Sketchis a singular new fantasy movie starringThe Good Place’s D’Arcy CardenandVeep’s Tony Hale, with some unique special effects, and the director goes into the details of the CG process with other VFX artists.Sketchsees the crayon and chalk monsters drawn by young Amber (Bianca Bell) come to life when her sketchbook is accidentally dropped in a magical pond.

Director Seth Worley recently appeared in an episode ofCorridor Crewon YouTube to delve into this movie’s special effects with the channel’s VFX experts.Worley states that he is “a director who does visual effects"and has a “ceiling” of what programs he is willing to learn to use properly, and worked with many other creators onSketch.

“We did not have lots of money, and let’s find out if you can tell,” Worley jokes.When they are watching the footage fromSketchof the massive crayon monster adorned with googly eyes known as Dave attacking a school bus, Worley recounts the years-long development of the look for this movie, particularly this character. Check out his comments below:

Our goal with these monsters was to make something that was in between flat 2D, like you know two and a half D, drawing look […] I have VFX tests I did as early as 2017. So this is with what was Trapcode Form, now is built into Trapcode Particular. Of course, that’s just a big bunch of particles in a sphere. I just scribbled on paper. […] So I scanned all these in and made a library of sprites, crayon sprites. So those became the particulars that make up that. But the problem is this Trapcode approach was really cool in these wide shots, but it didn’t hold up in close-ups, and it didn’t hold up with like, the rig was really, really limited. Once we started this movie, an artist named Mark Lundgren, we brought him in to help us model the monsters, and ultimately he rendered several of them. He had the idea to just do this in Cinema 4D, to basically, our monsters are cloners built up of these card sprites of those scribbles. And then mixed in there, of course, we wanted them to have this mixed media element to them. So like the googly eye, we rigged it to where we had control over it, but it was also physics-based. So it would, wherever it would point, we’d let it run out of steam at some point and keep falling and flopping around. And if it’s [Dave] running, it’s like the ball’s kind of bouncing around in there, and then the glitter was all particular.

Worley also jokes that he “abused” the use of dust inSketch;the movie features a lot of dust stirring up from the ground or chalk dust coming off the monsters as they move.This comes up again as he discusses the process of rendering the “eyeders,” which are single eyeballs with spider legs. Check out Worley’s additional comments below:

This is a sequence that shouldn’t exist. I don’t know how we got this sequence. So yeah, they’re made of chalk, by the way. So they burst into powder. […] This was an incredible vendor, a partner of ours. And they’ve [the eyeders] all got these little objects. Several of them have knives they’re just carrying upright. They did all of these shots of the eyeders. And I honestly, truly don’t know how they pulled off half of them. But I know that we were constantly saying more dust. And there’s a reason why we had to do all the dust in post […] As these things pour into the house, and as they start fighting with them [the kids in the movie], like the dust will just start filling the air, and it’ll get more and more red. So we bought buckets of this red chalk powder that you see at like Holi festivals or color runs and stuff. […] Obviously that was bad for lungs.

Additionally, the production discovered that chalk dust is flammable, and they switched to occasionally using dyed baking soda, while adding a lot of extra dust in post-production.

What The Special Effects Style Means For Sketch

Sketchwas going for a very specific tone with its fantasy narrative,and rendering the monsters to be somewhat playful is a huge part of that. People will probably assume that there were budget concerns right away when they see this movie, as the designs were clearly not meant to be hyperrealistic. However, this result is also in service of the story.

Clearly,Sketchis seeing great results from its campy, childlike approach.The movie holds a 97% on Rotten Tomatoes, and was at 100% for some time before its wide release. The kitschy visuals are part of the charm, and so long as they are paired with a good story that only takes certain things seriously, it will absolutely be worth the work Worley describes.

Our Take On Sketch’s Crayon Monsters

Sketchis a great movie about coping mechanismsthat finds a wonderful balance and blend of genres, largely due to the hilarious performances of the two lead sitcom stars, as well as the child cast. The way the monsters are rendered helps make it a fantasy adventure unlike any other, and I appreciated hearing about the innovations behind the scenes that went into creatingSketch.
