Unity probuilder

3D Modeling in the Unity Editor

By Alejandro Romero

Description

ProBuilder is a Unity extension that allows users to natively edit 3D models in the Unity editor, instead of importing a model from another program. This extension works seamlessly with the ProGrids and Polybrush Unity extensions, which allow for object snapping along a grid and surface sculpting, respectively.

Metrics

Accessibility: How user-friendly is the software?

  • ProBuilder is now built into Unity, so access once in Unity is very simple

  • Flexible options allow for workflow customization

Power: The engine's power - i.e. how much one can do with this

  • Surprisingly deep editing capabilities directly in game engine

  • Does not support sculpting, painting, or snapping into positions (solved with additional extensions, namely ProGrids and Polybrush)

Usage: Evaluation of software's effectiveness in certain use cases

  • Save time by editing basic geometry directly in Unity rather than other software
