Recipients of 3D DWF files can view and print them using Autodesk® Design Review, which is an optional part of the 3ds Max install program. For more information about using the viewer, see the Autodesk Design Review help system. Feature Support with 3D DWF Export ■ 2D and 3D splines. The Enable In Viewport setting on the Rendering rollout on page 615 does not need to be enabled in order to export splines. ■ 3D geometry ■ Texture-mapped materials with a diffuse map channel, UV mapping channels, and material IDs NOTE Materials that have Use Real-World Scale on page 5771 enabled display more accurately in the Autodesk Design Review program. ■ Procedural materials, but only as a rough, low-resolution approximation. Real-World Map Size should be off for objects with procedural materials. ■ Materials that have transparency are correctly exported and their opacity values are recognized by the Autodesk Design Review program. Even when you orbit the view, objects that pass behind other objects with transparent materials are still visible. Limitations of 3D DWF Export Materials and Environments ■ Environment backgrounds do not export; the Design Review program uses its own background color setting. ■ Environmental effects such as fog do not export. ■ Materials using reflection maps such as Flat Mirror do not produce reflections when exported. ■ Two-sided materials are not supported. However, you can get around this by turning on Force 2-Sided on the Render Setup dialog. NOTE Turning on Force 2-Sided affects the entire scene. This can slow down the performance of Design Review because it has to process the two-sided display of everything in scene. Exporting 3D DWF Files | 7217
