Amazing, that's it. Thanks a lot once again.

Interesting. I'm trying to recreate it but it's not working for me: I connect P to null_1, then that to null_2, then make a subnet out of null_1, inside there is the Subnet Inputs node, then build the logic there. When done, if I disconnect P outside I get an error, so I guess it only works with hda's. So I create an hda, then test again, but when I disconnect P I get black as output again. What did I do differently?

Thank you, the problem is that my actual need is to use "Position" instead of color, that was just the simplest scene possible, I guess it was too simple then.

So, what I really need is to output the connected position ( when it is connected ), otherwise output uvs ( from UV Position node )
