Kitbash

The Kitbash Room is a dedicated workspace for assembling scenes and detailing hard-surface models using a library of pre-made 3D parts, known as kitbash (or Greebles) parts.
This feature streamlines the process of rapidly blocking out or refining concepts like vehicles, machinery, and architecture.

How the Kitbash Room works: the Kitbash Room in 3DCoat streamlines the process with specialized tools and features.

• Asset library: You can import and organize your own pre-made 3D models (OBJ files) into a visual library. 3DCoat automatically generates thumbnails for easy browsing.
• Rapid placement: You can quickly add, move, rotate, and scale these kitbash pieces onto your primary model. This feature is particularly useful for adding complex geometric details, or “greebles,” to your surfaces.
• Negative volumes: For more advanced detailing, you can use “subtract mode” on Tool Options before applying it.
• Voxel integration: Because 3DCoat’s sculpting has a voxel-based mode, you can merge kitbash parts directly into your main model without worrying about topological issues.

How to use the Kitbash Room

---

1. Access the room: Switch to the Kitbash Room in 3DCoat.
2. Import your assets: Import your .OBJ kitbash parts to Sculpt Models, Joints or Splines Panels.
3. Place parts on your model: Select and place parts, using gizmos for transformation.
4. Use negative volumes (advanced): Prepare negative volume versions of parts (e.g., _negative in filename).
5. Merge into voxels: Merge placed parts into your main sculpt.

Primitives Library from Tinker

Joints

---

It is a set of various parts that can be attached and linked with each other, like ‘lego’.

Splines

---

Library of Splines: Splines is a set of flexible objects that can be stretched with the Curves or Snake tool:

Joint Specifications

---

There are two ways to make elementary bricks for the Joints tool.

– Make joints in 3D-Coat. Read this document.
– Make joints in some external editors. Read the specifications.

Technical requirements for models with Joints

---

The model should be created taking into account the scale of the grid. For example, if it is a cube, then 10*10*10, a brick – 20*10*10.

The blocks could be larger. However, they should be made to apply neatly onto the grid of 10*10*10. 
The vertical axis is Y. If the model is a tube, the diameter should be five if the tube’s corner, any parameter taking into account the corner is applied to the tube of 5 in diameter. 

You may add joints to the model right in 3DCoat. For this purpose, please make the model in the retopo room (sculpt and retopo or model in the retopo room from scratch).
Then go to Retopo room->Make joints and add as many joints as you need.

It looks like this:

Press Add joint to add a new joint. There are several options for each joint – axial symmetry, vertical/horizontal alignment, and compatibility with other joints.

Please fill in the name of the model and press Publish as soon as the model with joints is ready. The model will be placed in the Joints palette, and you will get to the Joints tool to test the model with joints. Pay attention that the model with the same name will be overwritten.

Model requirements.

The models are low-poly ones – up to 5К polygons per model. If there is a tube designed – 16 segments should be created. 
A model could be a composite one. If there is a sub-object (retopo group) with the name of Shader_Gold, there will be created a volume named Shader_Gold, where the subobjects of this type will be gathered. That volume will be assigned a shader whose name fits best with the word Gold.
