Auto-execution Cycles Node Trees I have noticed that Blender doesn't redraw changes in Cycles Node tree when they made with Custom Property via scripted Drivers. I need run animation to see changes in real-time, but it isn't handy always.

For example, Animation Nodes have such feature:



And it is very helpful.

I want to know is it possible to get something similar for Cycles Node Tree natively or with some addons/scripts?

Thank you for any tips and answers.
After all I didn't find solution for Cycles Nodetree. I'm sure that such behavior is due NodeGroup and can't work in different way at the moment.

Like Omar Ahmad has advised before, I had rewrite some code and create new Subprogram inside Animation Node tree. When Auto Execution is enabled it allows to see all changes in viewport without active animation, in real-time, even those that are inside NodeGroups.

Be careful if your nodetree has a lot calculations this action can reduce your performance. Use another AN NodeTree for such things. I have attached example below:
