When VoxiGen is the better pick
- You want to start free, in a browser, before paying for anything.
- You build whole levels, not only single assets, and want them in Godot.
- You want characters rigged and animated inside the editor.
- You want AI to block out models and characters for you to finish.
When Qubicle is the better pick

- You want a mature desktop tool for characters split into parts.
- You work offline on a desktop.
Questions
Can VoxiGen open Qubicle files?
Not .qb files directly. Export the model from Qubicle as .vox and open that in VoxiGen.
Is there a free alternative to Qubicle?
VoxiGen's editor is free in the browser with no account. Mesh and level export for game engines, with commercial use, come with the Founder licence, $29.99 once.
Does VoxiGen work for game characters?
Yes. Character mode rigs a model on a skeleton and plays animations such as idle, walk, run and attack, and Build can make a rigged character from a description.
