WEBVTT 00:00.710 --> 00:01.850 Welcome to the mix. 00:01.850 --> 00:07.130 RG been showed in this video will use it to mix two colours together. 00:07.490 --> 00:14.930 Will see that it can also be used to mix more than just colours except six channels in through the two 00:14.930 --> 00:21.890 colour inputs and three channels out mixing together those two colour inputs based upon two things. 00:21.890 --> 00:29.830 The blend type and the factor says Go play with this mix r.g. be note now and hop on over into blender. 00:31.880 --> 00:37.290 Okay so I'm going to be working on a sphere because I'd like spheres. 00:37.310 --> 00:38.230 Simple as that. 00:38.340 --> 00:41.950 So let's go ahead and add a basic sphere to my scene. 00:41.960 --> 00:47.660 I'm going to lift that up and I'm also going to add a plane to the scene and scale it outwards. 00:47.690 --> 00:53.350 Now just to make sure my materials from last time are working I'm going to make a chequered floor and 00:53.380 --> 00:55.450 this is going to be that. 00:55.460 --> 00:55.870 Ready. 00:55.880 --> 00:56.510 Plastic. 00:56.510 --> 00:58.620 Let's switch into rent mode. 00:58.700 --> 01:05.450 Perfect Couple of things left to do here is this particular sphere needs to be so nice and smooth so 01:05.450 --> 01:06.960 we can see what's going on. 01:07.280 --> 01:12.230 Excellent so that's all set up and ready to go see the power of having all of these materials set up 01:12.560 --> 01:16.030 ready to go just makes things setting up so much quicker. 01:16.370 --> 01:18.980 So let's grab a node editor. 01:19.000 --> 01:25.520 I'm going to just get rid of some of the toolbars around here and the node editor open here. 01:25.670 --> 01:32.990 Now one thing we can do here is change the colour so oh notice this is polished wood here I've obviously 01:32.990 --> 01:40.340 used this basic for an L node that we had set up before the scroop node used on something else and forgot 01:40.340 --> 01:45.590 to click the little number over the property to make it unique some chemical that P. 01:45.620 --> 01:51.950 B r and I made a note to go ahead and make sure I save that to my the fault file again so I don't have 01:51.950 --> 01:53.370 to do that multiple times. 01:53.390 --> 01:55.040 So we've got a colour input here. 01:55.050 --> 02:02.720 Now what we can do in this colour input is have a mix of two separate colours coming in for instance. 02:02.720 --> 02:08.600 So you could go ahead and add in a colour under the add colour menu mix. 02:08.600 --> 02:13.480 RG So you've got a colour output that we can put straight into here. 02:13.730 --> 02:19.680 Now we've got two colours now I'm going to choose almost 100 percent green. 02:19.780 --> 02:25.190 I know we shouldn't choose 100 percent colours but again we're just testing the mixing that's going 02:25.190 --> 02:32.180 on here and 100 percent red and non-support or not surprising at all we get a yellow out with a 50 50 02:32.180 --> 02:33.050 mix. 02:33.050 --> 02:38.410 Now we've got a couple of options here we can change how all these are mixed together. 02:38.450 --> 02:44.660 If we want to and you can go through and try the different varieties of mixing that we can go through 02:44.960 --> 02:51.410 I tend to leave it's just on mix in general and we have a factor here that obviously we can change it 02:51.410 --> 02:52.920 from one to the other. 02:53.120 --> 02:54.720 But of course that's boring. 02:54.720 --> 02:59.320 We'd want something to control this factor itself. 02:59.630 --> 03:02.410 And that leads me nicely onto a challenge. 03:02.570 --> 03:07.070 I'd like to go ahead and get mixing so use the mix. 03:07.070 --> 03:14.870 RG been known to mix together to colours control the factor with the generated texture. 03:15.080 --> 03:21.890 And then for a bit more interest why don't you try adding a bump node into the system using the texture 03:22.160 --> 03:28.490 to add more interest in the material and affect the normal so it's not just a smooth surface anymore. 03:28.760 --> 03:31.490 Pause the video now and give that ago. 03:33.690 --> 03:35.250 Okay guys welcome back. 03:35.250 --> 03:37.680 Let's go mixing over in blender. 03:37.860 --> 03:43.860 Okay so we're back over in blender and we've got this mix note here and it's a bit boring at the moment 03:43.860 --> 03:46.330 with just these two colours. 03:46.410 --> 03:48.660 Now I've got an idea I'd like to try. 03:48.840 --> 03:53.590 I'd like to try adjusting this factor using a texture. 03:53.800 --> 03:55.800 So let's go ahead and go to textures. 03:55.800 --> 03:58.470 And of course if you got an image texture you could apply. 03:58.500 --> 04:00.080 You could go ahead and do that. 04:00.090 --> 04:04.610 But in this case I'm going to use one of these generated textures wave. 04:04.640 --> 04:08.020 I to add that to our model. 04:08.400 --> 04:09.770 I've added it to the wrong part. 04:09.770 --> 04:10.200 There we go. 04:10.200 --> 04:16.520 So in fact and let's just have a look at what the wave is outputting on the colour and on the factor 04:16.780 --> 04:20.130 whereas putting the same thing on both in this case. 04:20.130 --> 04:27.550 So here we have a black and white texture so it's alternating between green and red. 04:27.570 --> 04:30.860 So let's go back to our Mc snoad and see what the outside of there is. 04:30.900 --> 04:31.420 Okay. 04:31.430 --> 04:33.090 And everything together. 04:33.270 --> 04:34.800 Okay that's starting to come together. 04:34.800 --> 04:38.100 Now I'm going to play with the scale settings here. 04:38.630 --> 04:43.680 And I want to increase the distortions a bit wavy Yeah. 04:44.000 --> 04:44.830 Okay. 04:45.080 --> 04:49.710 That's a lot of distortion there that's lower the scale even more if I can. 04:50.150 --> 04:54.840 And this detail I'm going up the detail so we get a kind of a mottled affect. 04:55.030 --> 05:01.370 So so go take a little bit of playing to get the kind of effect that I want some not quite there at 05:01.370 --> 05:03.830 the moment 50. 05:03.880 --> 05:05.860 Let's try a hundred and fifty. 05:06.020 --> 05:09.640 How that's starting to look better. 05:09.950 --> 05:10.740 Excellent. 05:10.740 --> 05:17.060 So we changed these colours here servair a bit more representative of what this sort of colours that 05:17.060 --> 05:17.620 I want to. 05:17.630 --> 05:23.140 Again I'm going to try and avoid using extreme to extreme colours. 05:23.150 --> 05:25.230 I want them to be semi realistic. 05:25.250 --> 05:31.670 Okay so we've got almost like a cloud covered marble or something on those lines. 05:31.670 --> 05:38.660 Now to add a little more interest into this I could actually use this wave texture that we've got here 05:38.690 --> 05:39.590 because it's black and white. 05:39.590 --> 05:46.610 We can use it to control something else now flat things like this are boring so we can add some real 05:46.610 --> 05:48.230 texture some real bumps to it. 05:48.230 --> 05:55.490 By utilizing this wave texture as well to control a bump node so if I go ahead and add in a bump node 05:56.040 --> 06:01.790 to remember where it is and a vector bump and we can use it to control the height some would become 06:01.910 --> 06:07.310 to use the factor in this case to control the heights and then are going to have a look and isolate 06:07.310 --> 06:08.890 the bump mode and see what's happening. 06:08.900 --> 06:14.460 Now we will see the normal output but we can see there's quite a cool texture being applied there and 06:14.480 --> 06:20.750 we can adjust the strength of that accordingly and leave it set to one and distance here is obviously 06:20.750 --> 06:23.390 going to make kids more or less extreme. 06:23.390 --> 06:29.890 And I'm going to leave that's quite low down so we don't o'farrelly exaggerates what's going on. 06:29.900 --> 06:33.430 Okay so these together let's have a look at what it looks like. 06:33.460 --> 06:39.950 I need to plug the normal in to the normal input we've got set up a How about that they're starting 06:39.950 --> 06:43.040 to look much more interesting with all the textures. 06:43.040 --> 06:48.730 Now we've got something we can look at and I can see the we can still see some facets around here because 06:48.740 --> 06:54.500 we've not applied a subsurface division modifier to it to smooth it out for shading. 06:54.500 --> 06:59.600 Now we can go in and tweak these settings to see little of all those almost like rivers running through 06:59.660 --> 07:01.130 a valley. 07:01.230 --> 07:04.670 We could use a colour ramp know to make things even more interesting here. 07:04.670 --> 07:07.170 Now I'm going to go diving into details there. 07:07.240 --> 07:12.680 I really like that looks like some sort of rocky marble Let's turn the scale down tweak it a little 07:12.680 --> 07:12.990 more. 07:13.000 --> 07:14.070 Okay. 07:15.210 --> 07:20.830 There's lots and lots of fun you can have just tweaking settings left right centre. 07:21.060 --> 07:23.740 Just see what you can come up with. 07:23.850 --> 07:27.480 And of course I have not got time to play with it all. 07:27.570 --> 07:28.000 All. 07:28.020 --> 07:28.750 I like that. 07:28.750 --> 07:31.360 Another time to play with it all day long. 07:31.480 --> 07:33.320 But I'll leave you guys to do that. 07:33.360 --> 07:38.890 Please share your work in the discussions and I will see you guys in the next lecture.
