它专注于游戏模型的细节设计，集三维模型实时纹理绘制和细节雕刻功能为一身，加速细节设计流程，在更短的时间内创造出更多的价值。只需导入一个低精度模型，3D-Brush 便可为其自动创建 UV，一次绘制，法线贴图、置换贴图、颜色贴图、透明贴图、高光贴图就同时生成了。最大材质输出支持到 4096*4096。真正的无缝材质输出。

最新的 3D-COAT 不但可以进行前面说的细节雕刻和各种贴图绘制，还增加了拓扑功能，体积雕塑功能，硬件渲染功能等等，由于软件的更新速度实在太快，以至于我们目前还不能说3D-COAT 最后会发展成为一款什么样的数字雕塑软件。

3D-Coat 的绘制同样可以设置图层。而且，图层的功能还相当的强大，有多个图层的混合参数以及图层的效果参数。从图层功能上来讲，相比 Mudbox 和 ZBrush，3D-Coat 做的最好，提供了更多更方便的调节方法。

3D-Coat 的扩展功能中最有特色的是拓扑功能，它的拓扑非常的方便，与 ZBrush 那种老老实实的四个点一个面的拓扑不同。3D-Coat 的拓扑支持多种方式。另外 3D-Coat 的 UV 展开功能也很不错，虽然比不上专门的展UV软件那么方便，但是和 ZBrush 相比那已经是很大的区别。至于 Mudbox，只有一个查看 UV 的窗口而无法进行 UV 的编辑。

3D-Coat 4.0的新特点包括以下几个方面：

3D-Coat 4.0提供了全新的用户界面，菜单可以“进行拖拽”可以直接在体素模型上绘图

LiveClay工具可以使sculpting工具实时抽取出多个多边形模型

3D-Coat 4.0提供了全新的拓扑工具，例如Extrude，在拓扑空间内对多边形模型进行完善等

3D-Coat 4.0增添了新的工具，可以在网格中创建或者闭合较大的网孔

图层重影功能

可以输出Collada (DAE)格式的文件。

3D-Coat is the one application that has all the tools you need to take your 3D idea from a block of digital clay all the way to a production ready, fully textured organic or hard surface model.

Beta versions contain bugfixes and features for upcoming V4. Beta features intended for V4 may be enabled or disabled via Edit->references->Show beta tools. Pay attention that versions from 3.7.14 it are actually V4 betas and many features that you see there are actually V4 preview. Beta features are LC tools, iconic UI, colored specular/emissive, scaled projection for photoshop, some new retopo tools, vertex voxel painting and some other, you may check it with "Show beta tools". But actually it hard to distinguish what beloongs to V3 and what to V4 because V4 is just logical evolution of V3.

Changes:

19.02.2013 BETA12

- Main intension of the build is bugfixing, big amount of mantis reported problems fixed. A lot of critical problems solved. Often mentioned lags problem fixed too.

- camera position will be stored in save file, it is convenient to open file and occur in last saved camera state.

- Important change in masks painting - there is volume preserving mode that is now default. In this mode instead of just modulating effects by mask surface may be displaced in both sides - back and forward so that in average volume will be approximately preserved. It is very important if you use mask for detailing. This mode allows to avoid constant surface growing when painting.

- Models palette is now available in Retopo room to be merged directly in retopo room. Retopo layers may be dragged to that palette.

- E-mode circle/lasso/rectangle/spline etc will work closer to PS style - SPACE + LMB will move whole shape.

- Render room got improvement - prossibility to render blended states between several saved scenes. In so way short animated illustrations may be easily rendered. It was done mainly for my son's personal project, I think it will be helpful for community too. I expect to be criticized for this little animation support, but it was my personal needs, not just new feature, so I will be really sad in case of critics.

- a lot of small but important changes that I forgot to mention because stopped to tweet last couple of weeks. Seems should start it again.
