Hello ive just recently got into unity 3d and im enjoying it alot. Im very much looking foward to making my own game and im wondering what programs can i use to make my own assets to put into my game. I have a low budjet if this helps.

Also how do you import the tutorial assets from the unity projects what are on the unity 3d website?

Thank you in advance.
