Hi Vaillancourt,
I can try to answer some of your questions:
> I’m not sure I totally understand what I’m currently doing.
- Sorry, I don't know either
> Now, I’m wondering, if the Value is OFF (and it also appears to be off
when I debug the code), why is the attribute applied anyway?
- That's how this works, the attribute is applied with (boolean) value OFF.
This might be because the default value is ON, or somewhere above your
node in the tree the attribute is set to ON.
> What would I need to do to have the attribute not applied?
Remove it from your osgt file.
Regards, Laurens.
