I'm wondering if there's a way to duplicate a Render Var prim with python. I've found I can create a new prim with the DefinePrim() function, but if I do that I'm going to need to loop through all of the Attributes on my existing Render Var and copy them one by one to the new prim. Ideally I'm looking for a DuplicatePrim() option. Does it exist?
Cheers,
Tony

if anyone is curious, this seems to be working for me at the moment in my python lop:
#current node node = hou.pwd() #current stage stage = node.editableStage() #path to source prim source_path = "/Render/Products/Vars/N" #name for target target_name = "copy" #get source prim source=stage.GetPrimAtPath(source_path) #define target path target_path = source_path.rstrip(source_path.split("/")[-1]) #create target prim target = stage.DefinePrim(target_path+target_name, source.GetTypeName()) #get a list of all the properties on the source prim properties=source.GetProperties() #loop through all the source properties for property in properties: #get property name property_name = property.GetName() #get property value property_value = property.Get() #get property type property_type = property.GetTypeName() #if the new render var doesn't have the current property if not target.HasProperty(property_name): #create the property target.CreateAttribute(property_name, property_type) #set the property on the new render var target.GetAttribute(property_name).Set(property_value)

Another approach would be to use DefinePrim to create the new prim, then adding a Reference on the new prim that points to the original. The difference with this approach is that any changes to the original prim will now show up on the new prim too (which may be good or bad depending on your use case).
