Gabriel & Karl have been delivering awesome tools to enable fast and easy level design directly in the Unity Editor. With ProBuilder you design, prototype and play test rapidly your levels right in Unity. With Polybrush (beta) you refine your creation by sculpting complex shapes, painting in custom lighting or coloring, and blending textures across meshes.
Starting today the full editions of ProBuilder and Polybrush are becoming part of Unity feature roadmap. They are now available at no additional cost to all Unity subscription plans (Personal, Plus, Pro and Enterprise).
Overview of ProBuilder and Polybrush
ProBuilder is a unique hybrid of 3D modeling and level design tools, optimized for building simple geometry but capable of detailed editing and UV unwrapping as needed.
ProBuilder lets you quickly prototype structures, complex terrain features, vehicles and weapons, or to make custom collision geometry, trigger zones, or nav meshes.
Here are a few key features:
Extrude and Inset
In-scene UV Controls
Indefinitely editable shapes
Probuilder has been used by many games made with Unity, checkout the highlight reel video:
Here's a more extensive but quick overview of ProBuilder features:
There's more... ProGrids gives you both a visual and functional grid, which snaps on all 3 axis. ProGrids enables speed and quality, making level construction incredibly fast, easy, and precise. It is especially handy for modular or tile-based environments, but you will find that it significantly speeds up workflow and increases quality for all types of work.
Combine ProBuilder, Polybrush and ProGrid together, you get a complete in-editor level design solution for faster and more precise geometry construction.
You can of course take advantage of Unity's seamless round tripping with Digital Content Creation tools (like Maya) so you can further detail and polish your models with your favorite tools.
How to get the tools, what's the roadmap
As said in the introduction, starting today these tools are available at no additional cost to all Unity subscription plans (Personal, Plus, Pro and Enterprise). Here's how to get them:
ProBuilder is being integrated in Unity 2018.1 beta and a beta is available today via the new Package Manager. Go to Unity Editor, menu Window>Package Manager, click All, select ProBuilder and click Install:
For Unity 2017.x & 5.6, add ProBuilder to your projects from the Asset Store. The version of ProBuilder from the Asset Store will only receive bug fixes, no new features. All new features will be added to Unity 2018 and forward. Note that support for Unity 5.6 will end in March 2018. If you purchased ProBuilder prior to its transition to Unity, you will notice that the Asset package is now deprecated. You can still access it from your Asset Store library, but this package will no longer receive any updates.
ProGrids is available from Asset Store. We plan to integrate ProGrids features directly in Unity at some point in 2018. If you purchased Progrids prior to its transition to Unity, you will notice that the Asset package is now deprecated. You can still access it from your Asset Store library, but this package will no longer receive any updates.
Other tools ProGroups, QuickDecals, QuickEdit and QuickBrush are being deprecated. If you purchased any of those prior to the transition to Unity, you will notice that the asset package is now deprecated. You can still access it from your Asset Store library, but these package will no longer receive any updates.
