Verify if a certain parameter/property exists.

Is there a way to verify in ICE if a specific parameter/property exists?
For example, I want to check if a camera has a lens shader (Bokeh_mia) applied to it.
I want to create a boolean value from that and use it as a condition for an IF statement.

I've just started out trying to learn ICe and this might be a basic question but I haven't found the answer online (Maybe I'm just formulating it wrong).

You can use a First valid node to check if a parameter exist or not and return an alternative value.

Hope it will help you 🙂

Just tried it quickly and it seems to be working for what I need. I'll play around with it to see what I can do. Thanks a lot!
