Here you can define how Cinema 4D textures/materials are projected onto objects upon import. These are the same projection types as with any Texture tag and can be easily modified after import.
This factor can be found at numerous locations throughout Cinema 4D when importing or exporting foreign formats. Therefore, don’t be surprised if the term ,export’ is used if this factor is seen in an import function (this factor is explained as a whole here).
This factor lets you scale files upon import/export, i.e., practically all relevant numerical values saved in the file or those to be saved will be multiplied by this factor and then saved - or interpreted when loaded.
The unit at the right in turn defines how upon
More information about units and scaling can be found in the Project Scale section.
