00:00:06,030 --> 00:00:12,240

All right now let's take a look at one more kind of map that we use to add even more or better details



2

00:00:12,240 --> 00:00:14,340

to our object over here.



3

00:00:14,610 --> 00:00:22,280

And that would be the specular map and now specular maps act kind of in the same way as a bump map.



4

00:00:22,290 --> 00:00:29,310

But whereas a map is for the bump and the look and the texture and the geometry of the mesh a specular



5

00:00:29,310 --> 00:00:33,710

map is just as it implies it manipulates the Specularia of it.



6

00:00:34,050 --> 00:00:37,890

So you can see right here that we have secularity or shiny ness.



7

00:00:38,040 --> 00:00:40,510

Pretty much all over the floor.



8

00:00:40,650 --> 00:00:43,850

Right now it's determined by this factor over here.



9

00:00:44,010 --> 00:00:46,380

So 50 it's at point five.



10

00:00:46,380 --> 00:00:57,680

So at 0 it's actually fully diffused and out one it's fully specular or fully glossy now at point five.



11

00:00:57,670 --> 00:01:04,890

It's just distributing it half and half and that's not the most realistic thing because it's kind just



12

00:01:05,640 --> 00:01:10,080

you know it's an easy way to do it but there's much better way to do it and that's using a specular



13

00:01:10,080 --> 00:01:17,390

map which just like the bump map will dictate where it's shiny and where it is diffused.



14

00:01:17,430 --> 00:01:20,420

So where it's diffuse and where it will be glossy.



15

00:01:20,450 --> 00:01:25,740

So in order to add a specular map all we have to do is going back to Photoshop.



16

00:01:25,740 --> 00:01:33,810

Let's go back to our image and now anything that is White will be specular or will be glossy or shiny



17

00:01:34,290 --> 00:01:39,100

and anything that is black will have no shine or no glossy ness to it.



18

00:01:39,550 --> 00:01:52,720

So let's go ahead and go to image adjustments brightness contrast let's bump up the contrast of Llobet.



19

00:01:52,840 --> 00:01:54,430

I don't know what just happened there.



20

00:01:55,320 --> 00:02:01,140

And the brightness I want to bring it down Also I don't want too much shine to my wooden floor everywhere



21

00:02:01,170 --> 00:02:07,560

you know I only want in a couple of places so I kind of like that feel to it you know where the white



22

00:02:07,560 --> 00:02:12,810

is right here that's where it's going to be shiny or specular and all the rest where it's black and



23

00:02:12,840 --> 00:02:16,320

kind of ish or be less or no secularity at all.



24

00:02:16,410 --> 00:02:20,970

You can see that right here in between the crack that will be no shine at all which is what we want



25

00:02:21,370 --> 00:02:24,210

to see before with just 50 percent.



26

00:02:24,240 --> 00:02:30,900

There might be secularity or shyness in between the cracks which makes no sense at all because that's



27

00:02:30,900 --> 00:02:35,000

where there should be no shininess because there's nothing to reflect against.



28

00:02:35,250 --> 00:02:41,640

So this way it actually we're able to dictate where the shininess and non-changing is.



29

00:02:41,640 --> 00:02:43,590

This is going to be pretty awesome.



30

00:02:43,750 --> 00:02:44,420

Let's go ahead.



31

00:02:44,450 --> 00:02:45,180

OK.



32

00:02:45,600 --> 00:02:47,580

File Save ads.



33

00:02:47,790 --> 00:02:55,440

Let's save this as wood floor spec for speculated secularity.



34

00:02:55,890 --> 00:02:58,360

Save that and hit OK.



35

00:02:58,530 --> 00:03:00,210

Going back into blender.



36

00:03:00,630 --> 00:03:06,390

Let's go ahead and all we have to do and one more thing we want to do on our image texture here since



37

00:03:06,390 --> 00:03:08,990

this is a black and white image texture map.



38

00:03:09,000 --> 00:03:13,680

Let's change it from color right here to non-color data.



39

00:03:14,160 --> 00:03:19,470

And now we'll just make sure that's only using black and white values and there's no color values although



40

00:03:19,470 --> 00:03:22,980

there shouldn't be but it's always good to check that.



41

00:03:23,040 --> 00:03:28,150

Now selecting this with the right mouse button shifty to copy to copy it.



42

00:03:28,470 --> 00:03:29,900

Let's bring it over here.



43

00:03:30,300 --> 00:03:38,700

And now what we're going to do is delete or hit the X to remove this image open and we're going to go



44

00:03:38,730 --> 00:03:45,320

to our specular map and open that image up.



45

00:03:45,390 --> 00:03:51,660

Now bringing the color input right here by left clicking we're going to bring it down here to the factor



46

00:03:51,660 --> 00:03:54,060

and put on our mics shader.



47

00:03:54,360 --> 00:04:02,110

Now you can see that it basically allows for the it takes this texture into consideration instead of



48

00:04:02,110 --> 00:04:05,670

the factor output that we had here previously.



49

00:04:05,670 --> 00:04:10,510

Now we obviously want to put the gloss units down a little bit as it's still a little too bright.



50

00:04:11,910 --> 00:04:23,320

So I'm going to put it or actually put it up the roughness value I'm going to put it to a point 2 7



51

00:04:23,330 --> 00:04:25,870

5 ish actually a little bit more.



52

00:04:25,880 --> 00:04:28,770

Let him put two point three five.



53

00:04:29,100 --> 00:04:32,310

I don't want too much shyness or glossing this to it.



54

00:04:32,310 --> 00:04:38,310

Also you could play around with the roughness of the diffuse Shater right here and get the look and



55

00:04:38,310 --> 00:04:40,480

feel that you want.



56

00:04:40,590 --> 00:04:42,120

I kind of like it like so.



57

00:04:42,340 --> 00:04:48,250

So now you can see that where our image texture was white.



58

00:04:48,250 --> 00:04:52,450

We have some shining eyes to it as you can see right here it's a little bit reflective.



59

00:04:52,450 --> 00:04:58,540

And again I don't want it to reflective as a wood floor is not going to be you know so I'm going to



60

00:04:58,540 --> 00:05:03,070

have a lot of shine to it but that's basically a specular map.



61

00:05:03,070 --> 00:05:11,350

It's really awesome as very simple to use and to add and gives it just that extra level of detail and



62

00:05:11,350 --> 00:05:12,420

realism.



63

00:05:12,430 --> 00:05:20,010

Now if we select our lamp by lighting here we can actually see if we had to grab it or move it around.



64

00:05:20,500 --> 00:05:28,300

Let's actually switch this light to something like an area light you can see that as we head and move



65

00:05:28,300 --> 00:05:29,960

it around.



66

00:05:30,080 --> 00:05:34,480

You can see the nice details that we have here on our plane.



67

00:05:34,490 --> 00:05:40,750

And again the cool thing is it has all this detail but it's still just a single plane image.



68

00:05:40,760 --> 00:05:43,790

So those are specular and bomp maps.



69

00:05:43,790 --> 00:05:45,700

And this is the node Ed..



70

00:05:45,860 --> 00:05:47,820

Very very useful and very cool.



71

00:05:47,870 --> 00:05:55,730

Let's go ahead and save our project control s save that project and let's take a look at our next tutorial



72

00:05:55,910 --> 00:05:57,170

and what we're going to learn there.



73

00:05:57,260 --> 00:06:02,960

But again feel free to use specular and bought maps on any kind of textures that you want to add more



74

00:06:02,960 --> 00:06:04,120

detail to.



75

00:06:04,250 --> 00:06:07,870

And it's really awesome so I'll see you in the next one.



76

00:06:07,890 --> 00:06:09,930

Ciao.



77

00:06:09,940 --> 00:06:10,290

All right.



78

00:06:10,290 --> 00:06:11,990

Very well done this tutorial.



79

00:06:12,010 --> 00:06:14,440

I'm proud of you.



80

00:06:14,800 --> 00:06:20,980

All right the coopt when you let the love flow from your heart you'll see that we are all connected



81

00:06:21,100 --> 00:06:22,150

never apart.



82

00:06:22,360 --> 00:06:23,600

So just give it a go.



83

00:06:23,630 --> 00:06:25,030

Begin and start.



84

00:06:25,030 --> 00:06:27,520

Let the love flow and do your part.



85

00:06:27,670 --> 00:06:31,060

There's the little poem and love is the universal language.



86

00:06:31,060 --> 00:06:33,490

Let the love flow from your heart and be love.



87

00:06:33,490 --> 00:06:34,690

Ladies and gentlemen.



88

00:06:34,930 --> 00:06:35,570

All right.



89

00:06:35,620 --> 00:06:37,570

Love is a universal language.



90

00:06:37,600 --> 00:06:40,190

See you guys in the next video again.



91

00:06:40,240 --> 00:06:40,940

Take care.



92

00:06:40,960 --> 00:06:43,260

Love yourself love everyone.



93

00:06:43,280 --> 00:06:44,810
