we're gonna be making medically illustrated stem cell looking thingies

and if you go any type in stem cells you see like a ton of images that look very

similar to this so I'm just gonna say that this is probably the agreed-upon

way to illustrate stem cells out in the world if you're not looking at it under

an electron microscope got it let's get started the first thing I'm

gonna do is I'm going to use a default cube I'm gonna select him and I'm gonna

hit control v on the keyboard now why the heck would I do that here's why if I

go over to the modifiers tab over here that just added in a subdivision surface

so I didn't have to go look ahead modifier and buy subdivision surface and

then set out so I was just able to do it control v normally I would never hit

control v because that would choke most computers but being that we started with

a cube low resolution we just get this so now what I'll do is viewport is set

at 5 render I'm going to set at 5 so that way when I hit render later I don't

have an oops look at that it looks like crap it's gonna look like pretty much

what I want it to look like ok you'll see later

now second thing I'll do is I'll create the nucleus so to do that I'm just gonna

go to add modifier I'm going to say displace and it makes it huge not what I

want I'm gonna hit new it makes it small again not what I want

Thank You blender so what I'll do is I'll hit this little thingy over here

show texture tab intro texture and texture tab which is the same as hitting

this so I'm not sure why these are both here but hey that's cool whatever so I'm

gonna hit that and I'm gonna say type not image or movie and I'm gonna say

Voronoi and boom hey look at that that's kind of cool

and then distance metric I'm gonna change this to distance squared there's

no real reason I'm doing this other than the fact that I just kind of like the

way it looks so I'm gonna take this I'm gonna say object I'm gonna say shade

smooth and then I'm gonna go back to my little wrench here for modifiers I'm

going to turn the strength down I'm gonna go negative like point 3 and look

at that I now get this cool like blobby look and that's just what I would

imagine the Selden stem cell nucleus would look like because I fiber saw one

here life which I haven't and you probably

haven't either what's your a scientist so what I'm gonna do now is I'm gonna

make the membrane to do that I think I'm gonna add a you know I'm gonna just

duplicate this cuz why not I like I have it like why not duplicate it right

though shift D duplicate it so click once so it's not tied to this move tool

and then you're gonna hit s on the keyboard and scale it up just a little

bit and with this I can kind of just take down the strength of this and I can

also go ahead and instead of using Voronoi here I can use light let's see

noise I don't like that Stu sheets to choose let's say stuccis doosh doosh

doosh e stucci sounds good maybe purlins improve purlins sure

that's fine that'll probably work for what we need right now so now let's go

ahead and begin to shade this thing so the first thing I'll do is I'm gonna

turn on evey so I'm gonna go over here to rendered up

this little thing I'm gonna go to my little back of the camera thingy or

whatever render and I'm going to say screen space reflections I'm gonna go in

here I'm gonna turn off half rest trace and I'm gonna turn on refraction yeah I

like that yeah that'll work men shadows I think I'll turn on high

bit and soft shadows cuz why not I'm I'm in here I'll use it that's fine and

that's probably good enough I think I have everything set the way I want it so

I'm happy yes happy so what I'll do now is I will use the shading so I could go

here and use the shading tab but I think I just want to use this so I'm just

gonna go down pull up a little window here and I'm going to say shader editor

so now I have a shader editor and we can see everything and it looks great and

blah blah so what I'll do is I'm gonna say my original cube which is the one

inside here I'm gonna rename to nucleus it's not new coulis

nucular its nucleus and then I'm gonna change cube ah double click and say

membrane insane whatever so check that out or cool I like that now oh okay so

membrane I have this material I'm gonna go ahead and I'm gonna say transmission

all the way up and you see absolutely nothing happening in here the reason for

that that we don't see through this is because they don't give us this by

default so we have to go down here to material alright for membrane material

we can go scroll all the way down and blend mode I'll say alpha clip turn on

screen space refraction okay so we'll play with refraction depth and we're not

gonna really touch that yet what we need to do also is realize that nucleus and

membrane-bound the same material so let's go to nucleus here let's go to the

materials tab scroll up and we're gonna add a new material to nucleus and so I'm

going to go ahead and I'm going to name this one membrane and this one I'm gonna

hit new I'm going to call this nucleus shader or whatever and I'm gonna hit tab

with nucleus and then I'm just gonna hit a sign so yeah I have nucleus on a sign

and hit tab again and now I have the nucleus inside there so for nucleus here

I can go ahead base color change it to whatever I want like red it's fine and I

could turn the roughness down make it shiny leave that as is and what I could

do here on membrane now is I could turn the roughness down and you see we're

seeing through it well that's kind of nice and what if see how it's like

really refracted if I don't want it to be super refracted I can take the

refraction depth and kind of play with that

and you can I mean you can get really really accurate here but if you're doing

just like kind of artistic looking stuff you can just kind of leave it as is and

find something that you're kind of happy with and then I'm pretty okay with for

now so roughness here you can turn that up and give it more of like a rough kind

of membrane but you get the you get the picture

next what I'll do is I'm going to play with the world so I'm gonna go over here

to object I don't change this to world and if I scroll with my mouse and I pull

out here I could see I have a background background here change it to black

nothing change it to white see everything so you can play with this or

you can do something really interesting with this and go add or hit shift a

either one go to texture I'll say Voronoi I'll color to color and there I

have kind of a cell looking shader and again you could put anything in the

background here HDRI anything anything you want but I'm just gonna do this for

the sake of this video and then I'll make it a kind of a bluish color maybe

so I'll go shift a get a converter color ramp take Voronoi out here factor to

factor color to color and now I can go ahead and change this to whatever color

I want so I'll go like a kind of light blue I don't know something like that

and you can play with the scale and just kind of get something that looks

somewhat interesting to you and you can also take another Voronoi shifty take

the factor plug that into like scale and start getting really kind of broken up

looking stuff so there's a million things you can do here there's no one

way to make anything look cool I'm just doing this for the sake of the video to

throw a background in here and start getting some refraction and reflection

in this object okay so next let's play with the camera will

so I'm just gonna take the camera and position it so I'm gonna select a camera

and I'm gonna hit alt R and alt G that centers it and clears out the rotation

now what I could do is select this little arrow up here and I'll go to

rotation on the X I'll hit 90 that's just gonna face it right down that way

go to the move tool pull it back a little bit and now I could hit 0 and

there we go so we're starting to get something that's passable as a as a you

know decent composition so now we can work on the lighting so notice I did not

turn on lock camera to view if you do that you can kind of scroll around and

move the camera around but I'm gonna leave that off for now and I'm just

gonna work on lighting so quick quick and dirty lighting here simply gonna add

and empty into the center and then I'm gonna add in a light and I'm gonna say

area light and I'll pull back pull that area light up and then I think what I'll

do is I will I'm gonna make that stare at the center so what I'll do with that

is go to constraint hit track to Target choose my empty and then for this one

I'll use negative Z and I'll just leave it at that it's not active right now

because it's not working but we're gonna we're gonna change that in a minute

so I'm gonna hit shift D now to duplicate this guy and pull them around

and you'll notice that he still has the constraint on it so now all I have to do

is just kind of find find his happy place which is on the Y so you leave

that there just hit up Y and there you go so now I have this guy staring

straight at this as well and then I can duplicate him shift D okay pull him over

and he's looking that way too so now I have kind of a three-point lighting

setup where I can just find whatever looks cool to me

and go with it so what I can do now is hit zero again and start playing with

the lights so area light one is above us

I don't even need this on anymore but I'll just leave it for the for the sake

of it why not it's not hurting anything and I'll say power 150 and I could take

the size here maybe go 25 it's pretty big and 1,500 I start getting something

something workable 15000 I start getting something really crazy and I could see

that this thing is a kind of flickering so to fix that this is really quick fix

not sure this is like a really great solution or not

but you could take viewport here sampling so if you go here to render and

just turn that down to zero and that just kind of takes that flick or I'll

for now so we're not looking at anything it's crazy so now I get to take these

area lights here and I can play around a little bit more so I can click on the

light so a hit area click on the light and I can give it more so let's say 150

from the side 1500 from the side blow that up to like 8 1,500 other side blow

that up to 18 and then you can move these around and kind of find something

that you're happy with and these work is lights in the real world so the further

you pull them away the less intense they get and they pull them up on the wall on

a Z pull them back a little bit more and you start getting start getting lights

and a look that you can kind of dig you can go back and play with these it as

well so let's see if I go to world and I go to object here

okay roughness it's up a bit you can see you pull it out pull it in and start

getting something that looks kind of selfish and now we can also do is I can

back out of here so what I'll do is I'll go to get a view lock camera view scroll

out a little bit and I can make this guy membrane hit s make them a little bit

bigger and now I'm starting to get this shape

so I can also go to membrane here or nucleus and what I'll do is I'll turn on

some subsurface scattering and my base color here I kind of push up something

interesting and the membrane here also really play with the strength and I can

also go back to texture here play with the size a little bit make it more

membrane II go back here strength like negative one and you start getting

something something usable no we could also do here is take our area lights

kind of pull them out and get something that kind of works

now it'll do is I can duplicate the heck out of this thing so I'm going to take

off look lock camera to view and I'm gonna hit B on the keyboard and select

both of these I'm just I don't want area selected I just want my nucleus and my

membrane selected okay hit shift D pull that out you can scale this guy down a

little bit okay shift D pull him out shifty shifty shifty shifty and you

start getting something kind of interesting lastly here I can add

another light all the way in the back so I can go add light throw a point light

in there turn it way up and push it all the way back maybe take another one here

and pull them into the front

and see what we get all right we're getting more light now looking a little

bit better getting nice reflections off the other

lights they're starting to reflect each other and I can keep going with this and

massaging it it's almost something I'm really happy with but the video will go

on and on and on and on and on forever so at some point we have to keep going

so what I'm gonna do here is get camera and I'm gonna just throw in depth of

field now so I'm gonna say camera I'm gonna add another empty in here this

time maybe a cone so I can see it it has scale it up just like it see it it's not

a not a rendering object so don't worry about it and then I'm gonna camera I'm

gonna say depth of field focus on it be empty

0:01 look at it name did cone whatever doesn't matter and I'm going to say
