1 (Activate)
Disabling this checkbox, stops all Loony Letters actions. As a matter of fact, it also removes all geometry created by the plugin.
2 (Animate In/Out Tabs)
Enter the values for animating in or out in this tab.
3 (Animate in Parameters)
Start defines at which frame the animation begins, Duration how long the animation will take and Fade-in defines how long the letters will be faded in.
If the checkbox is disabled, the text will fade in as a whole.
4 (Direction and Offset)
This defines, whether the letters will appear from left to right or vice versa. If "none" is selected, the text will appear as a whole. Same applies, if Offset is set to 0. Tthis value sets the timespan between two letters. Values smaller than 1 are also possible, a setting of 0.5 for example, will produce two letters per frame.
5 (Animation and variation values)
With Loony Letters you can transform the 3 standard settings: position, rotation and scale (Note: Scale, not size!!!).
Entering a value in the X,Y,Z (H,P,B respectively) defines the starting position, relative to the end position. Meaning, a position value of X=500 lets the letters appear 500 units to the right of the end position.
Attention: the default value for scale is 1 not 0!
The number field Var creates variations from the value defined above. This is calculted pseudo-randomly. A variation of 50% for a value of 200 will result in numbers between 100 and 300.
6 (Motion spline paths)
Linear movement - the default setting - is boring. With the spline control, you can not only let your letters accelerate or decelerate smoothly, you can also make them swing, jump, whatever you want.
The spline paths work just like C4D's own spline controls.
7 (Knot coordinates, Reset, Copy, Paste)
The X and Y coordinates of the selected knots can be viewed or edited with these numberfields.
Sometimes you get tangled up with the splines and then it is highly annoying to delete every knot individually (dragging it out the grey field). Simply hit the Reset to do this with the click of a button.
On the other hand, it is sometimes very time-consuming to rebuild every sophisticated spline knot by knot. Again Loony Letters offers a one-click solution - simply hit the Copy button and you can paste the spline to every other path control.
8 (Random Seed)
Like mentioned before, variations are calculated randomly - well sort of. Every randomization needs an initiation value. This is the random seed, meaning every identical seed produces identical variations.
9 (Extrude parameters)
Textsplines as such don't have a geometry, that's why extrude nurbs are needed to make them visible. Almost all parameters known from the C4D extrude object can be found here.
Attention: An extrude value of 0 and scaling the Z axis may cause unpredictable results, since 0 times x still remains 0!
10 Preset Load, Save and Quickload buttons
A small but very time-saving goodie are the preset functions. With them you can easily restore to default or save and recall a preset previously created.
And using the quickload buttons lets you store work copies of your settings. Simply hit Set, enter a name and the parameters can be recalled by hitting the Use buttons with just one click.

As stated above, Loony Letters is still in beta stage. It is far more stable and offers much more features than the preceding version 0.9, but unfortunately some things still don't work as expected...

KNOWN ISSUES / BUGS / TO DO

• Loony Letters works with C4d versions higher than 9.1 since it uses COFFEE commands which were added with the latest SDK. There will be no version for R9 or lower.
  
• The recent version of Loony Letters does not support multiline text. Hope to get this fixed soon.
• There are some spelling errors in the user interface, mainly in the Aniamte Out tab, where the checkbox "animate in" and the editfield "fade-in" should of course be "animate out" and "fade out"
• Loony Letters is supposed to be attached to a text spline only, however it is still possible to assign it to any other object. This will only result in error messages. Will be fixed in the next release.
  
• When another object is selected while rendering, it is possible, that the rendering stops or hangs up. Working on it....
  
• When entering an X or Y value of a spline knot, this knot's Y position will jump to the cursor position, when another knot is selected. Don't know, why this is so, but hopefully this issue will be resolved in the next version.
  
• Extrusionparameters are not stored correctly. When using multiple Loony Letters tags, all of them have the same extrusion values.
• Reactivating a Loony Letters tag too quickly one after the other, can result in strange behaviour. This is, because reloading the stored values is interupted and so default or wrong parameters are loaded.
• It can happen that letters are transformed in position, rotation or scale even though no value is entered. I guess this has to do with the variation parameter which is stored in the tags base container. If you stumble over this issue, please let me know what settings you made or how this error can be reproduced. At the moment, I haven't got the slightest clue, how this issue could be resolved
