Good news is, you can focus on whatever you want. People usually become a master at one skill, be it modeling and do a lot of modeling, or texturing r sculpting or animating, etc. On the other hand, people also become a generalist, they can do a bit of everything or even a lot of everything, but that’s like superhuman level. So there’s no right or wrong answer here, it all depends on what you want to do and focus on. If you ask me, the order goes as follows:
Concept art -> Sculpting -> Modeling -> UV’s -> Texturing/shading -> Lighting -> Composition/layout -> Rendering/Compositing -> Rigging -> Animation -> Tracking -> VFX -> Simulations.
Each stage of the pipeline is a world full of information, each stage is basically a whole career in which you can get lost in and become a master. And if you decide to tackle Modeling, it’ll take a lot of time and practice. Same for any other stage of the pipeline. When I was starting to learn 3D, I spent a couple of months in each stage before moving into the other, until I didn’t feel comfortable in one I didn’t move to the other.
So the question is, where are you in the pipeline? What’s your interest? That way we can link you a couple of courses.
