Microsoft DirectX File Writer Parameters

• 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.

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.

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.

Possible values are:

• Auto (default) – The writer chooses the best representation based on the incoming texture raster.
• PNG
• BMP
• JPEG

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.
