When using the ‘by Class’ option for element grouping in the CINEMA 4D Settings of the Add-on, Openings won’t be exported into separate groups, although holes will appear on walls/slabs in Cinema4D. When using the ‘by Material’ option, only the UV data is being exported, because of the object hierarchy, so this option is recommended to be used only for quick rendering tasks. To avoid this situation, the UV mapping information should be used, which is also exported. When using the ‘by Class’ option for element grouping in the CINEMA 4D Settings of the Add-on, all texture projections are converted during the export, but because of the differences in texture projections algorithms of the two programs, some projections in CINEMA 4D do not get displayed the same as in Archicad. During the export process only the 3D geometry data, materials, lights and the 3D view are being converted. Limitations at exporting Archicad models to CINEMA 4D by saving 3D view and freeform modeling: As UV mapping cannot be used for solid models in Archicad, one should use convertible projections for objects that should take part in solid operations, and for the other situations, one should set the resulted GDL objects’ model behavior parameter to ‘Preserve textures’. Those projections for that it is possible will be converted into the corresponding projections in Archicad, in other cases UV mappings are computed from the projections, and these mappings are used in Archicad. There are differences in the texture projection algorithms of Archicad and CINEMA 4D, and CINEMA 4D also offers more projection methods than Archicad. One should use the default material model for creating materials for conversion. In these cases parameters and parameter categories are used that are not known by the converter, so these settings are ignored, and if there is not any parameter among the material’s settings that could be converted, the whole material conversion is skipped, and no material is assigned to the converted object in Archicad. Beside the default material model structure there is the possibility in CINEMA 4D to create materials based on different lighting model. While in CINEMA 4D textures can be applied to many kinds of settings (like luminance, transparency), Archicad use textures only for determining object colors, so even the bitmap textures are ignored during the conversion when applied to non color material properties. The only textures one can convert are the bitmaps loaded from image files (jpg/png/bmp). These cannot be converted, while these algorithms are not implemented in Archicad. CINEMA 4D also offers textures that are based on singular algorithms that are computed during rendering. Some of these parameters have according material settings with exactly the same functionality in Archicad, some others can be converted, but there are some that cannot be interpreted by the rendering engine of Archicad, these are simply ignored. There are a large number of parameters for setting the materials’ visual behavior when affected by direct or indirect light or like glowing, transparency, etc. CINEMA 4D offers much more material setting possibilities than Archicad does. During the import process only the material and geometry data is being converted. Limitations at importing CINEMA 4D models into Archicad by loading, merging c4d type files and by freeform modeling: This will start the uninstaller, which will remove all Cinema 4D components from your computer. You can also browse to your Archicad 25 folder and execute the uninstaller in the Uninstall.C4D subfolder.īrowse to your Archicad 25 folder and execute the uninstaller in the Uninstall.C4D subfolder. #How to add multiple layers to a vray material cinema 4d free#
