Unbiased Emission and Scattering Importance Sampling For Heterogeneous Volumes


We present two new distance-sampling methods for production volume path tracing. We extend the null-collision integral formulation to efficiently gather heterogeneous volumetric emission, achieving higher-quality results. Additionally, we propose a tabulation-based approach to importance sample volumetric in-scattering through a spatial guiding data structure.

This is an on-demand session.

Learning to Trust - The Making of Raya and the Last Dragon

Tue, Aug 10 11:00 am – 12:00 pm

In this session, our filmmakers show how they collaboratively crafted the extensive lands of Kumandra and filled them with distinctive characters and detail that represent a compelling mix of fantasy and Southeast Asian influences. We’ll reveal the challenge of creating a brood of magical water dragons that rippled through multiple departments. Creating a nemesis for the dragons unlike anything seen before was another task for our effects and lighting departments. All shot through the lens of a story-enhancing cinematography plan that considered every detail right down to the dramatic film grain, all while working from home.

Please unite with us as we detail our collaborative filmmaking process.

This is a live virtual session.

Wrapped Clothing on Disney’s Raya and the Last Dragon


Characters in Walt Disney Animation Studios’ Raya and the Last Dragon wear garments inspired by traditional Southeast Asian wrapped clothing. Using the "Sampot," "Dhoti," and "Bust-wrap" garments as production examples, we discuss what makes them challenging to create in CG and describe novel techniques that we developed to realize them.

This is an on-demand session.

Q&A: Cloth Simulation

Weaving the Druun’s Webbing


The Druun in Walt Disney Animation Studio's Raya and the Last Dragon is a unique creature made out of both a fluid and a web-like structure, and bringing it to life meant overcoming many technical challenges. This talk presents the techniques we used to create the Druun’s webbing.

This is an on-demand session.

Q&A: Dynamics/Simulation

Thu, Aug 12 12:00 pm – 12:30 pm

Q&A session for:

  • Weaving the Druun's Webbing
  • Cooking Southeast Asia-inspired Soup in Animated Film

This is a live virtual session.

Cooking Southeast Asia-inspired Soup in Animated Film


Walt Disney Animation Studios’ Raya and the Last Dragon is an animated film inspired by the people and cultures of Southeast Asia. This talk will describe the collaborative process of designing, simulating, and creating the soup served in the film, which needed to be realistic and visually appealing.

This is an on-demand session.

Mathematical Tricks for Scalable and Appealing Crowds in Walt Disney Animation Studios’ Raya and the Last Dragon


We present specific tools developed for crowds during the production of Walt Disney Animation Studios’ Raya and the Last Dragon: anisotropy in simulations, procedural animation layers, and automatic foot contact labelling by shape analysis. Those tools allowed us to create scalable and compelling crowd performances.

This is an on-demand session.

Populating the World of Kumandra: Animation at Scale for Disney's Raya and the Last Dragon


In Walt Disney Animation Studios’ Raya and the Last Dragon, building the fantasy world of Kumandra involved crafting a broad variety of crowd shots, from bustling floating markets to dragons running on rain drops. We discuss the various workflows and pipelines that the crowds department adopted to address these challenges.

This is an on-demand session.

Q&A: Crowds and Hair

Thu, Aug 12 2:00 pm – 2:30 pm

Q&A session for:

  • Mathematical Tricks for Scalable and Appealing Crowds in Walt Disney Animation Studios’ Raya and the Last Dragon
  • Populating the World of Kumandra: Animation at Scale for Disney's Raya and the Last Dragon

This is a live virtual session.

The Atmospherics of Raya and the Last Dragon


In Walt Disney’s Raya and the Last Dragon, the world of Kumandra is rich with diverse landscapes that draw heavy inspiration from Southeast Asia. These environments require many unique and varied lighting and atmospheric setups. We present the creative and collaborative approaches that help bring these worlds to life.

This is an on-demand session.

Stylizing Volumes With Neural Networks


In Raya and the Last Dragon, a blast of energy rings across an open landscape. To stylize this volumetric effect with harmonic patterns and textures, we use neural networks, whereby effects artists choose a 2D image from which styles and textures are automatically transferred to the 3D volume’s density field.

This is an on-demand session.

Creating Diversity and Variety in the People of Kumandra for Disney's Raya and the Last Dragon


In Walt Disney Animation Studios' Raya and the Last Dragon, the novel approach introduced is modular in both design and construction and includes strategic reuse and refit, in addition to new look techniques developed, for creating the variation and diversity between thousands of crowd assets in the film.

This is an on-demand session.

Q&A: Rendering - Art

Fri, Aug 13 2:00 pm – 2:30 pm

Q&A session for:

  • The Atmospherics of Raya and the Last Dragon
  • Stylizing Volumes With Neural Networks
