Finally, we prepare the garments with customised, built-in simulation controls to be used in production. Next, we finesse the movement and material properties by running the garments through various animation cycles and tweaking simulation parameters. First, we design and model the garments onto the character. “At Pixar, we invest the time to set up cloth models before we enter production, a process broken into three equally important steps. The role of the cloth lead is to marry the two. The world we simulate, however, is based on a physics-driven model. However, cartoon animation creates its own problems for the cloth artist, making it vital to establish a good basic workflow, as Pixar’s Claudia Chung explains: “Animation is a world in which strangely proportioned characters move in ways that would never be seen in real life. ANIMATIONīY CLAUDIA CHUNG Our first set of tips relate to a world in which absolute realism is not a priority. No matter what kind of projects you work on, you should find advice here that will help you achieve faster, more controllable simulations. Together, our experts’ tips provide a fascinating, wide-ranging overview of the field. David’s tips explore ways in which artists can ‘cheat’ simulations, or combine them with traditional rigging techniques, to achieve results more quickly. With turnaround times measured in days, it is not always possible to rely solely on simulation. Finally, The Mill’s David Knight discusses the most time-pressured field of all: advertising.

In his tips, cinematics veteran Malcolm Thomas-Gustave sets out measures that artists can take during set-up to minimise problems later on. As the time available in which to fine-tune a shot decreases, the need to produce a simulation that works first time increases. Next, we turn to the high-pressure world of game cinematics. In her tips, The Orphanage’s Daniela Calafatello discusses the importance of getting the fundamental properties of a simulation – such as mesh resolution anbd orientation – correct in order to achieve believable cloth motion. Whereas feature animation is often stylised, visual effects work places greater pressure on artists to achieve photorealistic results.

Accordingly, Pixar cloth lead Claudia Chung focuses on the process of setting up a cloth pipeline, and the way in which complex shots can be broken down into a series of smaller problems that can be resolved completely with simulations. We begin with the market sector in which artists traditionally operate under the least time pressure: feature animation. We asked four experts from different fields within the 3D industry to give us their tips for making better use of these simulation tools. Whereas, a few years ago, it would have been necessary to resort to a third-party plug-in – or to fake the motion of the cloth by hand – most modern 3D packages have sophisticated cloth simulation systems built in as standard.

Our 40 tips, supplied by experts from every sector of the 3D industry, will help you create faster, more controllable clothing simulationsĬlothing simulation has now become a standard part of professional animation jobs. So I am feeling pretty good about it.ĥ) only require baking an ID map, dead easy in SP.Ħ) no special UV cut needed, your uv borders become procedural seams.Forget animating clothes by hand. I compared my solution to the chamfer2.0 node, which operate on the same principle (baking a UV map of some sort) my material works quite well even when working in 1K texture (and texel density here is only 2.56px/cm).

Not happy with the result? Just move a few sliders. We use it to determine UV borders and create procedural seams, for example: The input map is simply a ID map baked in SP, but specially without dilation or diffusion, so basically a map of UV shells. Again, follow the same strategy outlined above, I created a simple edge detection node and use it to blend a few common values, like base color, normal, height, AO etc.
