Adding animation nodes to keyframes

[Failed_Hero]

As many of of have seen with my previews, I have worked my behind off to learn how to scale keyframe nodes to make weapons and other objects appear and disappear convincingly.  I had some help from both beyonder and white_knight in learn to scale.  But there is one thing that has alluded both myself and few other skopers and hexxers, adding nodes NiNodes from one keyframe set to another. This elusive prize would allow for so much great work to be done.  I have only a limited knowledge of Nifskope and blender, this is a request, a plea really to help advance some projects for not only myself but several skoper's and hexxers.

Here is what I know from looking at a keyframe set.

1. The animation is bundled in the NiSequenceStreamHelper
2. When working with unconverted keyframes the NiSequenceStreamHelper opens to NiTextKeyExtraData (which contains the skeleton list that corresponds to the NiKeyframeController) and the NiKeyframeController (is the directions for the skeleton and objects)

I know that you cannot simply copy branch and paste branch as when I have attempted this it does not fall in the NiSequenceStreamHelper and is added to the list of keyframes.

This is what I know. I wish I knew more, and that is why i posting this topic.  I believe that as a community we all of our shared experience we can figure out this issue that will lead to great advances in skoping.

Sorry to bring this to life again, but has anyone solved this problem???

For appearing and disappearing I normally look at what I need and then just pick a set of existing key frames that match as close as possible.

I do know how to replace one item with an another in Blender, like with Popeye where he pulls a can of spinach out for a special action

For making new keyframes, I think that SA would be the one to talk to. He's done some amazing things with kfs. Maybe dm as well

Failed_Hero,  I think the issue you are having here is due to using unconverted keyframes.  The  keyframes do have a strict hierarchy, and I was never able to insert keyframes properly into that hierarchy.  If you use converted or    keyframes, everything is kind of even or balanced out.  then there is no issue in adding NiNodes to existing keyframes.  One thing to keep in mind though, if you scale up or down something like a weapon or set of wings or whatever that you added to the keyframes, you'll have to add in instructions for that node in other keyframes as well.
For example, maybe a character has a knife for one melee animation.  During that animation the knife will scale up for the attack, and then by the end of the animation it scales down to nothing. You'll want to add to the melee_idle, idle, run and other keyframes info to keep that NiNode scaled down.  Ideally, you would put that in every animation in the keyframe set.  I'm lazy, so I used to just put that into certain keyframes like Melee_idle, idle, and run,  as those animations kind of 'reset' the character. I'm sure you are aware of this already, and it's pretty easy to do with converted keys.
I was never able to get it to work with unconverted keyframes though, that hierarchy thing was too weird.

Would it be possible to change the total number of controlled blocks (num controlled blocks), for example, by adding one or more controlled blocks, then pressing the update button (green button), which would then update the list of controlled blocks to a higher number? The new controlled blocks would not have any information, so it would be necessary to enter the name of the node that is to be animated. Then probably i would need to insert the coordenades for the animation using Sick Alice's animation trick.
