The 2D tab should be there if you started a new project using the 2D Template. If you didn’t, that’s fine. You’ll just need to add the 2D Packages you’ll want in the Package Manager.
Window → Package Manager
You’ll want 2D Sprite for sure…then maybe 2D Tilemap Editor, 2D SpriteShape, 2D Animation, and 2D PSD Importer depending on what you want to make.
Thank you! I will try this tomorrow to see if the packs were just missing, this was my first project so the 2D packs should have been installed already but I will install them tomorrow.
