Epic Games Unreal Datasmith (UDATASMITH) Writer Parameters

Choose a name for the .udatasmith file within the dataset directory.

If this parameter is left empty, the default name is always scene.udatasmith.

• Yes – Coordinates of all the points in the written features will be offset so they are centered on origin (0,0,0) and scaled to 1 Unreal Unit per centimeter.

Additionally, the transformation matrix required to scale the model back to world coordinates will be written to a companion .fwt file. This can be used to improve precision of the written coordinates. The companion .fwt file will have the same name as the primary data file and will be written in the same folder. For folder-based formats, the file global.fwt will be written instead.

• No – The original coordinates will be written as provided. Coordinates will not be projected; .fwt world and .prj files will not be generated.
• Transform Coordinates Only – Transforms the coordinates as in the Yes option, but companion .prj and .fwt world files will not be generated.

Some files contain ambient or emissive colors. These colors can, in some cases, cause unwanted visual artifacts to appear on the output .udatasmith file.

• Ignore Ambient Color – When set to Yes, Ambient Color will be excluded from materials. The default is No.

• Ignore Emissive Color – When set to Yes, Emissive Color will be excluded from materials. The default is No.
