Have a look at a Unity extension called UModeler which lets users model and prototype easily and quickly without leaving Unity. Using UModeler users can craft a static mesh asset as well as prototype a game level without any other external DCC tools.
What is more, the developer states that UModeler supports not only modeling with gizmos but also sketch-based modeling which lets users draw a 2D shape on a surface and make it 3D shape in intuitive ways. “Any polygon is automatically triangulated to be fed to a rendering pipeline even though it has holes inside which will save a lot of your time. UModeler consists of about 90 tools for modeling and UV Mapping, which will make creating, transforming and editing your model a breeze in Unity.”
- Modeling with Gizmos
With the Move, Rotation and Scale gizmos you can move, rotate and scale vertices, edges and polygons with easy.
And holding SHIFT and moving those gizmos allow you to extrude elements.
- Smart Push and Pull
With the Push/Pull tool, you can create a 3D shape from a polygon or cut a 3D shape out of your model. It let you push/pull any type of polygon.
- Curved Shape Modeling
UModeler provides several ways of creating curved shapes. Bevel and Follow tools allow you to create chamfered or rounded corners to geometry quickly. With the Arc and disk tools you can draw curves everywhere and make them 3D easily with Push/Pull tool.
- Synchronous Mirroring
Mirroring an Object will create a reversed version of it. In Mirror Mode any changes you make are reflected immediately to the reversed part.
- Geometry Cutting
With the various drawing tools you can cut up a polygon or create a hole. Loop Slice tool allows you to subdivide polygons using edge loops. And Cut tool enables you to cut up a mesh into two along a line as if it is done by a knife.
- Boolean Operations
Union, Intersection and Subtraction between two UModeler objects can be applied and it usually makes a clean geometry.
- Extruding along a Path
Follow tool leads a polygon along a path to create a 3D shape. It has a multitude of applications and enables you to draw complex 3D models with only a few clicks.
- Easy Mesh Repair
Collapse Tool, Remove Double Tool, Bridge Tool, Eraser Tool, Combine Tool, Align Tool etc. There are many tools in UModeler to help you repair a mesh to make it clean.
- Parameter Based Shapes
Any primitive shapes can be created by dragging a mouse and you can fill parameters with specific numbers in the inspector to give them detailed changes.
- Simple Polygon based Topology
Any 2D shape can be a polygon in UModeler. Concave as well as convex shape is a basic manipulation unit. Even a polygon with holes can be handled with no difficulties. This is because UModeler can triangulate any simple polygons to feed them into the renderer.
- Sketch based Modeling
With the support of the simple polygon topology you can sketch and draw a polygon. This reduces the difficulties of modeling a lot. Therefore modeling novices can model what they want easily as well with UModeler
- Smart Cursor Snap
When the cursor is hovering over a point, a line or the midpoint of a line and polygon etc, it will be snapped to them immediately and the color of the cursor will change accordingly. For example the cursor color will change to orange when it is snapped to a point and it will be a green when it is snapped to a line. Moreover UModeler will tell you that the line you are drawing is whether it is parallel with one of the main axes or it is snapped to a principal axis-aligned line crossing a point with different cursor colors.
- Various 2D Primitive Shapes
Line, Arc, Rectangle, Rounded Rectangle, Disk, Side Stair and Parallel Line tools are provided to allow you to sketch on a polygon and floor. With the combination of these 2D shapes you can create a variety of polygon shapes intuitively.
- Sketch and Extrude
The powerful and easy-to-use drawing tools allow you to sketch a plan of your level and the Push/Pull tool makes it 3D by just dragging a mouse. The way of creating the 3D primitive shapes provided by UModeler enables you to add boxes, cylinders, stairs, cones, spheres etc to any place easily.
- Beyond Just White Boxes
The various modeling/UV Mapping tools will give you chances to enhance your prototype level consisting of just white boxes to a elaborate level with no help of the external DCC tools.
- Immediate Mesh Editing
A mesh with MeshFilter component can be modified and edited just by adding the UModeler component. It’s called UModelerization.
- No more Export & Import
You don’t need to export a mesh out of Unity and import it into other DCC tools to modify a mesh because UModeler empowers you to convert a general mesh and modify it without leaving Unity.
- Built-In UVEditor
UModeler has a built-in UV Editor which consists of a viewport, toolbar and menu panel. You can move, rotate and scale every UV, edge, face and UV island with the gizmos easily.
- 90 degree rotation tools
- Alignment Tools
- Flip Tools
- And More
- Export UV Outlines
The UV outlines can be exported to .png file to be used with texture map painting, atlasing, sprite sheets, etc.
- Weld and Sew
You can collapse the selected elements to the first, center or last with the Weld tools. With the Sew and Move-Sew tools you can join the UVs corresponding to the same vertex in 3D space with ease.
- Pivot Point Control
Using Cross Cursor you can set a spot about which a rotation takes place, or to and from which a scale occurs
