modo203相比202主要在UVs贴图工具方面进行了增强增加了不少新的贴图工具，在渲染方面也进行了不少优化，无论是全局光或是光线追踪的速度都比过去有所提高。同时此版本还增加了对DXF格式的支持，允许直接输入输出2D、3D格式的DXF文件。
New and improved features in modo 203
modo 203 includes technology and user interface additions that combine to make the rapid development of high-quality UVs even easier. The UV unwrap tool has been improved so that UVs are laid out by the software with less angular and proportional distortion as compared to the geometric polygon volume. To help modo users interactively relax the UV data, the UV pinning function has been improved. The seal hole option in UV unwrap has also been overhauled for more reliability on enclosed spaces in the mesh, such as eye sockets. UV editing is also improved through the addition of a move and sew option – an enhancement to the previous sew capability that makes the joining and scaling of discontinuous UVs a one-step operation. Copying and pasting a UV between polygons is now facilitated in modo, and a new UV orient capability makes it very easy to have all UVs perfectly lined up horizontally or vertically.
The modo renderer - already one of the industry’s fastest renderers for global illumination - gets two additional speed injections in modo 203. The fundamental operation of ray tracing has been boosted as much as 1.4 times in tests conducted by Luxology and even greater speed has been reported by beta testers. In addition to faster production rendering, ambient occlusion and full light “baking” operations (often employed to further accelerate rendering in game development and many other fields) also benefit from the ray-tracing speed improvement. Irradiance caching has been optimized, further cranking up global illumination performance on large resolution renderings.
modo 203 also features a new DXF plug-in that reads and writes ASCII DXF files from inside modo. Architects and designers can now use modo to import a range of 2D and 3D entities from DXF files; including: polymesh, arcs, circles, lines, points, polylines and more. Layers in the incoming DXF files are automatically created as corresponding layers in the modo scene to preserve file organization. On export from modo, the new translator converts modo triangles and quads into a polymesh, with vertex connectivity maintained. This further extends modo’s pipeline integration capabilities, allowing it to be used in partnership with many design software tools that also support DXF.
