Hello @Dunhou,

Thank you for reaching out to us. In C++, you would retrieve the attribute maxon::nodes::PortType (id: "type") on the node. There are also some attributes of similar purpose which return a maxon::DataType for a GraphNode.

However, none of these work, because there is a bug in maxon.DataType (i.e., the Python API reflection of maxon::DataType). Currently there is nothing you can do from the Python side of things to fix this. I have filed a bug report and flagged this thread as to_fix.

Cheers,
Ferdinand

Result:

GetName(port) = 'standardmaterial@Hg9$KeW8OFNmebDk8jn99C<com.redshift3d.redshift4c4d.nodes.core.standardmaterial.bump_input' port.GetId() = maxon.InternedId('com.redshift3d.redshift4c4d.nodes.core.standardmaterial.bump_input') <class 'maxon.datatype.DataType'> <NativePyData (net.maxon.datatype.datatype) [dt=0x00007FF7EC8692C0,data=0x000001A756F0A370,owner=false] object at 0x000001A756F0A340> <class 'maxon.datatype.DataType'> <NativePyData (net.maxon.datatype.datatype) [dt=0x00007FF7EC8692C0,data=0x000001A756F02770,owner=false] object at 0x000001A756F02740> <class 'maxon.datatype.DataType'> <NativePyData (net.maxon.datatype.datatype) [dt=0x00007FF7EC8692C0,data=0x000001A756F16670,owner=false] object at 0x000001A756F16640>

Code:

def RetrieveInformationOfPort(port: maxon.GraphNode) -> bool: """ """ if not isinstance(port, maxon.GraphNode): return False print (f"\n{'-' * 100}") print(f"{GetName(port) = }") print(f"{port.GetId() = }") # Try out various node attributes that express a type. for aid in ("type", "fixedtype", "synthesizedtype", "net.maxon.node.deducedtype"): # We can get these attributes, but they all return malformed data. There is a # bug in maxon.DataType itself (the type of all of these attributes). attribute: maxon.Data = port.GetValue(maxon.InternedId(aid)) if attribute is None: continue print (type(attribute), attribute._data) # All these lines will fail, because #attribute is malformed in the Python API, # its field DataType._data is not what it should be. # print(attribute) # print(attribute.GetId()) # This would be data type of the port.

How about updating ResEdit..?
