the
faces, I move all teh inner points of the chin outwards a bit to give
it a bit of depth, and 2. I build some more faces to attach the chin to
the mouth/cheeks etc...again more point tweaking as well :)
I add some more points following the
chinbone in the side view then I move each one in the front view as
well, I build more faces using....guess what?.....the BRIDGE tool
Heres a quick render of it so far, MORE
TUTORIAL parts will be added as I write them! I hope you guys out there
like this stuff and find it useful, if you do stop by Psionic3d.co.uk and hang out on the forums with the rest of us 3D/4D maniacs ;)
