Prototype rapidly

Build basic or advanced geometry, right in Unity, with zero creative barriers. Devs agree, ProBuilder is wicked fast and incredibly easy to use- even Collision and UVs are automatically generated. Just build, and have fun!

Play instantly

Playtest at any time, then edit immediately, and never leave Unity. No time (or sanity) wasted.

Perfect easily

Go advanced with complete UV unwrapping, advanced lightmap settings, optimization, and more. Or, export your models to OBJ and detail externally!

Fundamentals of Using ProBuilder

ProBuilder 101: Object Mode vs Element Mode; basic Vertex, Edge, and Face editing

Object vs Element Mode

Object Mode and Element Mode are the foundations of ProBuilder.

In Object Mode, the ProBuilder object behaves like any other Unity game object, for the most part.

In Element Mode, you can edit the individual Elements (Vertex, Edge, and Face) that compose the object’s geometry, as well as UVs and per-face textures. To begin editing an Element, simply click on it’s icon in the GUI. Clicking again on an active Element icon will return to Object Mode.

Selecting Elements

Selecting Elements is exactly the same as selecting standard Unity objects. You can click on a single Element to select it, or shift-click to add/remove from selection. Drag-select multiple Elements at once, or hold shift to add/remove from selection.

Bonus: Clicking on any face will automatically select all it’s Elements! You can also hold “shift” to add/remove the Elements to the selection.

Manipulating Elements

Manipulating Elements is done with standard Unity controls, nothing new to learn here! We take pride in keeping ProBuilder simple and intuitive for all Unity users.

Simply choose the Rotate, Scale, or Move tool from Unity’s toolbar, select the Elements to manipulate, and have fun!

Basic vs Advanced

ProBuilder Basic includes the core, essential features of ProBuilder. Great for rapid prototyping and basic usage.

ProBuilder Advanced adds support for subdivision, edge-loop modeling, manual UV unwrapping, optimization, and many more advanced features. Also, a great way to say “thanks”, and support continued development of ProBuilder!

FAQ

Can I use ProBuilder Basic commercially? Yes! There are zero usage restrictions for either version. Indie or pro, personal or commercial, we are simply happy to know our tools  have helped your development!

Can I upgrade from Basic to Advanced? Of course- just purchase ProBuilder Advanced, and perform a standard install, the same as you would if upgrading to a new version. All your models, UVs, textures, etc, will remain the same.

Notable Features and Functions

These are just a few of ProBuilder’s features- see the Documentation for a full list + details

General Features

UV Editing + Texturing

Geometry/3D Modeling

“Smart” GUI   ProBuilder’s GUI dynamically adapts to your Element Mode and selection. This way, all possible functions are always available, but only when you need them, retaining a sleek and slim GUI.
Fast, Powerful Texturing   Use standard drag-and-drop, “QuickPaint”, or the keyboard-enabled Material Palette to quickly apply materials to individual faces or entire objects. ProBuilder automatically optimizes and tracks sub-meshes and UVs.
Extrude   One of ProBuilders best features- select any face or open edge, and simply hold shift while Moving, Rotating, or Scaling to extrude. You can even extrude multiple faces/edges at once!
Vertex Coloring   Use the Vertex Colors feature to quickly apply overlay colors to individual faces- especially great for early map testing, and designating team areas.
Automatic UVs   By default, ProBuilder automatically tracks and updates UVs so you can build distraction-free. Auto-UVs also allow control of Rotation, Tiling, Offset, Fit Method, and more.
Subdivide   Quickly add detail to meshes using Subdivide- each selected face will be divided into four new faces, resulting in 4x polygon resolution. Can also be applied to an entire object at once.
Merge Objects   Select any number of ProBuilder Objects, and click Merge to collapse them into a single mesh. Great for saving drawcalls, and you can always detach sections later, by using the “Detach” action.
Manual UV Editing   New in v2.3, ProBuilder features a complete UV Editor window, for manual unwrapping and fine-grained control. Includes projection modes, UV welding, seam control, element pivots, and much more.
Edge Loop Modeling   ProBuilder is also geared for the powerful “Edge Loop Modeling” workflow, with Loop, Ring, Insert Loop, Connect, Edge Extrusion, and many more edge-focused features. “Edge Loop Modeling” is ideal for fast construction and clean geometry.
Trigger and Collision Types   Build a shape, then use ProBuilder to mark it as a “Collision” or “Trigger” type- ProBuilder automatically sets all the right flags, applies a special material, and stores it’s “Entity Type”. Collision and Trigger types can be globally toggled on/off with a single button, and will always automatically hide when the game starts.
In-Scene UV Control   For quick, intuitive control of UVs, you can Move, Rotate, or Scale right on the object- there’s no simpler method!
Smoothing   Set both Smooth and Hard face groups with the Smoothing control panel- giving you complete control to force sharp edges or smoothed contours, exactly as you need.
OBJ Export + ProBuilderize   At any time, you can export your ProBuilder geometry to OBJ format, for modification in an external 3D program or just to save. Inversely, you can even “ProBuilderize” imported models to make them editable with ProBuilder!
“Auto-Stitch” UV Editing   We are very proud of developing this one- a unique blend of manual UVs and auto-layout. Select a face, hold CTRL, and click through adjacent faces to automatically unwrap and stitch. Incredibly fast and precise!
Detach, Delete, Bridge   Select faces and hit “Backspace” to Delete them. Or, simply Detach faces using the GUI button. If you need to repair, or just fill in gaps, Bridge will connect between selected edges.
Set Pivot Location   Exact pivot location is important, and ProBuilder gives you full control. Use “Set Pivot” to push an object’s pivot to any Vertex, Edge, or Face position, or to the center of multiple elements.
Material Palette   Use the Material Palette to quickly apply materials, without needing to sort through your project every time. You can also pick from the scene, “QuickPaint” (right-click to apply), and use keyboard shortcuts to apply materials.
Grow, Shrink, Invert Selection   Selecting the right elements can be a PITA- ProBuilder has options to help. Use the Grow Selection (with option to Grow by Angle!), Shrink Selection, and Invert Selection tools to save time and limit tedious clicking.
Procedural Shapes   Choose a Shape to start with, then set many unique parameters, such as Height, Width, Depth, Number of Cuts, and more. Example include: Cone, Arch, Pipe, Stairway, Door, Cylinder, Sprite, and many more.
Seamless UV & Geometry Editing With ProBuilder, you are never restricted to just UV or Geometry editing- seamlessly work with both at once, for an even faster, more intuitive workflow than ever.
Weld, Collapse, & Split Vertices   Vertices can be welded together within a custom range, collapsed down to a single vertex regardless of distance, or split apart per-edge, for complete geometry control.
…and much, much more! ProBuilder includes too many features to list here. View the Documentation for complete info!
