#region Description
// Description by DemonicSandwich from http://remnantmods.com/forums/viewtopic.php?f=13&t=1574 (matches my previous observations)
// Format 6 uses Keyframes the way there are supposed to be used. As KEY frames, with the majority of the frames being Tweens.
//
// This format adds two extra blocks of data to it's structure.
// One block that determines how many Keyframes each Node will have, and an offset to to where it's Markers start from.
//
// Advantages:
// This format requires far fewer Keyframes to make a complex animation.
// You do not need a keyframe for each render frame.
// Disadvantages:
// It's a bit more complex to work with.
// Since it's Keyrame Markers are only 1 byte in size, you're animation cannot be longer than 256 frames, or ~8.5 seconds for non - machine objects. > 12 bits for gen3, max 0xFFF frames
// Machines are still limited to 256 frames but the frames can be stretched out.

// Just a block of flags. Tick a flag and the respective node will be affected by animation.
// The size of this block should always be a multiple of 12. It's size is determined my the meta value Node List Size [byte, offset: 61]
// When set to 12, the list can handle objects with a node count up to 32 (0-31).
// When set to 24, the object can have 64 nodes and so on.
// The block is split into 3 groups of flags.
// The first group determines what nodes are affected by rotation, the second group for position, and the third group for scale.
//
// If looking at it in hex, the Node ticks for each group will be in order as follows:
// [7][6][5][4][3][2][1][0] - [15][14][13][12][11][10][9][8] - etc.
// Each flag corresponding to a Node index.
