From clay models to PlayStation: how Skullmonkeys was made

Most PlayStation games started inside a computer. Skullmonkeys didn’t. Its characters were sculpted from real clay, moved by hand, photographed frame by frame and then turned into digital graphics for Sony’s original PlayStation. That gave the 1998 platform game a look that was hard to confuse with anything else on the console. At a time when developers were rushing towards polygons and 3D worlds, Skullmonkeys took a very different route. It looked physical because much of it actually was. Behind the game sat a production process built around clay, cameras, stop-motion animation and a lot of patience.

From real clay to PlayStation graphics

Skullmonkeys was developed by The Neverhood, Inc. and released for the PlayStation in 1998. It followed The Neverhood, the studio’s 1996 PC adventure game, and kept the same clay-based visual approach. The gameplay changed completely.

Instead of pointing and clicking through an adventure, players controlled Klaymen in a traditional side-scrolling platform game. You ran through levels, jumped over hazards, collected items and dealt with enemies. Simple enough. The unusual part was how those characters reached the screen.

Artists didn’t just open a 3D modelling program and build Klaymen digitally. They created physical clay models, posed them and photographed the individual stages of their movement. Those photographs could then be processed and turned into animation frames that the PlayStation could display during gameplay. It’s a strange combination when you think about it. Part animation studio, part sculpture workshop, part game developer.

A production process involving tonnes of clay

The wider Neverhood production became famous for the sheer amount of clay involved. More than three tonnes of material were reportedly used while creating its characters, objects and environments. That figure is often associated with the original Neverhood production, which established the physical techniques later carried into Skullmonkeys. The clay wasn’t just there to give artists something to copy. It was the artwork.

Characters had to be sculpted in the real world. Sets and objects could be physically built, changed and photographed. Some designs even started with ordinary objects or toys that were covered in clay and reshaped until they became something completely different.

That physical process left details behind that digital artists would normally have to recreate manually. Tiny dents. Uneven surfaces. Finger marks. Slight differences in shape. They’re all part of the look.

Stop-motion inside a platform game

Animating clay isn’t quick. If Klaymen needed to move, the team had to create the poses needed for that animation. The character could be adjusted slightly, photographed, adjusted again and photographed again. Repeat that enough times and you’ve got movement.

Those images then had to become usable game assets. That’s where the traditional stop-motion process met conventional game development. The finished character still needed to respond immediately when the player pressed a button. Jumps had to feel right. Enemies needed collision detection. Platforms needed predictable boundaries.

The player didn’t need to think about any of that production work. You pressed jump and Klaymen jumped. Behind that simple action, though, sat a visual pipeline that looked very different from the one used by most PlayStation developers.

Familiar platforming with an unusual appearance

Underneath all that clay, Skullmonkeys is a fairly recognisable 2D platformer. Klaymen runs through individual stages, avoids traps, defeats enemies and collects clay balls. There are weapons, temporary abilities, hidden areas and boss fights.

That familiar structure helps. The game doesn’t ask players to learn some strange new control system simply because the graphics were made differently. Its mechanics are easy to understand, while the clay animation gives the game its identity.

The soundtrack also refuses to sound ordinary. Terry Scott Taylor’s music moves between playful, strange and deliberately unexpected ideas, matching the game’s visual style without turning the whole experience into a technical demonstration. It’s still a platform game first.

Why Skullmonkeys still looks different

It’s much easier to create convincing clay digitally now. Modern developers can use detailed 3D models, scanned materials, advanced lighting and realistic surface shaders. A computer can reproduce fingerprints, dents and soft clay textures without anyone touching an actual lump of modelling material.

Skullmonkeys worked backwards from that idea. Instead of asking a computer to imitate clay, the developers used real clay and brought the resulting images into the computer. That’s the important difference.

It explains why the game doesn’t quite look like conventional CGI, traditional hand-drawn animation or normal sprite artwork. The source material came from physical objects sitting in front of a camera. And this all happened during a console generation obsessed with 3D.

Games were showing off polygon counts, rotating cameras and fully three-dimensional environments. Skullmonkeys stayed side-on, kept the platforming familiar and concentrated on a production method almost nobody else was using at that scale. The result is a PlayStation game whose technology is interesting precisely because so much of its artwork began outside the PlayStation. Before Klaymen became pixels on a television, he was clay on a table.
