## Filter Properties

### Scale

Parameter ID: `F3DSIMPORTFILTER_SCALE`

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

- **Import** the numerical value saved in the file is converted to the current Cinema 4D unit. Example: if an X value of 1 is saved in the file and you define Feet, the X value will be converted to 30.48 cm in Cinema 4D (if centimeters are defined by default in Cinema 4D).
- **Export** numerical values are saved in the file. Example: an X value is set to 100 cm in Cinema 4D. If you define Feet for export, the exported file will save a numerical value of 3.281 (1 meter = 3.281 feet).

More information about units and scaling can be found in the [Project Scale](https://help.maxon.net/c4d/en-us/Content/html/DDOC-DOCUMENT_GROUP_PROJECTSETTINGS.html.md) section.

### Adapt Textures

Parameter ID: `F3DSIMPORTFILTER_RENAMETEXTURES`

### Suffix

Parameter ID: `F3DSIMPORTFILTER_TEXTURESUFFIX`

3D Studio does not recognize so many image file formats for textures or similar like Cinema 4D, but primarily uses the TIF image format. If you select this option, all texture endings in the materials are automatically adjusted to the extension you have preset (e.g., **image.jpg** becomes **image.tif**).

However, you still have to convert the texture images separately, which the Image Manager, for example, can do without any problems.
