Hello -- I recently discovered that it's possible to automate the render or view capability of an object via the Outliner: https://blenderartists.org/forum/showthread.php?237747-How-can-i-hide-object-during-animation
This is a fantastic feature, but I need a way to select multiple objects and automate their render or view capability simultaneously, particularly in a parent/child scenario. For example, let's say I have a parent object with 100 child objects. If I want all of those objects to not be rendered, it's very tedious to right click on the render icon of each of those objects in the Outliner and and choose "Insert Keyframe" from the popup menu. In my custom Blender fork, I've added a right-click menu option for the Outliner called "Insert Recursive Keyframes" and have implemented the following code. Right now, I'm able to set the keyframe for the initial object that I right-clicked on. I can also iterate through all of the other buttons in the outliner and set a keyframe for the same type (i.e. if you right-click on a render icon to set a keyframe, this code will set render icon keyframes for *all* of the objects in the scene). Now for my question. I cannot figure out how to determine what a uiBut object *is* in relation to the actual Blender object in the scene. In other words, I can see all of the properties of the uiBut objects that I'm iterating through...except for the actual Blender object name that is somehow tied to it. Since I can't figure out the Blender object name, I can't determine if the uiBut object that I'm looking at is a child of the uiBut object where I just inserted a keyframe.Or maybe I'm going about this all wrong and there's some other way to determine if one uiBut object is the child of another uiBut object. I've been looking at this for hours and I haven't been able to figure out how to do it. Any help would be greatly appreciated!
