Having believable characters within virtual reality can be one of the most challenging but most important components to get right within a virtual reality experience. Stefano Corazza and Mixamo.com have been working on a set of tools to make it easier to create & animate 3D characters within your virtual worlds.

stefano_headshotStefano talks about some of Mixamo’s services like Fuse to create characters, their auto-rigging functionality, their Decimator to optimize the polygon count, and how they have over 10,000 different animations available in different packs. They also have developed Face Plus to be able to motion capture the facial expressions and emotions for a character, which is the technology that High Fidelity is using in order to translate what your doing with your face onto a VR avatar. gangnam-style

Finally, he talks about the principle of the uncanny valley, and how Mixamo avoids it — as well as the importance of the expression of emotions within VR.

Mixamo also recently updated their Fuse product to make it easier to create 3D characters by making it possible to upload your own content that can be customized with their tools.

They have a couple of pricing options from pay as you go to a $1499/year professional account where you get access to all of Mixamo’s services. Fuse is also available on Steam for $99.

This interview with Nonny de la Peña was by far my favorite discussion from the Silicon Valley Virtual Reality Conference & Expo. It’s moving to hear about the type of emotional reactions that she’s receiving from her human rights-centered, immersive journalism pieces that are experienced within virtual reality. She has some amazing insights into VR storytelling, virtual identity, and the importance of bringing in more diversity into VR.

Nonny has been working on VR storytelling since creating a Virtual Guantanamo Bay prison cell in Second Life in 2009. She started working on with VR HMDs before the Oculus Rift existed, and in fact was a part of USC’s Institute for Creative Technologies when Palmer Luckey was there. Luckey even provided Nonny with a pre-Oculus Rift HMD for her 2012 Sundance showing of “Hunger in LA.”

She’s also worked with Mel Slater, who has explored a lot of interesting effects of Positive Illusions of Self in Immersive Virtual Reality

Nonny has a ton of insights on the components of creating a compelling VR experience from starting with great audio to creating a believable virtual humans. I also found her vision of a tiered VR future of the untethered IMAX-like experience to the Oculus Rift home experience, and then finally mobile VR to be a compelling distinction for the different levels of VR immersion and associated technologies.

For more information on the service that Nonny uses to create her virtual humans, then be sure to check out this interview with the founder of Mixamo.

This is the first of 44 interviews that I conducted at the Silicon Valley Virtual Reality Conference & Expo. I was able to capture over 11.5 hours worth of material from 3/4 of the speakers, 2/3 of the exhibitors and 11% of all attendees, and I’ll be doing a daily podcast over the next month and a half (and maybe beyond). A full list of interviewees is listed down below.

Palmer-LuckeyPalmer Luckey is the founder of Oculus VR, and I had an opportunity to conduct a brief interview with him. I noticed that Palmer’s bio mentions that he founded the ModRetro Forums, and it turns out that there’s some interesting connections between ModRetro and the founding of Oculus VR.

He talks about some of his first and forgettable VR experiences, and the process of starting what he claims is the world’s largest private VR HMD collection. He also covers his connection to the /r/oculus reddit community, the reaction to the Facebook acquisition announcement on Reddit, as well as what he sees as what the future of VR.
