Create a Variant Set¶
If this is your first time authoring a variant set, we recommend that you follow Authoring Variants USD tutorial first.
A Variant Set is a composition arc that serves as a sort of “switchable Reference” allowing you to provide alternate property opinions or entire prim hierarchies. In this snippet, you’ll find how to create a Variant Set, add variants to the new Variant Set and author opinions for each variant.
# Create the variant set and add your variants to it. variants = ["red", "blue", "green"] shading_varset = prim.GetVariantSets().AddVariantSet("shading") for variant_name in variants: shading_varset.AddVariant(variant_name) # Author opinions in for each variant. You could do this in the previous for loop too. for variant_name in variants: # You must select a variant to author opinion for it. shading_varset.SetVariantSelection(variant_name) with shading_varset.GetVariantEditContext(): # Specs authored within this context are authored just for the variant. ... # Remember to set the variant you want selected once you're done authoring. shading_varset.SetVariantSelection(variants)
