Many of the shots were extreme closeups, so we had to make sure the tech was invisible to the actors in order to make sure they could focus on their performance,” said Stéphane Grabli.

“Out of over 1750 VFX shots, we had to deliver 500 with full digital head replacements. The stakes for visual fidelity were higher than ever due to incredibly up close and personal camera work. Capturing the performance with the highest accuracy was the priority and our modeling and compositing artists had to be mindful of this when using Facefinder for reference,” explained Stéphane. For The Irishman we’re not trying to make Robert De Niro’s character look or act like any of his past characters, for example, Ray Lamotta from Raging Bull - instead we’re aiming to match De Niro’s performance to a younger version of Frank Sheeran. CINEMA 4D shaders are immediately available in RenderMan, and RenderMan shaders can even be used within CINEMA 4D as long as a compatible render engine is.

furthermore contains some tutorial how to create 1) a graphical widget and 2) a pipe. “This subtlety marks an important difference between The Irishman and Star Wars for example, where we needed to match the exact performance of Carrie Fisher as Leia. Ayam is a 3D modelling environment for the RenderMan interface. Ultimately, this performance would be retargeted onto a younger-looking version of the facial rig for final rendering in RenderMan,” added Stéphane.Īlthough this data automation was crucial for the de-aging process, Scorsese didn’t want the performances to mimic that of their past characters, but to bring youth to the character’s performance in The Irishman. “Motion too subtle to be represented as shapes was captured by Flux as per-vertex deformation. The shape library was produced by the modeling department through the referencing of a large library of past performances from the actors and with the help of an AI engine, dubbed ILM Facefinder, to efficiently sort through the data,” explained Stéphane.

“We then ran this data through our new in-house software called Flux, which would analyze pixel values on principal photography footage as well as infra-red footage, to capture the performance of the actors and transfer it onto a shape-driven facial rig to produce animated 3D geometry. Most endermen traps are best suited to the End or warped. This angers any you look at, luring them into the trap. I took a picture of dust by emptying my vacuum cleaner on a glass plate, then projected it on a subdivided plane, cut the geometry using the dust mask, and optimized/sorted the dust grains. It is possible for the user to create such a trap that can be used by simply standing still, and looking at the endermen. My process for the dust was very straightforward. There was no traditional animation used on The Irishman, thanks to an intricate retargeting solution that allowed them to capture incredibly subtle nuances in performance. The purpose of an enderman trap is for the easy access and killing of endermen. PRMan's area lights support light filters, as well as light-linking, groups, per-group AOVs, and IES profiles and portals.The innovative camera rig can capture infrared light Analytic Area LightsĪrea Lights are a powerful way to create physically accurate lighting while optimizing sampling budgets and, in turn, performance. The streamlined interface for creating AOVs and custom LPEs is the single location to define the outputs you need for post processing workflows.

Change styles, colors, and more while results update continuously. Using Xgen's native interactive grooming tools, get immediate feedback on your creations.

Render more quickly than before! Tuned to improve speed and agility, the RenderMan ray tracing core lets users make decisions as they work. We now supply the relevant controls in a RenderMan rollout on Maya nodes, eliminating guesswork and clicks. It's no longer necessary to add RenderMan attributes one-by-one in the interface. Make scene changes, edit parameters and more without having to restart the render. The goal is to provide a standard mechanism for modeling and animation software to send data to rendering systems in a device- independent way, and with minimal regard to the actual rendering algorithms being used.

Now you can render interactively directly to the Maya viewport by choosing RenderMan as your renderer. RenderMan is in many respects similar to PostScript, but for 3D primitives. Similarly a renderer that complies with the standard specifications of RenderMan can use Z-buffer, scan-line, ray-tracing, radiosity or any other method to 'draw' the objects, and this step is independent of RenderMan.

In other words, a modeler should not be concerned with the rendering step. Change parameters, import or update assets, update options, and even change LPE while seeing your results update. RenderMan lets 3D artists to specify what to render but not how to do it. Your changes are immediately rendered from Maya without an intermediate stage or exporting to RIB.

Get more done without having to start a new render.
