DirectX X File Writer Parameters

File Settings

  • Text: Produces a human-readable text file that can be examined using a text editor.
  • Binary: Produces a binary version of the file in the legacy binary format, which is generally smaller than the text version.
  • Compressed: Produces a compressed version of the file.

Coordinate System

DirectX uses a left-handed coordinate system (LHCS), while FME natively uses a right-handed coordinate system (RHCS).

During export, FME features will be transformed to convert to a LHCS according to the option selected on the writer.

  • Flip Z: FME will convert to LHCS by scaling all z-values by negative one (-1).
  • Swap Y and Z: FME will convert to LHCS by swapping the Y and Z axes.

Textures

Preferred Texture Format

Specifies the preferred format for associated texture files. This preference will be used as long as the specified format supports the properties of the texture raster; if not, it will be overridden.

In the default Auto mode, the writer chooses the best representation based on the incoming texture raster.

If the preferred format is ignored, a message is added to the log file. Possible reasons that the preference will be ignored include a lack of raster palette support, alpha channel support, or color depth support in the selected format.
