TCB Controllers

[bboy-tiger-]

Are those critical for Wc3 animating ?
Why would we need to use those ?
And I'm not sure but I think those controllers cant be modified in tangent editor, or Curve Editor right ?
Can I change Euler controllers into TCB ?

I know they were used in max4 and older -.-'

TCB controllers are just smoothing controllers.

In wc3, there are 2 types of controllers, linear and smooth controllers. Linear controllers do the animation linearly without accelerations desacelerations, speed is always constant between 2 keys. In othe other hand, smooth controllers allow you to control the smoothness of movement.

Of the smooth controllers supported there are 2:

Bezier and TCB:

Bezier is an smooth controller which uses points instead of tangents, it's very editable and easy to use.

TCB:

uses hermite interpolation and therefore uses tangents. TCB can only be modified with 3 values, tension continuity and bias. Tension defines how constrained is the curve, high tension increases the curve's amplitud, low tension reduces it. Continuity defines the smoothness of a curve, 0 continuity means TCB will act like linear controllers. Bias defines how the curve inclines, if it inclines towards left keuy or towards right key.

I suggest you to use TCB only for rotations, since Rotations doesn't really support Bezier. For others use Bezier.

So there is no other way than using TCB for rotation ? I'm not so familiar with TCB, coz it kinda non user friendly with the graph, and I seen you can modify some graph for each key for the TCB controllers and whole sequence of rotation keys.

I'm having problems adapting end keyframe and first keyframe from some "looping" animations like walk to look smooth, there is some poppin. And since I dont know how to use graph for TCB... can you show me a picture here ? I know only this but...

Possible to convert TCB to other controllers and vice versa ?

just set continuity to 0 in start and ending keys of loop animations. It should fix the pumping.

So what if I'm using this for wc3 ? Check the rotate and position controllers. Will this malfunction or can I use this kind of system for wc3 ? Or convert them maybe ?

BTW here is good info if someone doesnt understand TCB.
