There’s this Udemy course by this dude Ben Tristan had unity courses on Udemy for like 20$. Start with 2d then do 3D modeling or the 3D course. I started getting migraines and thought I had a brain tumor or something crazy and got these courses and then really close to finishing a solid alpha in about 4 months. I finished each course in about a month and was always taking what I learned and applying it to a few experimental projects. I’m fine now but that’s what I was doing when I thought my days were matched.
Here’s his 2d, you can skip it but there’s cool tricks you don’t learn in the 3D and it makes the 3D a lot easier:

Ben and all the instructors are insanely knowledgeable and there’s a lot of help in the forums on it. I’m still active on them sometimes.
