Text editing in Model Editor question.

[Spacebuns]

In the Node Manager, bones' movement can be modified by editing the parameters in 3 windows: Translation, Rotation, Scaling. While Translation and Scaling have 3 sub-parameters representing {X, Y, Z} axis, Rotation has 4. The first 3 are XYZ but what does the 4th one represent?

That's a rotation as described by quaternions (hypercomplex numbers). It's kind of tricky.

You can use this calculator. Enter the XYZ values you want as rotations in degrees (I think XYZ in this calculator is the same as XYZ in Magos - X for back to front axis, Y for left to right and Z for down to up, but I'm not sure) and it will convert it to the four quaternion values.

So the four values in the Rotation fields are four quaternion values, I get it. But in the text editor, which values correspond to q1,q2,q3,q4 in the quaternion calculator respectively?

Probably (q2, q3, q4, q1) aka (x, y, z, w), but you can just try and see.
