This is a great question!
I feel like as someone who is more technically inclined, I don’t have much grasps of the fundamentals of art. I was thinking if I went back and started to get the basics down – such as perspective, color theory, composition, light, etc. then I would have a much better chance at understanding art in the 3D world.
Short answer – yes it would! That said, you don’t have to completely drop 3D for a while, unless you feel like you want to. You can still focus 80% on 3D and 20% on sketching or something. At the very least, watch through the CTRL Paint composition basics videos.
I totally know what you mean! I’m certainly not great at 2D art, but I do see how practicing it improves my 3d work. Try sculpting for a while. It’s kind of like the 3d equivalent of sketching, and will help you improve your observation / shape creation skills. Or, if you really aren’t feeling it, dive into Rigging or Python and max out on the technical side.
Which 3d courses have you gone through on this site? As much as it may be frustrating not to make ‘your own’ work at first, following a tutorial can give you enough direction with which you can then expand on with your own ideas.
Best of luck and don’t give up! We’ve all been there.
