A few days ago I was showing a friend some of the animations I’ve made in Blender, and he asked if I could make a short intro for his YouTube videos. What he wants is for some primitive shapes, such as a torus and a sphere, to transform into text. How would I accomplish this, if it is possible in Blender?
Yes it is possible, and by several methods - one is to use Shape Keys - have the “Basis” key with the vertices as the “shape” and a “Key 1” as the same vertices arranges into the letter/text. Its quite a lot of work to do this and without images of what you are proposing it is difficult to answer you properly.
