VRS v1.0 - UNDERSTANDING SKELETONS
Now, like I've said before, I'm not the smartest when it comes to this stuff. This is my understanding of Skeletal Movement and how it's affected, though, and will serve to teach you something if you know nothing also.
Above all else, you need to remember that no matter what, Skeletal Weights must equal 1.0. You can divide the weight among as many Skeletons as you want as long as the combined Weights are equal to 1.0. That being said, commence to learning because Mr. T still pities da fool.
- Here is a basic setup to help illustrate how Skeletal Weights affect the movement of a Model. I have 2 Skeletal Objects, a Square Model, and the Skeletal Weight Toolbox.

- I have drawn a dotted imaginary Movement line to help illustrate how different Weights can affect the same Model.
- I have numbered the individual Skeletal Objects and Vertices.
- Also, notice that I have numbers above the Skeletal Weight Toolbox. These correspond to the Vertices, so you can see which Vertices are set to which weight.

- This is what I get when all of the Vertices have a weight of 1.0 on Skeleton-2.
- The Motion Files within the game tell Skeleton-2 to move X-amount of Distance. The Vertices will move that same distance as if they were an extension of the Skeleton.
- Skelton-1 doesn’t even affect the Model because it’s not being referenced by Skeletal Weights.

- Now I have set all of the Vertices to a weight of 1.0 on Skelton-1.
- Skeleton-1 has no Motion associated with it. You can see what this does.
- Even though Skeleton-2 is still moving like it’s supposed to, no Vertex has a Weight associated with so it will move nothing.

- Changing it up a bit here. Vertices 3&4 Still have a weight of 1.0 attached to Skeleton-1.
- However, I changed Vertices 1&2 to a Skeletal Weight of 1.0 on Skeleton-2.
- This means when Motion is called into play the Model is being affected by 2 different Weights.
- Because Vertices 1&2 are set only to Skeleton-2, they will move as before, just like they are an extension of that Skeleton.
- Likewise, Vertices 3&4 are attached only to Skeleton-1. They are acting as an extension of Skeleton 1, which has no movement.

- Now, since no one wants their box twisted [editor’s note : Hehe] I want to set a more fluid movement for the Model.
- I have set all of the Vertices to the same Weight, but I have divided the Weight between both Skeletons. This means they will be affected by both Motions from both Skeletons.
- I left a Ghost Image of Skeleton-2 to help show this.
- Because Skeleton-1 has no Motion associated with it but Skeleton-2 does, the Model is being pulled by both Skeletons equally.
- If I had set a higher Weight to Skeleton-2 the Model would have moved with it more, but would still be mildly affected by Skeleton-1.
- In this way I can adjust how fluidly my Model moves.
