Retopo Workspace
Quick Start UV Layout Tools

All tools and functions for creating and changing topologies can be found in the Retopo Room.

Whether you are fine tuning topology created automatically with 3DCoat’s Auto Retopo routines, creating your model topology from scratch, or adjusting and refining topology started in an external application, Retopo Room has what you need.

Each VoxTree object can be edited separately from the Retopo Object Panel (on version 2021, Retopo Groups was renamed to Poly Groups). These can be created automatically or manually if you isolate different areas of your model for different purposes and topology layouts

Every Voxel Layer can be worked on separately via the Poly Groups Panel. These can be created automatically, (when Auto Retopo is used), or manually as you isolate different areas of your model for different purposes and topology layouts.

Compared to the Sculpt Room the Retopo Room is quite easy to digest having merely 4 main areas to learn and use:

  1. Tool Panel where you find all of the tools for creating and adjusting topology, as well as the tools for creating UV seams and unwrapping your topology for further modification in the “UV Room”.
  2. Poly Groups Panel where you can isolate all of the areas and parts of your model that need specific topology and texturing.
  3. UV Preview Panel which does just what it says, displays a preview of your UV map. Don’t mistake this for an area to edit UV’s this is done in the “UV Room” after a model has been “Baked” into the “Paint Room”.
  4. The Retopo Menu - which makes available all of the “Import/Export” functions, “Baking” options as well as “Saving” and “Restoring” of your specific Retopolgy work.

Make sure that you also pay close attention to the Options that present themselves in both the “Tool Panel” and the Retopo Top Bar Tool Parameters Panel (the top, horizontal panel below the “Menu” area). The settings that are available for each type of work you are performing automatically change in both Panels.

The Retopo Tools allow you to construct totally new topology by means of working with individual polygonal vertices, polygon edges, polygon faces and polygon “strips” (rows of connected, polygons).

All created topology can automatically be set to “Snap” to the nearest Model surface. Entire loop networks can be created instantly by using a combination of Through Strokes and Freehand Strokes.

“Circular Loop Arrays” can also be made with a minimum of effort, by means of Freehand Strokes as well.
The beginnings of true Polygonal Modeling are also beginning to appear, function by function, within the confines of the Retopo Room.

New Extrude and Bevel functions allow you to extrude and bevel both edges and faces of your topology letting you add all new volume and detail to your original or imported models.

- Added a Script command generator in the primitive tool, Sculpt, and Retopo rooms. You can save your actions in a script file, change your primitive parameters in the script and run it again.

- Added the support of Modeling and Retopo primitives via Scripts. You can use the retopo classes for creating the primitives in the Retopo and Modeling room via scripts.

- Added the new tools for creating 2D primitives for Modeling and Retopo rooms. You can create the 2D primitives (circle, box, plane, ellipse, N-gon, disk, triangle).

- Added the Record Script button in the top menu. The button changes the color depending on the record state. If the button is red then the script is recording, the blue button indicates that the recording is stopped.

- Added the boolean operations for retopo primitives in Retopo and Modeling room. You can create primitives using the boolean operations add, subtract, intersect, split.

- UV Preview

This revised and improved Automatic Topology Creation function now produces very accurate, contour following topology automatically, that works equally well for both organic and mechanical shapes.
Auto Retopo

3DCoat provides a plethora of tools for constructing custom topology, automating repetitive tasks when possible giving you the speed you need to get your project done on time.
Manual Retopo

3DCoat has a Layer system for retopologizing meshes. This makes it easier to retopologize your meshes with problem areas and to have multiple retopology versions of the same object.

Much like all the other Layer tabs in 3DCoat, they function like the Layers in Photoshop. You can click and drag Layers to reorder them, drag them to the Trash icon to delete them, hide & show them with the Visibility icon, etc.

Retopo Workspace: This video begins a series providing an overview of the most commonly used Retopo Tools, in 3DCoat, starting with the Manual Retopology tools.

Quick Start: UV Brush Mode: This video demonstrates the usage of the Brush Mode when editing UV's in 3DCoat. It enables the user to re-shape, tweak, or relax UV islands/shells in a freeform fashion.
