Chaos Group launches V-Ray for Houdini

 

During SIGGRAPH 2019, the Chaos Group has released V-Ray for Houdini, a massively useful render for the assembly of creative scenes in a procedural environment. V-Ray for Houdini has been used in productions already, including in a video music clip by Ingenuity Studios, who have been using it since 2017 to create high-profile pieces for Billie Eilish and The Walking Dead.

 

“We started using the alpha build about 30 minutes after it was released,” recalls Grant Miller, owner and VFX Supervisor at Ingenuity Studios. “We wanted to move scene assembly into Houdini, so we’d have more control over our instances and a tighter loop on VFX and look dev. If V-Ray for Houdini could take us there, we were all in.”

Taylor Swift

V-Ray for Houdini’s first test was on Taylor Swift’s “Look What You Made Me Do” video, whose CG snakes helped Swift poke fun at negative press and earn over a billion views. From there, its growth was organic, as new features and boosts continued to win over artists used to working with Maya and Mantra.

 

“I can’t speak enough to the responsiveness of the Chaos team,” said Miller. “They turned around countless features and bug fixes in no time. Their dedication to making V-Ray for Houdini a first-class integration is a big source of confidence.”

 

After the success of “Look What You Made Me Do,” Ingenuity were tapped again for Swift’s next video “…Ready for It?”, a Ghost in the Shell-inspired affair that had to pack robot faces, digital eyes, magical orbs, energy blasts, lightning and shattering glass into three and a half minutes. The ambitious video also had a set piece – a glass box – that had to correctly refract Swift and the effects around her at all times.

Since the team was still transitioning to V-Ray for Houdini, the box setup was created in V-Ray for Nuke, with the shaders and textures for the glass kept live so that refraction and reflectivity could be tweaked as needed on a per-shot basis. The VFX work was then completed in Houdini with .vrscene files exported for later use in Nuke, allowing the team to do look dev on the lightning and clouds in Houdini with full trust that everything would match when rendered, since V-Ray was used on both applications.

Having proven their prowess with glass boxes and pop stars, Ingenuity was an easy choice for Interscope Records, who also wanted a glass box around Billie Eilish and Khalid for their single, “Lovely.” This time, the glass box and visual effects would take center stage, as “Lovely” would be shot entirely in one take using green screen. As the song progresses, Ingenuity’s effects would play off the glass box metaphor, calling back to the sadness of the lyrics as creeping frost and rippling water hold our subjects in.

“Billie and Khalid needed to be integrated inside the glass box and subsequently refract through it,” said Miller. “By exporting .vrscenes from Houdini and rendering with V-Ray for Nuke, we were able to keep their keys and roto live, making adjustments as the video progressed without the need to render updated keyed footage and round-trip it back through CG or FX. Having the flexibility to easily send assets and FX from one package to another made this all possible.”

 

Ingenuity used V-Ray for Houdini for look development. The interplay of glass box and VFX made Houdini a prime tool for experimentation, allowing the team to populate their environment with clouds, lightning, water, frost and splashes and see what worked best. After decisions were made, the studio rendered scenes as they saw fit, sometimes in Houdini, sometimes in V-Ray for Nuke, giving Ingenuity more flexibility with their pipeline and Eilish 303 million views and counting.
V-Ray for Houdini is available now for Houdini and Houdini Indie 16.5.473 and later, with support for Windows, Linux and MacOS. Licenses are available for US$80 a month and US$470 annually.
