Sets the options when creating a smoke effect. Here are the options:
Identifies the filename (with extension) of the first image of the series to be used for the smoke. To use the default images supplied with Maya, enter the name Smoke.0.
To use files from a directory other than the sourceimages directory in your current project, specify the complete path.
The images must have filenames in the format name.1, name.2, name.3, and so on.
To choose a different filename after you use the Smoke effect, display textures in the Hypershade and double-click the file1 texture to display the Attribute Editor. The Attribute Editor has an attribute named Image Name that specifies the filename and path.
When each particle is emitted, it has an opacity of 0. The opacity gradually increases, hits a peak, then tapers off to 0 again. The Smoke Threshold sets the moment the opacity hits its peak, specified as a fraction of the particle’s lifespan. For example, if Smoke Threshold is 0.25, each particle’s opacity peaks at one-quarter of its lifetime.
