Clipping geometries

To use a clipping geometry when doing Remeshing two selection sets needs to be created. The first set is the "ProcessSelectionSet" which includes all meshes in the scene that should be processed, the second set is the "ClippingSelectionSet" which includes meshes that should be used as clipping geometries. The clipping selection set will clip everything that intersects with the clipping geometry and remove triangles that are in the negative normal direction of the surface.

Selection sets:

// load a remeshing pipeline
$remeshingPipeline = `SimplygonPipeline -l "D:/Pipelines/remeshingPipelineWithBaking.json"`;

// set the process selection set
$bResult = `SimplygonPipeline -ss "RemeshingProcessor/RemeshingSettings/ProcessSelectionSetName" -v "ProcessSelectionSet" $remeshingPipeline`;

// set the clipping selection set
$bResult = `SimplygonPipeline -ss "RemeshingProcessor/RemeshingSettings/ClippingGeometrySelectionSetName" -v "ClippingSelectionSet" $remeshingPipeline`;

// pass the settings object to the Simplygon command
$bResult = `Simplygon -so $remeshingPipeline`;

// clear all pipelines
SimplygonPipeline -cl;

import maya.cmds as cmds

# load a remeshing pipeline
remeshingPipeline = cmds.SimplygonPipeline(l = 'D:/Pipelines/remeshingPipelineWithBaking.json')

# set the process selection set
bResult = cmds.SimplygonPipeline(remeshingPipeline, ss = 'RemeshingProcessor/RemeshingSettings/ProcessSelectionSetName', v = 'ProcessSelectionSet')

# set the clipping selection set
bResult = cmds.SimplygonPipeline(remeshingPipeline, ss = 'RemeshingProcessor/RemeshingSettings/ClippingGeometrySelectionSetName', v = 'ClippingSelectionSet')

# pass the settings object to the Simplygon command
bResult = cmds.Simplygon(so = remeshingPipeline)

# clear all pipelines
cmds.SimplygonPipeline(cl = True)

Resulting mesh:
