Simple Remeshing pipeline (legacy remesher)

This example shows how to create a new RemeshingLegacyPipeline and how to set basic parameters for Remeshing and material baking.

-- create a Remeshing Pipeline object
remeshingPipeline = sgsdk_CreatePipeline "RemeshingLegacyPipeline"

-- set DefaultTangentCalculatorType to Autodesk3dsMax (1)
bResult = sgsdk_SetSetting remeshingPipeline "GlobalSettings/DefaultTangentCalculatorType" 1

print ("DefaultTangentCalculatorType: " + defaultTangentCalculatorType as string + "\n")

-- set the OnScreenSize for the generated mesh

onScreenSize = sgsdk_GetSetting remeshingPipeline "RemeshingLegacyProcessor/RemeshingLegacySettings/OnScreenSize"
print ("OnScreenSize: " + onScreenSize as string + "\n")

-- set the merge distance for the Remeshing processor,
-- a lower value might be preferred for skinned assets to avoid small gaps to merge,
-- or when you want to preserve details (at a cost of triangles).

-- more settings can be set for the Remeshing pipeline,
-- see Pipeline documentation and/or inspect the generated file
-- that is saved out by this script!

-- if material baking is enabled Simplygon will generate
-- a new material (with textures) for the generated mesh.
