Hi,
to break all letters from a text you must set the SEPARATE LETTERS on text then MAKE EDITABLE.
No you must have a null with all letters like curve inside.
Add extrude nurbs and drag the Null inside then enable Hierarchical in extrude then MAKE EDITABLE.
You must have a NULLA named EXTRUDE NURBS, Null Called TEXT and at last, a NULL Callet TEXT with all EXTRUDE CURVE INSIDE.
DRAG OUT the NULL Called TEXT with all extruded inside out and make keyframe for all EXTRUDED BLOCK.
now you can add nota tag to this NULL.
You must learn how is working Separate Letters and Hierarchical on extrude and is not NOTA job but Cinema 4D job.
Now i’m busy but in few hours i’ll make for you a quicktime with all steps.. maybe that i’ll use audio 🙂
I hope this help
