Focus 1 - Creating Dynamic Balloons With New Aerodynamics & Morph Camera in Cinema 4D R14 Video Lecture | Create stunning 3D Graphics with Cinema 4D - 3D & Animation

hey everyone it's EJ from I design calm
and the past like month or so I've been
able to mess around and play with in
beta test cinema 4d r14 and since
everyone just got the beta of just last
week during sea graph I figured I'd be
able to start doing tutorials and show
you guys how to actually use it and talk
about it when you guys can actually know
what the heck I'm talking about and play
with it yourself so I'm sure you've
heard all about you know sculpting seems
to be the big thing everyone's talking
about and really I don't sculpt I'm a
motion graphics student I don't do any
modeling or anything like that so I
wasn't so enthused about that but if you
follow me on Twitter you'll you'll know
that one of the things that I've really
been having fun which is aerodynamics
the new dynamics function that they
added and I noticed this was missing you
know I was working on my one tutorial
the springs and spline dynamics the with
floating balloons and I did this render
and I I played with the turbulence and
wind settings and all the things in
dynamics that you can possibly play with
and this is the result that I got so all
that work and it's not looking good at
all this balloon back here come on this
balloon back here is just standing
straight up it's not getting blown
around knocked around by the wind or
turbulence or anything so I found out
they're adding aerodynamics to r14 I was
like alright well let's go back to this
project and turn on the aerodynamic
settings and see if it actually you know
the balloon actually gets blown around
by the wind like it would naturally and
it actually did so I'm going to show you
how I got that look and show you a
little bit about aerodynamics and r14 so
got my balloon in the scene I added a
wind object down here it's pointing up
so the wind is blowing upwards because
we want our
learn to go up right so we've got our
turbulence here as well and right now
the you know dynamics winds on so we're
actually going to just do it back to its
default settings for now I'm going to
show you what it would normally look
like without aerodynamics so first
things first let's go to our balloon and
let's get our rigid body tag force you
can see that we have aerodynamic
settings here already but we're not
going to we're not going to mess with
that right now so this is with like wind
non aerodynamic wind and turbulence so
let's bring these values up zoom out
here and hit play so it's looking pretty
much the same let's actually bring the
wind down so we can see what's going on
this is what that's a little bit too low
we're get back here okay so this is how
its was looking in the video that I just
showed it looks lame and doesn't react
with the wind so I'm going to show you
I'm going to turn on the arrow
aerodynamic settings in the turbulence
go under mode there's aerodynamics win
that's what you want and we're going to
turn it on here as well
turbulence settings yeah we want the
scale up don'twant will sleeve up the
strength for now so you can really
really see the turbulence gone so along
with those aerodynamic settings turned
on on the actual particle modifiers here
you need to turn on the aerodynamic
settings here the lift and the drag so
what the lift does is actually if I
bring this up the lift is actually the
lifting force so the lift is lifting the
balloon up and how that's working is
it's actually recognizing all the
polygons and pushing up against
and right now it's not doing - not a
whole lot right there what let's make
sure oh because the turbulence down
let's do 150 there we go so now alright
so we've got the lift going see that
just need the turbulence so you get
really get the turbulence going it's
balloons don't do that so we're not
quite there yet so along with the lift
is a drag setting and the drag setting
is basically like like for the friction
force of the air so if you bring this
out I always found that for release this
balloon you want the drag to be a little
bit less than the lift so it kind of
helps stabilize it adds a little bit of
friction so it keeps that balloon
upright so it doesn't kind of hang down
like it did I mean it still has a
tendency to do that but it's looking a
little bit better the last thing I
figured out to get this looking right
one thing that's cool when our 14 is see
this reflection I have a reflection in
the environment channel that I'll
actually show up in your viewport now I
don't think that was I don't think that
was existent before so if you have like
an HDR eye or something you actually see
your reflection on your objects or at
least a really low res version so you
can kind of get a handle of where
they're showing up also works with
shadows as well so just a little cool
little nugget there's a lot of really
cool UI enhancements in our 14 like when
these little icons light up when you
hover over them so cool stuff that I'm
sure you guys are finding out already
but so where were we
okay so the last thing that you need to
understand is when you're working with
these objects is that they're not going
to you're there's going to be a lot of
tweaking I had to get these turbulence
settings and the lift settings the right
way and there's also like the air does
enter density settings that you have to
mess with too but basically the air
density setting is a multiplier for the
lift and the drag settings so by hit f5
you're going to see those
the Aaron lift really be more pronounced
so it's really really interacting with
you know lifts really pushing it pretty
good in the drags working a little bit
harder as well so you have a little bit
more interaction with the turbulence and
the wind there so let's turn that back
down okay so the last thing you have to
be aware of is since it's working with
your polygons and the shape of your
object you have to be mindful of where
the actual center of gravity is on your
object so with a balloon you know it has
a specific center of gravity because of
like the air in it and it's it's not
quite rotating right now how it would
it's still kind of like going up here
it's kind of tilted to the side to it
slowly starts sagging on the left a
little bit and why that is because the
center the center of gravity is off off
a little bit what you end up having to
do is have to choose a custom center
because when you throw a rigidbody tag
the center of mass is automatically
calculated and that's not always right
especially when you have odd shaped
objects like a balloon so what I had to
end up doing was playing with the custom
center and the custom center on the
y-axis here this middle one because the
you know you want to have the center
axis like in the middle here so how I
measured that is actually if I get a
null and I let's go into my side MIT
whoop my side mood here and drag that to
the bottom and I bring this to the top
you I found the sweet spot is somewhere
and from like 220 to 230 and that's what
actually worked the best with me and
it's a trial and error like all the all
these settings for me to get this look
right you're gonna have to mess around
with a lot of that air in the drag
settings the air density settings the
lift settings to get the exact look that
you want so but I found that the sweet
spot for
the custom ass Center was 325 so now if
I back out here a little bit and hit now
you're really seeing the turbulence
acting on that balloon a little bit more
realistically it's kind of rotating
being jostled around as a normal balloon
would that's kind of hard to follow this
guy come on zoom out a little bit so
there you go it's still tilting a little
bit but you can really see that it's
interacting with that turbulence much
better and kind of just being jostled
around the way it should and you can
really get a sense of changing the
center that your custom center of
gravity by putting in like really crazy
values let me go back here so let's do
let's do 800 and so the the center of
the custom Center is going to be like up
here somewhere which is completely wrong
but you're going to see how that works
is like so that's what you're looking
for that's locally you want go for it
but that's looking kind of weird so you
can really see how important that the
center the custom center is with that
works with aerodynamics because it can
be completely off and on the flip side
let's do like a negative number so the
center of mass is like down here so it's
going to be flipped around this center
of mass hit play and whoo
we zoom out so that's not right either
so a lot of a lot of trial and error to
try to get the right custom center
they're gone let's actually let's say we
want to follow this guy all the way up
I'm going to show another cool setting
to cinema 4d r14 is the camera morph tag
and so let's say if I want a camera to
follow this guy all the way up and I
want to be able to control the movement
the whole entire time what I can do is
set up two cameras and let's go to the
view of the first camera here and get
the look we want you can actually mess
with the focal length and stuff here up
do it - like this - 28
zoom in here and let's hit play because
I'm going to move the second camera to
be in a view of the balloon at frame
let's just stop it like 150 so let's go
up to find so we're in camera 1 view
which is actually camera 2 I just need
to rename them so there's there's the
balloon let's rename these so we don't
get confused
so let's camera one that's camera 2 so I
have the view of camera 1 here and if we
go back to 0 and hit the view of camera
1 another cool feature is it actually
will interpolate between the cameras so
you can get let you get a little better
sense of where your cameras are on the
scene because it won't just snap into
the second view it'll actually just kind
of dolly to the second camera view so
alright so we've got camera 1 and if I
hit play
go away 150 if I hit the view a camera 2
that should be in view of that so I'm
just using the 1 2 and 3 keys to change
the rotation so that's that's looking
good so now to set up our morph camera I
actually need a camera a third camera to
add the camera morph to the camera morph
tag - and you'll see we have simple
morph with just one camera morph into a
second camera
we have multi morph which you can put in
all numerous kinds of cameras you can
add as many cameras as your heart's
content so right now we actually just
need two more from camera one two camera
two so I'm going to put camera one and
camera one and camera two two camera two
and if I start at the beginning again
and I move the blend you'll start to see
this is better to see and like a side
view here wrong side whoop there we go
so we got our two cameras and when I
bring a blend percentage up you'll see
this the morph camera interpolating
between those two camera views so it's
really it's extremely easier to do
camera moves camera animation in your in
your compositions now so what I'm going
to do is you know it's at zero so it's
at camera one view I'm going to hit the
keyframe and I'm going to go all the way
to frame 150 bring the blend all the way
to 100% so that'll be a hundred percent
in the camera to view and I'm going to
go back to the frame zero hit play
right now I'm interpolating between
camera one and camera two as views so
get to follow this balloon all the way
up so we can see how this thing's
looking so pretty cool pretty cool
features to our 14 and as far as
dynamics go and there's a lot more
additions that they added to dynamics as
well such as like plastic and breaking
Springs with connectors and stuff like
that and this also works pretty well
with soft bodies but uh this is just you
know how could work with a balloon or
something non airplane II so have fun
with the beta and if you would like to
see what where other stuff you guys can
do I'm going to actually post this file
so you can have my fun balloon scene and
you guys can play around with getting
your balloon to
look messing around with the wind look
pretty realistic as well so I'm gonna be
doing some more tutorials on some r14
stuff if there's anything in particular
you want to know more about want to see
in action a little bit more just let me
know in the comment section and have fun
with the beta guys see it
