Filmmakers producing Google Spotlight Stories need tools to support their creative visions and Google provides them with the technical expertise. Along with producing plugins for Maya and Pro Tools, Google has developed a proprietary software program that helps with the end-toend production of VR stories. “Story Editor is a custom visual tool to create and edit non-linear stories starting from animation clips or videos,” explains Google Spotlight Stories technical project lead Rachid El Guerrab. “This also includes tools to edit and control object-based or Ambisonic audio and its interaction with the viewer.” A rendering and animation engine was created because none of the offthe- shelf solutions provided the right amount of flexibility or performance. “This enabled us to shrink it to almost the size of a video codec, which allowed…

If you’re new to CGI you may feel that there are far too many tools to choose from in a dizzying array of software. This series aims to break everything in CGI down to the very basics, so that every artist can be armed with the knowledge of which tool is best. This time we are looking at the knife function. It goes by many names: knife, slice or cut to name but a few, but effectively the implementation is the same – it cuts through polygons and edges to either split objects up or to create new boundaries within a mesh from which to create new geometry. A good slicing tool should enable an artist to cut either in a way that is sympathetic to the existing geometry or…

Matthew Wind, Bristol, UK FOLLOW THE VIDEO www.bit.ly/vault-228-VR Oscar Juárez replies Creating archviz in Unreal Engine 4 is getting a lot of attention these days. We have many options for this in the software, but here we’ll explore what we can achieve with blueprints. We will create an interactive blueprint to provide us with a light that we can turn off and on. EXPERT TIP KEEP THEM BOTH VISIBLE Try to have detached the Blueprint tab and place it so you can see the viewport of your blueprint and the viewport of the level. This way all changes you do are visible in real time and you can adjust light and text easier.…

INSIGHT News and views from around the international CG community In an ever-competitive industry, the key to the success of a studio often lies in finding and occupying the right niche. And Territory Studio, a small studio based in Clerkenwell, London, has done just that. Formed by industry veterans in 2010, the studio’s biggest strengths lie at the intersections between motion, digital and graphic design. One of the specialisms it has become best known for is the art of designing on-set interfaces. In other words, whenever an actor is seen interacting with any kind of computer software – whether that’s a traditional terminal, a tablet device or a futuristic, holographic projection – Territory designs what’s going on within the on-screen screen. And it does this in a way that integrates…

She is currently collaborating with AMD as technical artist for Radeon ProRender for 3ds Max. www.twitter.com/cirstyn FEATURES Flattening tool for onfigure drawing Kitbashing with clothing libraries Stitching details Outside edge darts UI improvements FUN AND EFFICIENT FEATURES What I enjoyed most in this release was working with the flattening tool. It was just so much easier to generate garments to measure when you can block them out that fast and easy – especially when you can build libraries for entire figures and animations with its new kitbash library. First of all, it seems CLO3D, makers of Marvelous Designer, are starting to listen…

MEDITERRANEAN TOWER RUINS ARTIST Elias Tsirides SOFTWARE Unreal Engine 4, Photoshop, Maya, ZBrush, Substance Designer, Substance Painter Environment artist Elias Tsirides has been dedicating his time to a Byzantine ruins environment creation over these past few months, and this image is only part of their larger project. “I love the process of gradually fleshing out something out of nothing in the proverbial blank canvas,” he explains. Elias utilised a range of 3D software to create the various materials; the individual rock pieces were sculpted in ZBrush, which were then grouped and textured in Substance Painter. After bringing this into Maya, a square wall unit was built in a tileable manner. Elias begins his work on a project by seeking out relevant references while listening to music of a similar mood…

Particle systems are one of the main components of full-featured digital content creation software. While Cinema 4D does have a particle system, it is slow and does not have an intuitive workflow for anything other than basic simulations. This flies in the face of one of Cinema 4D’s greatest strengths, which is its shallow learning curve compared to many of its competitors on the market. Thankfully, Insydium came to the rescue with the X-Particles plug-in, which offers everything that the Cinema 4D particle system could be (and more). In fact, it can be argued that the reason there has not been much development of Cinema 4D’s own internal particle system is that there is no need, as X-Particles does such a stellar job. It is not just that X-Particles offers…

Antony Ward replies The best rigs are intuitive and simple to use. When building them you must remember that it’s possible it will be used by a whole team of animators, all of which will have their preferred approach to bringing things to life. Overload a rig with too many controls and you’re not only making it more complicated to use, but you’re adding to the amount of time it takes an animator to create the simplest of sequences. One element of rigging that can help is to build in the ability to pick-walk through the hierarchy. This enables the animator to quickly navigate the rig by using the arrow keys, rather than selecting controls or digging through the Outliner. As an example, if you have the hand control selected…

FEATURE VR: changing the story When using virtual reality as a tool for crafting entertainment experiences, the tried and tested process of storytelling is disrupted somewhat by the fact that the audience is now firmly in control of what they see and what direction they take. It’s changed the game, and that’s something that has to be at the forefront of any VR creator’s mind. Collaborating with various filmmakers to produce diverse content that pushes the boundaries of storytelling and technology within the realm of virtual reality is the primary objective of Oscarwinner and Google ATAP director Jan Pinkava, who created the first of the Google Spotlight Stories four and a half years ago with Windy Day. “VR is this immersive and potentially interactive space that is pushing at the…

The power of material scanning cannot be overstated. When done properly, it is the most accurate way to digitally reproduce a physical material available to us today. For a long time, however, the only way to access it was with a high-end scanner, which many people in the 3D community do not own. Allegorithmic couldn’t buy everyone a scanner, but we could open up the technology to more people. And the exciting thing is, the research has paid off. In February we launched Substance Designer 6, which included a complete scan processing workflow that finally enables anyone with a smartphone to scan physical materials. In this tutorial, I will describe each step of the scanning process, from the photoshoot to the final Substance, incorporating insights that we’ve learned over the…

EXPERT TIP REFERENCES FOR EVERYTHING The main elements for the terrain creation are the references. These will be very useful during the sculpting and painting process, helping you to achieve the best result. FOLLOW THE VIDEO www.bit.ly/vault-228-VR Pietro Chiovaro replies The creation process of a realistic terrain can be divided into two parts. In the first part, we need to search for relevant references for the terrain we are going to create, sketching a concept of the entire scene. In the second part we have to create all the models that compose the scene in order to create the terrain. For the creation of this particular scene I tried to imagine the terrain of Mars. To do that, after the concept creation, I created a little library of images that…

MA,. OBJ and. FBX formats All meshes contained in a single file KITBASHING The term ‘kitbashing’ dates back to the early days of sci-fi modelmaking with the likes of Thunderbirds, 2001: A Space Odyssey and Star Wars. To save modelling all the tiny details on vehicles and buildings, commercial plastic kits were used – for example, the surface detail on the original Star Destroyer is an amalgam of battleships, submarines, fighter planes and Russian T-34 tanks.
