- [Instructor] Here, we'll take a look at more sophisticated…techniques for creating interactive lighting effects.…First, we'll get tricky to create a…difficult procedural mask.…Then, we'll use some Nuke automation to procedurally animate…a lighting effect to a flickering campfire.…Now, this scene has some obvious strong lighting…from the right, but our character, not so much.…So we'll come down here and add…a strong lighting effect to the right.…Now, in this case, the challenge is creating a proper mask…because we need a mask that will be thick,…right here in the mid part,…but much narrower up here in the hat.…
So we need a technique that will adapt…to the width of the character.…So let's take a look at what got here.…Let's come up here and take a look at our alpha channel.…We'll scoot in.…First thing I did was invert it.…And then, I used a Grade node to knock it down.…The reason I wanted to knock it down is…because I'm going to add together…a whole bunch of copies of this thing,…and they're gonna get brighter, brighter, and brighter.…
