From 2D to 3D

Hi, i have experience with 2D programming and designing.
I want to start using Unity for 3D mobile games as well.
It’s kinda weird that i don’t know where to start because i am using Unity for approximately 2 years.
Any good Tutorials on Udemy/Youtube that you suggest?
Thanks

Start from the beginning.
Learn how to move and rotate cube. How to roll a ball etc.
These are also keywords to search for.

Btw, is no point using paid Udemy. All is there on the web.

Unity provides lots of free tutorials here:

Most are for 3D.

Ben Tristem has an older tutorial series on Udemy that covers 3D.

Aside from that I recommend just going through the project tutorial series provided by Unity.
