Thanks for your efforts and reply.
At the moment I am most interested in point 3. So the workflow using Body Paint.
But I don’t know what you mean by 4D Paint? I guess it’s about a Kent Barber plugin, but I don’t know where to find it and what it does.
Thanks again for your efforts and help.
PS. In fact, recently the climate has become strange, but I, for example, chose Cinema 4D for my company after a solid economic analysis and the need for tools at our work. And Cineam 4D still turns out to be the best choice!
