Getting started - Scripting ​

Simplygon will start the optimization once the Simplygon command is executed in combination with a Pipeline object or a Pipeline file-path. Execute either the MEL- or Python version of the script by pressing the double-arrow in the script windows's menu-bar to start the processing, the optimized scene will be returned to Maya automatically once the processing has completed.

MEL script ​

// select objects in scene
select -all;

// create a reduction Pipeline using the SimplygonPipeline command
$reductionPipeline = `SimplygonPipeline -c "ReductionPipeline"`;

// set the reduction Pipeline's triangle ratio to 50%
$bResult = `SimplygonPipeline -ss "ReductionProcessor/ReductionSettings/ReductionTargetTriangleRatio" -v 0.5 $reductionPipeline`;

// execute Simplygon with the given Pipeline
Simplygon -so $reductionPipeline;

// clear all loaded / created Pipelines
SimplygonPipeline -cl;

Python script ​

import maya.cmds as cmds

# select objects in scene
cmds.select(all = True)

# create a reduction Pipeline using the SimplygonPipeline command
reductionPipeline = cmds.SimplygonPipeline(c = 'ReductionPipeline')

# set the reduction Pipeline's triangle ratio to 50%
bResult = cmds.SimplygonPipeline(reductionPipeline, ss = 'ReductionProcessor/ReductionSettings/ReductionTargetTriangleRatio', v = 0.5)

# execute Simplygon with the given Pipeline
cmds.Simplygon(so = reductionPipeline)

# clear all loaded / created Pipelines
cmds.SimplygonPipeline(cl = True)

Accessing Simplygon UI ​

The Simplygon UI exposes a set of functions that can be accessed through script.

Function table:

Script examples:

// load pipeline
SimplygonUI -LoadPipelineFromFile "D:/Pipelines/ReductionPipeline.json";

// save pipeline
SimplygonUI -SavePipelineToFile "D:/Pipelines/ReductionPipeline_Copy.json";

import maya.cmds as cmds

# load pipeline
cmds.SimplygonUI(LoadPipelineFromFile = 'D:/Pipelines/ReductionPipeline.json')

# save pipeline
cmds.SimplygonUI(SavePipelineToFile = 'D:/Pipelines/ReductionPipeline_Copy.json')
