The VFx Superheroes Making Super-Powers for ‘Project Power’
MANY FRAMESTORE ARTISTS WEIGH-IN ON THEIR CONTRIBUTIONS TO THE NETFLIX SHOW.
We all realize it takes many artists to ship visual effects for an enormous movie or tv show. Which is why I needed to get a number of views from the group at Framestore for the way they realized the visual effects for Henry Joost and Ariel Schulman’s Project Power, which just lately premiered on Netflix.
Here, artists from totally different areas of the studio—CG, FX, compositing and extra—talk about their explicit challenges on a spread of super-power pictures within the movie.
Man on Fire
Jimmy Leung, lead FX TD
Project Power was the movie that had essentially the most fire pictures throughout my time at Framestore. In the very starting, we had been attempting to match the reference of a stuntman with low temperature fire. Once we acquired the same behaviour, we began to alter it a bit in order that it was extra stylized for each the film and storytelling. We additionally acquired some layers such because the boiling skin and boiling water from his skin that you simply may not be clearly seen within the film, however actually helped to make it look realistic.
A giant problem was conserving parts constant throughout the entire pictures. We had quite a lot of parts comparable to hearth, smoke, steam, embers and ash. Keeping the stability and continuity for these parts throughout fairly an extended sequence was an vital job to ensure we maintained the storytelling. A generic arrange was made after which utilized by all artists so we might assert that we had been producing constant information throughout the entire pictures. It goes with out saying that we had an excellent crew to assist get the job performed. We additionally tried to match the sims pixel values to the plate fire which is simpler to show down the shot and have the fire act in a pure way.
For our main sim, we cleared all heat that may have gotten trapped inside the collider throughout the simulation so we didn’t get any artifacts. It was difficult to take care of hearth in entrance of a fast-paced character, so we included one other native house simulation with world forces utilized to it. This allowed Houdini to unravel our fire simulations a lot simpler in opposition to a extra static object which was then moved again to world house.

The sequence features a few kinds of hearth: the fireplace on the character’s physique, the fire surrounding the environment, the fire/explosion where Newt overdoses and explodes within the bathtub. For the fire on Newt’s physique, we divided it into completely different elements of the physique, so we didn’t have to sim all the things once we had suggestions. We had head fire, facefire, physique hearth and LED hearth. The LED hearth was to cowl the precise LED lights the movie crew connected to the actor, with a purpose to gentle the character realistically. So we had this further ingredient the place we paint over where the LED lights are situated to ensure there’s fire on the realm to match the sunshine. We additionally had fire for the ash coming from Newt’s physique so as to add extra particulars. We then had fires for the environment, wall fire, couch fire and fire for the ceiling fan.
The problem we had for these components was that, as a rule, there’s actual fire within the plate, and we wanted to match them so our CG fire didn’t look fake. Another problem we had was consistency, since there are a lot of connecting pictures that each one have fire so there wanted to be a great continuation. Sometimes, they don’t match correctly, and we might add additional fire components to cowl the non matching half as to not have to re-sim the opposite half which had already been accredited. We additionally had some technical points with the render time, as typically the fire was very near the digital camera and there could be too many fire components as nicely, so it took quite a while to render.
We labored intently with lighting to determine a technique to save render time by combining totally different fires and lowering the LOD used as quantity gentle. It considerably helped reduce render time, with very satisfying outcomes. We had an excellent setup general, and due to the division of the a number of components, typically we’d even work on one another’s pictures when some have been too busy. It was a terrific team and we had an superior Lead and a wonderful supervisor. It was a brilliant fun project to work on!
Jeremie Ducrocq, compositor
One of the vital ideas on Project Power was to maintain the imagery grounded in actuality. The general VFX supervisor Ivan Moran did a tremendous job discovering real life references and interpreting them throughout the context of human superpowers.
For our Camo Guy, the principle reference was the cuttlefish. Cuttlefishes have the power to change their skin and alter shade and pattern like a chameleon, which may happen inside a few seconds. Those couple of seconds create a delay within the background he’s assimilating when transferring, which makes him camouflage quite than grow to be invisible. On set, the actor was solely wearing a mini short, so we might get an ideal reference on how the sunshine was reacting with his skin and use these shadows in ultimate compositing.
The first step was to rebuild all of the background to have the ability to take away the actor when he’s camouflaged. Our paint workforce right here at Framestore did a tremendous job because the work was typically extraordinarily advanced, with a number of folks wanted for the total reconstruction. Simultaneously, all of the pictures have been bodytracked so we might exchange the whole body and have full management on the transferring pattern when the character was working round.
We determined to make use of a hybrid strategy to combine the background patterns and the sunshine interplay with the surroundings on Camo Guy’s physique. All the shots have been lit to match the supply plate as shut as potential, and we have been rendering the digi double with a traditional skin shader. On high of that, we have been outputting a whole lot of utility passes the Comp group might use to undertaking the background onto the character with totally different patterns and blend it with the skin shader, whereas nonetheless preserving all of the muscle stimulation from the CG character.
The massive benefit of that alternative was to have the ability to control what the Camo man was mimicking in Nuke, with out having to run costly CG renders each time. The speed of sample change was depending on the extent of agitation of the character. It was essential to have the ability to management it and have direct suggestions of the end result and a fast turnaround to have a look at the character within the context of the sequence. This undertaking was very particular as Framestore was concerned very early within the course of. Looking ahead to what’s going to come subsequent and why not preserve pushing the Project Power world!
Frank gets shot
Kevin Sears, CG supervisor
From the start, the Frank Bullet shot was pitched to Framestore as an enormous spectacle second within the story. It was a fantastic alternative to have VFX straight assist the narrative and reveal Frank’s power.
In the turnover for the scan, we mentioned for two hours the significance of supporting and never changing the wonderful element in photography that was filmed with a Phantom digicam at 900 fps. A witness digicam sadly wasn’t excessive pace, however it offered a take a look at the a number of takes the actor did utilizing an air stress jet to create the unimaginable wobbling particulars across the eye and cheeks in lower than 1 second. The scope of the work targeted on including a bullet impression inside the identical epicenter of the air blast and altering the timing of the hair being affected, which was not showing motivated by the impression on the face.
This required matchmoving Joseph Gordon-Levitt and first constructing a excessive res digital double. We began with a photogrammetry scan and likewise sourced pictures from the movie “50/50” (the place he shaved his head) to seize the true form of his cranium. Using ideas from manufacturing, we started including layers of hardened skin as blendshapes to stage the delicate strengthening of the skin through the moments of impression. As it progressed, the character of the ripples advanced throughout the face from a really fluid motion right into a slowed and stiff wake and finally melted again into the unique face. We timed all the blendshapes with a whole lot of finesse in maps that overlapped and rode on high of a fluid sim that we projected on the face from the POV of the bullet.
Each ripple wave had distinctive timing to hook as much as the scan ripples and decreased their pace and amplitude in every subsequent repetition. Concurrently, we would have liked to boost the deforming areas on the face that we by no means wished to switch, with the same collection of skin texture maps primarily based on these hardening appears to be like. This required a devoted artist to sculpt almost 150 frames to match these shapes for therapy in compositing. The hair on Joseph Gordon-Levitt is totally digital all through the shot, with an enormous a part of the problem to match the look carefully to the actor whereas permitting it to maneuver appropriately as soon as huge forces can be utilized to it in gradual movement. The bullet was squashed with a blendshape achieved by the animation group. The gun muzzle flash was naturally digital and pushed by excessive speed reference that the FX group actually frame-matched to get the distinctive smoke curling again towards the barrel. Additional sweat and spit sims have been added by FX as effectively. Finally it was rendered in 4k with Freak, Framestore’s renderer. I’m extremely happy with all of the departments at Framestore that got here collectively to boost this wonderful character power!

In the story, this character has a tragic death as a gun battle rages exterior and he or she freezes the whole lot inside a glass construction to sub zero temperatures. It was notorious within the halls at Framestore and drew the eye of many staff curious on the scope of labor required within the shopper transient. This was all captured in a single steady take and over two minutes in size, with solely minor retime sections to place concentrate on foreground and background action.
Our philosophy was to embrace the performances on set and never exchange the actress as a full CG digi double. This grounded the motion in one thing that wasn’t artificially constructed and we saved a lot of her face, costume and hair on Frozen Girl from the unique scan. This meant that our Tracking division had an infinite problem to tightly capture body and face motion. Rigging and Modelling groups managed face mix shapes that have been dialed in with matchmove artists helpful particularly in efforts on the final death crawl part. BodyTracking lasted for a number of months with references utilizing GoPro witness cameras that allowed matchmove even on sections off digicam when she was solely reflecting into the home windows.
On set it was continuously flashing over 90 gentle sources, every with a special hue and publicity per body, over 3,500 frames. We arrange a Lighting system that sampled the witness digicam reference to drive the lighting timing by way of Nuke, which acquired about 60% of the best way, the remainder was achieved by tweaking with the ultimate bodytrack to match the Frozen Girl digi double. That course of took about two months of keying a dynamic gentle rig by hand.
We additionally matched little imperfections on set. For instance, we tracked the motion when plexiglass warps and shifts out of the icebox and used that geo in order that FX would react to each hit on the construction. Major shifts on the glass drove the ice sheet collapsing and regrowing as the whole construction is roofed in ice by the top of the body vary. Timing of the ice components have been augmented with Textures that included directionality of the generations in ice development. This was coupled with numerous phases of frost shaders and refraction passes that allowed additional developments of ice accumulation over background motion in Compositing.
Framestore accomplished a sequence of key artwork frames with our FX Visual Concept workforce that established the milestone moments together with Comp to set the temper of every development on Frozen Girl. The dry ice sims poured off her uncovered skin areas and we ran choices to get the burden and density appropriate with the dynamic lighting. Internal cracks have been generated as geometry contained in the ice skin layers in key areas and timed creatively to create the sense that the shell on the skin was breaking and freezing again collectively. The idea of the ultimate ice masks on the face started with a graphic thumbnail storyboard in black and white that depicted an enormous ice spike rising out of a death scream. That set the tone for the extent of horror and I feel the FX workforce had a enjoyable time including in all of the gildings.
Thomas Martin, lighting lead
Frozen Girl was probably the most advanced and troublesome sequence and lighting state of affairs I’ve ever labored on. There have been roughly 90 lights contained in the tube in addition to exterior set lights. For the 90 tube lights, every one had a special hue and publicity, every body over 3 500 frames. We arrange a system that sampled the reference footage to drive the lighting by way of Nuke. Which acquired about 60% of the best way, the remainder was going body by body and hand keying every part and particular person gentle to match the actress to our digi double. It was about 2 months of keying by hand.The rendering facet was a mixture of 2D distortion passes in addition to 3D ice, particles and quantity renders. As effectively as plate projection to recreate the refraction of the ice on the partitions. It was extremely satisfying to see the ultimate end result.
Alicia Etourneau, FX technical director
I’m thrilled to have had the chance to work on Biggie’s rising tumor impact. It was an attention-grabbing problem, and a terrific collaboration between departments.
At first, the FX group was solely supposed to create the veins and tumors system. The Creature FX division would then use it to stretch the skin on prime of it. We rapidly realized that as a way to keep away from penetrations between the veins and the skin, we needed to significantly subdivide the mesh. The extra detailed the veins, the extra subdivisions the mesh needed to have, which vastly impacted render time. To keep away from this case, we determined to deal with the skin deformation instantly as an alternative of utilizing a dynamic simulation.
VFX supervisor Joao Sita led us for the creative elements of the form, measurement and rhythm of tumors rising so as to add dynamics to the scene. We drew the veins, based mostly on anatomical references, on prime of the unique skin. Then, we animated the expansion of the veins and the tumors. The last step was to deform the skin so it overlayed the excrescences.
The problem was to keep away from penetrations as Biggie was transferring rapidly. We additionally collaborated rather a lot with Lookdev to offer them with parts they wanted for the creation of the great skin shader, in addition to CFX, to regulate tumor positions and permit them to spotlight Biggie’s material tearing.

The Art sequence which we ended up coining “Power 2.0” right here at Framestore (as a result of it was the second most large sequence we labored on for the movie), was an thrilling problem and a bit daunting in the beginning. The concept was to point out a excessive frequency wave-like force that emanates from Art. This force is so intense that it actually transitions the encircling rain via a number of states of matter – liquid to gasoline to plasma.
The VFX supervisor needed to point out the impact taking place at a macro stage on particular person falling raindrops earlier than pulling out to wider photographs and exhibiting the extent of the harm. We ended up working in 2 groups to make issues somewhat extra bite-sized. The first group labored on the impact at a macro stage exhibiting the droplets transitioning via their atomic states. The second group labored on the extensive photographs exhibiting the plasma flying outwards from Art like coronal mass ejections.
For the raindrop transitions there have been a few huge key photographs. One shot exhibiting the water rising from the puddles round Art’s ft because the power is constructing, and one other shot with the digicam pulling away from Art because the droplets start their transitions with the digicam lastly macro specializing in one hero drop that explodes into plasma. We used Flip Fluids in Houdini to deal with lots of the puddle and droplet efficiency.
When the liquid transitions to gasoline/steam we handed the efficiency to the Pyro solver in Houdini and easily added lots of temperature on the finish when the droplets turned to plasma. It was lots of fun to work on the transitions as a result of it required an interaction between particle, fluid, and smoke solvers on the identical time. We additionally performed with lots of completely different forces to push and pull the droplets round as they oscillate.
For the wider shots the look was completely different however related strategies have been utilized. The VFX supervisor needed the sensation of the plasma to be like coronal ejections on the floor of the solar. These ejections have a really liquid-like efficiency but in addition share some characteristics of gas. It was powerful work arising with one thing that didn’t appear like an explosion, however shared a fire and liquid-like efficiency. In the top, the group did an awesome job and ended up utilizing a mixture of particles, fluid, and smoke solvers to attain the look. Many due to the look-dev, lighting, and comp departments who additionally performed an enormous function in getting all the results to sing!
