Start learning VFX by taking an online FX course from CG Spectrum, a SideFX Certified School. You'll be personally mentored by professional FX artists who have worked on blockbuster films and best-selling games. The full study pathway is 12 months, and you'll be ready to start applying for junior FX jobs upon graduation. You can also try to learn on your own by downloading the software and watching tutorials online. This can be more difficult, as it's hard to find reliable sources of information, and there's no one keeping you accountable or offering expert feedback on your work.
