Save a Shader Preset

Below is an example demonstrating how you can use script accessible settings to control the saving of a Shader Preset..., without causing the output options or file save dialogs to be displayed.

• DzApp
• DzAssetIOMgr
• DzFileIO
  • DzAssetIOFilter
• DzSettings
  • DzFileIOSettings
• DzScene
• DzNode
  • DzSkeleton
  • DzBone
• DzMessageBox
• Array
• String
• Number
• Global
• QObject

Click the name of the example below to save it as a file.
