All language subtitles for 4. Adding Lights and the Dark Side of the Planet

So now that we have our clouds in there,

let's go in here and see how we can get this nice,

dramatic lighting change to happen,

and let's take a look at adding the lights on the dark side of the planet.

So the first thing I'll do here is zoom in in the Node Graph,

and I'm going to right-click to bring up the 3D menu,

and go to the Lights option, and I'm going to pick a Point Light,

and drop a Point Light in the scene.

I'm going to connect that up to our Scene Node,

and let's take a look at why that Viewer disappeared.

We have Viewer1 that's connected to the ScanlineRenderer,

so that Viewer disappeared because, let's jump over to 3D space,

it's now calculating light in the scene,

and that light is buried in the center of our planet.

So, that makes perfect sense.

I'm just going to pull this light out a little,

and I'm going to switch our second Viewer over to the

scanline so we can see what's happening,

and you'll see now we have a planet that's beginning to be lit here.

So if I look at the attributes of this light,

I can just change the intensity,

or I can go in here and I can move this light around,

and it's going to affect the lighting of the scene.

Now I took some time before this clip to go ahead and find

the right values for this Point Light,

so I'm going to go ahead and just type these in now.

In the translate, I want you to go ahead in here and put 12.

85, in the Y I want you to put 5.

739 into that parameter, and then in the Z, 12.

680, and hit Enter,

and for the intensity I want you crank that thing all the way up to 100,

and I want you to change the falloff type to linear.

And now we get a nice look that kind of matches our previous render,

and you know what, let's go ahead and move that up in Y just a little,

just want to get that curve looking more like the image on the left,

and we can kind of eye that up, so that looks a little better,

so that value's 9.

539.

And now I'm going to ask you to do something a little weird here,

so follow along with me.

I'm just going to take this entire comp over here that we've done so far,

and I'm going to hit Ctrl+C,

I'm going to hit Ctrl+V just to duplicate it so that we have an exact

duplicate of the comp that we were working with before.

And we need to make sure that we're looking at the right comp,

because now you see because of the duplicate we have a Viewer3 in here,

and that's not represented by either of these windows.

So things can get kind of crazy kind of fast.

I'm just going to delete that out and I'm going to make

sure we're looking at the right comp,

so I'm going to take this Viewer2 and connect it up over here,

and now this window is corresponding to the copied comp that we made over here.

Now just to confuse things a little more,

I'm going to come over here, and I'm going to disconnect this Viewer,

I'm going to bring this Viewer over to our copied comp,

and I'm going to view the 3D space of our copied comp over here on the left.

And you notice that we have the Point Light 1,

this is our Point Light over here in the original comp,

so be very careful that you're working with the right Point Light,

and I'm going to double-click on Point Light 2,

and I'm just going to move this light up a little and over a little.

And you'll see the light is being affected on the left,

and all we're doing is giving ourselves a little extra ridge of light in there,

and I want to change this intensity to 250.

Now I want you to go up here,

and I want you to grab the image of the red lights that we brought in earlier,

and just drag it over, and into our copied comp,

we're going to be replacing this image of earth with the lights,

and you can go ahead and you can disconnect out the clouds.

We won't need the clouds, and I'm just going to delete these,

and this is essentially going to become our lighting

pass on the dark side of the planet.

Now, since we're only working with red data here,

I'm going to drop a shuffle in here,

and I'm going to copy that red channel over into the other channels.

Just like that, and that's going to make it white,

and that's also going to give us an alpha,

if you hit A on the keyboard, that looks just like our colors,

and then I'm going to take that and plug that into the sphere,

and we will check to make sure that is lit.

I'm going to turn the Point Light on and off,

so that looks like our lighting is working to kind of blend this out,

and now let's combine it with the other image of earth.

So I'm going to go back to my original comp here,

and I'm going to connect up our Viewers to this original comp,

I told you this would get a little confusing.

I'm going to disconnect these, I'm going to bring my Viewer over here.

I'm actually going to pull this out for a minute,

and I am going to hit Shift bracket in this window to get my

menus back to switch this back over to 2D,

and then I'm going to put it back in the window,

it's kind of a little workaround.

And then I'm going to draw a Roto Node.

So I'm going to hit Tab, pick Roto, drop it down here with the Roto selected,

I'm going to go into this window,

I'm going to just kind of draw a rough Roto around earth.

If you select this point and hit Z on the keyboard a couple times,

it should smooth up that curve for you.

I think I'm going to delete this by selecting it and hitting Delete,

and then move that in line with the shadows,

more or less.

This doesn't have to be perfect, we're going to kind of blend it later,

but I just want a rough Roto shape for the moment,

and then I'm just going to drop a Merge Node down here,

and I'm going to, disconnect that,

I'm going to lay the ScanlineRenderer of the lights on

top of the ScanlineRenderer of earth,

and I'm going to hit one on the keyboard to look at that.

Let's close these down, and the lights are now laid on top of the earth,

and let's go back into the 3D view of our scene,

and take a look at that light that we had,

and let's just go ahead and move that light over just a little more,

and we'll see we get a little more of the lights in the shadows,

which is kind of cool.

And now let's bring our Roto over and connect it to our Merge,

double-click in the Merge and say invert,

so we're inverting the Roto shape,

and you'll see if we select all of these lines,

let's get really big and close on this,

we can move where we want the lights to appear on the earth.

So if we go back to that Roto shape,

I'm just hitting Space on the keyboard to jump between those things,

I can select the curve of the Roto and I can feather it,

which means that we're just going to blend it a little,

and you can blend it any way you wish.

So I'm going to look at the whole thing,

I'm just going to probably blend it like that so we just see a little

bit of the lights on the side to give us the feeling that there's

something there on the dark side of the planet.
