There are two common, and conflicting “issues” that I see people new to VFX fall into.
The first one being the perception that there is an bottomless pit of knowledge that they need to learn before they can even begin making effects.
The other is they discount a lot of game dev topics they could learn because the topics “aren’t related to VFX”.
These are both fallacies because almost everything you can learn is in some way useful for VFX, and while the pit truly is bottomless, there’s no requirement to learn all of it to start. Also no one knows everything, and there’s no one true way to do something. It’s one of the things I love seeing with the competitions here on the forums. The number of different techniques people use to accomplish the same goal is astounding.
