Revealing The Secret Of CG Double In Logan

While The Fast & Furious 7 was released in 2015, with it came another blockbuster Rogue One in 2016, the entire succession of movies fire up to certain crisp discussions about the CG aspect digital revivification of the deceased actors.



On this front, the CG build up Double of the deceased Paul Walker in Fast & Furious ignited debate anew about the significance of the digital actors in the sector of filmmaking.

And this debate is probably to not discontinue in various other following films in 2017 and 2018.


To begin with the latest version of such extravagant digital double it is important not to miss out the creation of a digital double for Hugh Jackman and a new mutant Laura (Dafne Keen) for a few scenes in Logan.

The movie is James Mangold’s latest entry to the series of the X-Men and Wolverine franchises.

The movie consists of a key story point that has Hugh Jackman as the lead character.

It discovers the continuation and existence of an artificial mutant with the DNA of Hugh Jackman with the conveying healing powers and precarious claws.

This implied Jackman would show up in scenes as both Logan and X-24.

Different scenes, for the most part, activity ones, likewise influenced utilization of advanced Logan to head substitution and a computerized Laura.



When Hollywood has been reckoning on digital doubles for past years, the work in Logan is especially consistent, however, it is regardless of whether the scenes are moderately short and don’t include a symbol conveying any discourse or dialogue mentioned in the script.

The film is possibly another case of where things are going with digitally computerized actors and the methods how they can be utilized to help recount the stories directors are craving to tell.

The entire team of the Cartoon Brew sat down to discuss the several strategies that had been followed during the shooting of the movie as well as the digital tasks to be performed by the artist.

Cartoon Brew had a discussion with the studio, Image Engine, about the various computerized Hugh Jackman and Laura.


Image Engine in Vancouver had worked under the famous VFX director Chas Jarrett, to examine how the CG ‘digi-copies’ were enlivened and animated.

In the wake of being given the errand of re-creating CG heads for Dafne Keen and Jackman Image Engine’s group quickly comprehended what it was up for.

The biggest challenge for the production team was to make the digital double as everyone is well acquainted with Logan, to make a realistic digital double is not an easy cup of tea.

The Visual Effects supervisor of Image Engine, Martyn Culpitt revealed to the Cartoon brew that they are accurately taking a gander at the genuine Hugh and a computerized Hugh one next to the other in a few shots.

The studio had finished a lot of advanced digital human-type work previously, yet generally as either human-esque beings or as CG stunt pairs – never full-outline performing artists expected to be unclear from the genuine on-screen character.

That implied Image Engine needed to increase on their advanced human pipeline, while likewise gaining by work they’d beforehand done in the territory.

“We essentially needed to manufacture the entire framework sans preparation,” said Culpitt.

Analyzing the Process


In the movie, Hugh Jackman portrays the character of both the role of the X-24 and Logan and here we are going to discuss the various processes that the artists took to achieve the digital Logan and digital Dafne Keen.

From the live-action on-set shoot to the step of filming it, from the special type of scans (of the actors) to the active facial rigging and Animation, all challenges were successfully performed by the artists of the crew.

Even the final rendering and final compositing are done with absolute precision and proficiency.



Furthermore, the studio employed in de-aging Visual Effects for few of the Jackman shots.

In these shots, the video stream of the actor is would be supplemented and reinforced to make him look like the younger X-24.

Potent Planning

Prior to entering the utilization of digital head substitutes, especially for the Logan and the X-24 characters, the overall VFX supervisor Chas Jarrett affianced Previs studio Halon with a view to animate an entire series of the scenes in which numerous Jackmans would arise and appear.

The Halon Previs supervisor, Clint Reagon is of the view that this will give Chas and Mangold an advantage for how to shot for selections would affect the shooting schedules and Visual Effects.

The Shooting Process


At the time of the live-action filming, some distinct type of technologies, as well as methodologies, were utilized and employed that would possess digital face and head substitution.

A system was set that the stand-in actors wore dots on their heads.

As for example, the scenes of Keen’s stunt doubles where they were engrossed in the fighting and the sequence within Logan’s limousine while he was trying to escape.

On account of staircase scene in which Logan experiences X-24 out of the blue, Jackman played out the part of Logan at the base of the stairs while a trick twofold played X-24.

Afterwards a reference plate was shot that was similarly made up of Jackman doing X-24’s developments in his X-24 make-up.

Subsequently this would be utilized to test the right lighting on the last CG head.

That specific shot, similar to all the advanced head substitutions, required cautious match-moving and following by the group at Image Engine, particularly as the trick twofold’s physicality was diverse to that of Jackman.

Complete Scanning of CG Effects



Thereafter, the filmmakers took benefit of a long time to research in the subject matters of image-based lighting and the crafting of photoreal virtual humans.

For this, they took directions at the University of Southern California Institute for Creative Technologies (USC ICT) with regard to procuring scans of Jackman and Keen’s face.

On account of this, a photogrammetry rig was utilized to obtain full body proportions and textures.

The scans of the facial region of the actors were executed within the recent personification of USC ICT’s light stage.

Here numerous lighting conditions can be simulated at the time when an actor performs distinct Facial Action Coding System (FACS).


All angles of face shapes are captured numbering to maybe 64 in all total.

Strikingly, Jackman was requested to shave his trademark Wolverine hair and sheep hacks for the light stage methodology to enable sweep however much skin to detail as could reasonably be expected.

“The reason we did that is then we’d get all the more detail on his button and have the capacity to see his mouth and jaw shape,” said Culpitt.

Out of the outputs, Image Engine got crude photos of Jackman and Keen from various points, in addition to CG models of the performing artists in each FACS posture, and distinctive lighting passes (reflectance, diffuse, and so forth) for each model.

At the final part, the eyes are solved for the purpose of the digital actors and this is one of the crucial parts of the entire CG section as they will determine whether the shots are performed successfully or not.

The Completion Touches



Here, the credit of the final touches goes to the Image Engine’s proprietary as the lighting of the CG actors was tackled utilizing Gaffer toolset.

Yuta Shimizu is of the opinion that the created a lighting template that allowed our artists perform an entire pack of iterations, that had let them survey things ingeniously right through Animation into rendering.



The studio received Solid Angle’s beam following Arnold renderer for the task which supported in accomplishing the correct level of skin shading and sub-surface scrambling on the appearances.

They likewise actualized a framework by means of the creation administration programming Shotgun to convey the privilege CG show at render time to accommodate the different expresses each CG head and body must be in, contingent upon how much harm and wounds were essential.

“Now and then the shirt is tore, or there’s blood here, a scar there, or an alternate haircut,” clarified Shimizu.


If you have seen the digital Benedict Cumberbatch in Doctor Strange, then you will more clearly understand the digital world of Logan.
