The Previz Sandbox is a brand new live editor for testing, tweaking and presenting your WebGL scenes. The sandbox is an easy way to get to grips with the Previz editor.

The drag and drop interface has been designed so that you can quickly see how your 3D file will render in Previz.

There's no account required to get started with the Previz Sandbox and it supports the following features:

Physically based rendering

Physically based rendering (PBR) refers to the concept of using realistic shading/lighting models along with measured surface values to accurately represent real-world materials.

The Previz Sandbox supports this workflow including the following attributes: Base color, Metalness, Specularity, Roughness/Glossiness, Normal/Bump, Ambient occlusion, Transparency, Emission, and Face culling.

Dynamic Lighting

Realistic lighting is an essential aspect of 3D design. A well lit project significantly enhances the atmosphere of your scene.

Previz supports both image-based lighting as well as dynamic lights (Directional, hemispheric, point or spot lights). These can be configured and edited directly in the sandbox.


Add movement to your 3d scenes including props, screens and characters. Previz supports animations in the glTF format including multiple animations per file.

The viewer supports the following types of animation: Keyframe (translation, rotation, scale), Shape keys and Armatures / skinning.

Share Preview Links

Share your Previz scenes conveniently with team members and clients. Obtain precise feedback and faster approval via secure, password protected links.

Our recommended file format is .glb. This relatively new file format has quickly become the standard to support 3d scenes in a web browser. glb/glTF minimizes both the size of 3D assets, and the runtime processing needed to unpack and use those assets. It also supports PBR based materials as well as animations which opens up a lot of opportunities for use in our viewer. Going forward all scenes will utilise this modern format. Most 3D software will support exporting this format.

Getting Started

To begin all you need is a glTF file exported as a .glb (binary). Most common 3D applications can export glTF files. Check out our documentation for export settings. Then visit the sandbox and drag and drop your glTF file into the browser window. We also support a variety of other formats as well including .fbx, .obj, .ply.

The sandbox is completely free to use and no account is necessary.

Let us know what you think. We are excited to see what you create.
