BUILD YOUR WORKFLOW

From the ground up.

Choose the part you want to work on next. Each module gives you a different way into your world.

Clipmap in preview

Terrain

Use Unity terrain with Gaia, or try Storm’s clipmap terrain preview.

Biomes

Scatter prefabs deterministically at design time or runtime, with variation and avoidance rules.

Building Generator

Create interiors and exteriors from modular packs; output prefabs or Storm instances.

Area Populator

Dress rooms and outdoor spaces using rules, volumes and anchors.

Painter

Paint masks, place objects along splines, and adjust procedural results by hand.

Geospatial

Bring mapping data and GeoTIFF heightmaps into game landscapes. Not a survey-grade digital twin.

FROM OPEN LAND TO SOMEWHERE TO BELONG

Give your world a story.

A house at the edge of the woods. A road that disappears into the distance. What will someone find in the world you make?

BEFORE YOU BEGIN

A few useful answers.

Can I bring an existing project?

Storm can adopt existing scene vegetation and props.

What happens if my subscription ends?

Editor access under a subscription ends when the subscription expires. Built games continue to run without checking the license status.

What comes with Storm?

The World Building Bundle adds Gaia Pro VS, GeNa Pro, GTS, Ambient Sounds and Pegasus, alongside terrain stamps and other tools. Review the current package details in the official store.
