On the Attribute Manager’s Node Properties page, you will find an option called Inputs First. If this option is enabled, nodes that are outside the selected XGroup are evaluated first. This is especially important when the XGroup receives values from the nodes, to ensure that the XGroup receives up-to-date values.
This option allows you to switch the XGroup on (active) or off. The nodes inside the XGroup will only be processed if the XGroup is active. You can also switch the node on by passing a Boolean value of True or the value 1 to its Enable port.
You can password protect XGroups using this button, which will hide the contents of the XGroup until the password is entered.
To protect an XGroup, first choose View / Locked to lock the XGroup’s contents. In the Attribute Manager, click on the Protect button. In the dialog that opens, enter your password for the XGroup. The XGroup will now be password protected.
To unprotect an XGroup, you do almost the same as you did to protect it, except in reverse. First, click on the Unprotect button and enter your password into the dialog that appears. To reveal the contents of the XGroup, disable View / Locked from the context menu and choose the desired display mode from the context menu’s View sub-menu.
