Build worlds from anyone's packs.
Load an environment pack from any vendor, scatter its props across a hillside, sculpt and paint the ground, then export the whole scene as one file. A Mac app for game developers.
Free · Pro makes scenes by the dozen · USD, glTF, FBX and OBJ
Any vendor's packs
Nobody owns the format. One pack on its own is the normal case, and it works well.
Scatter, don't place
Paint trees, rocks and grass across a hillside, then thin them where it matters.
Sculpt and paint ground
Raise, lower, smooth and flatten, then paint the layers that meet where they should.
One file, everything in it
Export a scene as one USDZ with every prop and texture inside. Unity, Unreal and Godot exporters are coming.
Shape the ground, then dress it.
The tools are the ones you already know from every editor, with nothing between you and the hillside you are looking at.
Raise and lower
Push ground up into ridges or pull it down into valleys, with a brush you can feel.
Smooth and flatten
Settle a slope, or level a shelf where a building has to stand.
Paint layers
Grass, dirt, rock and sand, blended where they meet rather than cut against each other.
Scatter
Trees, rocks and undergrowth by the hundred, brushed on with a natural spacing.
Bring packs from anywhere. Take worlds anywhere.
Worldra doesn't care who made your props or how they arrived, and it doesn't hold your world hostage on the way out.
Native to the Mac, and read directly by anything built on Model I/O.
The open interchange format, and increasingly what newer packs ship.
What most environment packs still ship today, props and all.
The old standby, still in plenty of packs, read with its materials.
Free to build. Pro to scale.
Everything you need to build a world is free. Pro is for studios making them by the dozen — the same line Rigkin draws.

Works with Rigkin
Rigkin builds characters from anyone's parts; Worldra builds the world they stand in. Same formats, same scene file, two apps that were made to sit beside each other.
