CG art to inspire ARTIST SOFTWARE Maya, ZBrush, Photoshop, Mari, alShaders (Arnold for Maya), texturingXYZ Senior modeller Aldo works in the film industry at ScanlineVFX, and spent around 80-90 hours creating this beautifully realistic hitchhiker character with attitude. “I rely a lot on camera lineups, which is common practice in the VFX modelling environment. It’s helpful when there is no scan information and we only have to use photography or concept art alone to model a character, prop and environment.” Aldo says that typically, when creating artwork such as this, he will begin by heading into Maya, where he will create a camera and line up the model to help him achieve the correct measurements, like focal length and distance from the camera. “Since I was basing the model on…

CG art to inspire ARTIST SOFTWARE ZBrush, 3ds Max, V-Ray, Ornatrix, Mari, Photoshop, Marvelous Luis works as a 3D artist and art director at Serial Cut, and to challenge himself in creating likeness images, he created this uncanny portrait of American actor John Malkovich. Describing his image-making process, Luis says: “Typically I start gathering as many good refs as I can. Then I move to ZBrush and start from a base mesh at the lowest subdivision level, adjusting the proportions of the character and trying to match the reference photos. A good habit for me is to match one photo and cycle to the next one until it looks the same from every angle. It is really important to get the likeness working at low subdivision level. I projected a photo of…

STEP BY STEP CREATE A SWIRL VDM 01 SCULPT THE SWIRL To start off, we first need to get a canvas, so head to Lightbox> Project>MISC and select the Brush 3D template. With a clay brush selected, build a little hill in the middle of the canvas, more or less to the size of the swirl. Now, with the radial symmetry on and DamStandard brush selected, start sculpting the grooves and peaks of the swirl shape. 02 FIX DISTORTED EDGES Make sure to stay away from the edges of the plane. If you accidentally mess up the edges, you have to fix them before saving the VDM: mask the edges, invert mask, go to Tool>Deformation>Relax Plane Grid or Morph to Grid, depending on the level of damage caused to your…

Oscar Juárez replies When creating architectural visualisation you need to represent a lot of details, and one of the most time-consuming is vegetation like grass, trees and bushes. In this simple tutorial I will show how to quickly create grass in Unreal Engine using a low-poly mesh. Let’s get to it. FOLLOW THE VIDEO www.bit.ly/vault-230-jedi STEP BY STEP CREATE GRASS WITH A LOW-POLY MESH 01 IMPORT BASE LOW-POLY FBX AND TEXTURE Our first step will be importing our low-poly base mesh. I used just two planes here. It’s so important that you map them first and then export, as this will make things so much easier later, and as usual remember to set units to mm so we can export the correct size. Once imported we will have our FBX…

The Star Wars prequels of the early 2000s were widely criticised for what the public saw as “too much CG”. But Cheetham believes that was a different time, and the debate has now moved on. Nowadays, good CG is so invisible that it’s less about the quantity, and more about the quality. “CG in general has moved on, whether it’s a Star Wars picture or anything else,” says Cheetham. “That’s partly down to software advancements, but also it’s down to the talent. People studying how light falls or how a texture should be created, the materials of an object; I think these days there’s a lot more knowledge brought back from the set to the studios. On The Last Jedi, we certainly had a huge source of information from ILM…

CG art to inspire ARTIST SOFTWARE ZBrush, Modo, Marvellous Designer, Substance Painter, Photoshop Peter Sandeman, 3D artist at Blackmagic Design, created this charming 3D image based on an illustration by Tom Booth (@tomwilltell). The boy’s T-shirt was modelled in Marvelous Designer, tweaked in ZBrush and then brought into Substance Painter for texturing. “The hair is sculpted in ZBrush using CurveTubes, then I bring those CurveTubes into Modo. As they have clean topology I can convert them into curves for use with Modo’s hair system. Each tube gets its own hair material so I can get maximum control over the final look. It’s a relatively straightforward technique but it gives a pretty accurate representation of the sculpt you started with in ZBrush. It means I can avoid grooming tools and that’s…

Massive agents are customisable by the user, which means you can swap out geometry and texture maps and customise models to look any way you like. But the horse and rider agent does offer a variety of texture maps already built-in. “If you’re going to see a thousand or 10,000 horses,” says Stephen Regelous, “you don’t want to go, ‘Oh, those two look the same and they’re right next to each other.’” Massive therefore crafted textures in different colours (such as grey, black, white, brown, reddish) as well as adding in ‘dappled’ patterned versions of those. “The next stage,” adds Regelous, “was creating a procedural shader that actually makes unique dappled horse texture maps on the fly. It basically uses noise to create very realistic-looking patterns of dappled horse textures.…

Your CG problems solved Pietro Chiovaro replies There are a lot of methods you can use to create a realistic roof material, and many of these methods start by the utilisation of the internal textures of the software. However, today I will explain how to create a realistic roof material using some external textures, which you can create starting from a photo or by downloading from a site. Starting from this point, we need to first select the model in which we want to assign the material, then we have to open the Node Editor panel and add these elements: the Texture Coordinate input, two Image Texture nodes, the shader Diffuse BSDF, the Glossy BSDF shader, two Gamma nodes (that we can find in the Color section), the Hue Saturation…

1. When a model gets published in Maya we automatically create a Houdini surface asset, so the shading artist can immediately start creating and assigning materials in Houdini. 2. Materials are assigned as a SOP attribute, where we use procedural wild-card assignment that references material tags predefined in Maya (*metal*,*wood*). Each material can contain an arbitrary number of layered RISE shaders, a heavily customised version of SideFX’s Classic Shader. 3. Before publishing a surface asset, the artist can also assign custom split attributes which will be used to split the asset into several objectlevel nodes for easier separation into different render layers. All this is done in a special HDA (Houdini Digital Asset) we call the ‘asset container.’ This HDA is embedded in the HIP file. When the asset gets…

During the capture process, all the traditional horse moves were envisioned, including rearing and stomping. But Regelous' research into horse behaviour also uncovered some unusual actions that horses are capable of. “For instance,” he says, “there's this bizarre move that I'd never even seen until I started researching, where horses can actually hop on their back legs.” Another move now possible is to have the horse and rider fall realistically, just like an onset horse stunt. “This uses the smart stunts feature in Massive, which uses rich body dynamics. “What you don't want is for the horse to suddenly drop dead and be this floppy bunch of bones that eventually grinds into the ground. What you do want is for something that's still able to move and look like it's…

Just imagine what would happen if an important plot detail was leaked on a film like The Last Jedi in advance. Not only would you potentially ruin the cinema experience of millions of people, your name in the industry would quickly become mud. So as to be expected, security was super-tight on the project, to the extent that Jellyfish Pictures worked off a totally separate network from their regular one, and the internet connection was limited to simply downloading files from ILM and nothing else. “We pretty much work off the grid on all these – and I think that’s the norm these days with any Disney or Marvel show,” says Cheetham. “You have to work in a cut-down, established way that cannot be visible. “You limit mobile phones, you…
