here are two other ways, if you don’t have sketch and toon.
1. Make a quicktime of your Animation in After Effects.
1a. open C4d, make new material, in color on texture, to the right of texture you see the little dots.
1b. click the dots and select your video
1c. make a shape, plane, or whatever, and drop your material on that.
1d. if you want the text only, go back into your material, under alpha, select your quicktime again.
This one is harder, and more time consuming
2. Make a text spline and make a extrude nurb
2a. click c to make it editable
2b. go to object face mode. it’s on the left of you screen the 4 squares with 3 dots on them click it
2c. at the bottom of your screen, right below your timeline there is a grid of 9 dots. click it
2d. now you can key frame the letter building itself.
