Previz shape 01 texture 01


Physical based materials

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 viewer 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 as 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.

Frequently asked questions

No. The sandbox is completely free to use.

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.

Previz scenes can be shared once you create an account. When you create and publish your scene, Previz will auto-generate a unique URL for you to send to your team, or clients. Links can also be shared securely with password protection.


"Previz helped dramatically when we had to present work in progress to our client. It was also critical for understanding how the content worked at a large scale both in terms of speed and relative size."

"Previz is an extremely useful app. Especially for checking camera angles with the presenter and backdrop, and coordinating/storyboarding graphic content."
