Thanks! It's great to get all the good feedback 😁
It is an open source program called Blender, and you can use it for free without any problem. I have made some video tutorials but they are in Spanish, surely you can find many in English 😉

Thank you, I will look for it and maybe I will study how to use it..

You're welcome.
It's great, be careful when you start learning, I slept very little when I was doing it, I didn't stop, don't let the same happen to you 😁
