The first part of Freya Holmer's three-part, nearly four-hour lecture on shader coding for game devs in Unity. It covers what shaders are, vertex and fragment shaders, interpolators, data types, blending and textures.

Recommended as a good first-steps shader tutorial that also teaches broad graphics knowledge.

[LINK] and a good sandbox is [LINK] and you should consider unity too, this is a good tutorial but also lots of good info about graphics in general: [VIDEO]

For procedural animation: I have yet to find the path to learning this skill. It is very opaque, and I think you just need to attack it with your brain and learn it. For shader and graphics programming: I liked this tutorial series as a "first steps" by Freya Holmér: [VIDEO] Here is another list: [LINK] The Book of Shaders is a popular suggestion, but it appears to be abandoned: [LINK] For general Unreal? Tom Looman's $300 Unreal C++ class, available on his website. It is pricey but really excellent. I also discovered this AWESOME list of learning paths for all gamedev concepts: [LINK]

I've always enjoyed watching The Art of Code[1], Freya[2] also has a good number of videos on it. But that is just vertex shaders for things like Shadertoys. There is much more to computer graphics or GPGPU than this though, Im still learning about that myself X). [1] [LINK] [2] [VIDEO]
