Hello,  
I need to create a custom node that one of its inputs is an intance object that has been created by a class in a python script. Does anyone know what should I write on the input node for it to work?

Thank you!

I’ve tried it but did not work… I tried also using var[], because my input needs to be a list, but still not working…  
Thank you!
