Hey, guys. This is Eric Conan with a quick tutorial on how to do some heat displacement. And you know when something is hot and it is placed in the air around it and to do that I’m going to use these flames here. You can use water clouds or anything you want. And I’m going to use it to displace this heated metal.
Now decided to move to D and to my flames and resize to my hot metal because it was just a small pick and I want to make it larger. So I’m going to lay these flames over top of my heated metal, like so and you can see right here it’s smaller so we want to move to the parameters. And scale it up and have the flames cover the area that we want the displacement to take effect.
So I want to cover a lot of area like that, so I do that. So now we need to go into our work note and add displace so up and add displace but the output coming from the open oven to the second input of displace and put the original resize version or original version of the heated metal or whatever pic you’re using into the first input. So I want you to displacement parameters, scroll down and you’ll see an X and Y channel. Switch your X channel to red, and your Y channel to green. Open up the scale to your displacement and you can up it to about 10, 15 maybe even 18 if you want.
So now we need to create a Roto shape so let’s go to image and create a roto shape. I’m going quickly just copy this resize note and paste it and pop that Roto shape inside it because it needs to be the same size as my heated metal pic just for speed psyche. You can change the size inside the Toto shape itself if you want it. Now I’m going to open the blur, and I’m going to blur it for about 40 pixels. And I want to pop that blur right in to the size of the display, bring up your Roto shape parameters. Let’s look at our hot metal and let’s mask out of place for our displacement.
That looks pretty good, go back to our displays. Let’s frame this up so you can see it better. We might need to make the scale bigger. Let’s go to our displays note up our scale a little bit and play it and you can see here we have some heat displacement coming through those flames. As a matter of fact I can render a small foot book here. It’s actually not small but we should go and tell about it.
So let it get until you’re finishing, that’s 24 frames and I’ll play it back and you’ll see the result and it’s that easy. Of course, you can bring the scale down and adjust your Roto shape and all that good stuff but you see the basic idea. You wanted to go in and blur the edges of your Roto shape some more, maybe go in and grab the edges and bring it out some like this. Maybe bring the scale of your displays down a little bit. You don’t want it to be too much. There put a little crop on it and you’re good to go.
Just cut-off these bad edges and you’re good to go so let’s take a look at my node tree here. And you can see there’s not much to it to make any displacement heat looking stuff. It’s really easy, let’s refresh one node so you can see it. And that’s it, that’s basically all there is to it. Rhe main thing is changing your channels into the displays node to red and green. So I hope you guys have learned something. I really do, if you have any questions please feel free to get a hold of me. I’ll be more than happy to answer any question that I’m able to, so this is Emeek77 from final cut studio school saying thank you for watching and I’ll see you next time.
