Let me just geek out a little, and say my favorite flipboard in Overwatch is this one.
Love the Pharah rocket impact so much. Its the kind of FX I’m most interested in lately. Its cartoonish, snappy feels anime inspired. This particular flipbook is played back at like 30 or even 24fps, so its ever so studdery just like anime fx animation where they hold frames, and it feels great, while being so counter intuitive.
This kind of FX is also outside my comfort zone as I’m normally a simulation realistic fx guy. But I grow tired of that (whats that Zenyatta FX guy?) I want to get better (as a lot of us here do) at hand drawn fx. I’m sure the person who made this is on this forum. I’d be super interested to hear whatever you’re willing to share on workflows to create a flip book like this.
My guess is.
Draw silhouette shapes in illustrator.
Make b/w gradients from that in photoshop
Color = Lerp between yellow-red based on flipbook in material in engine.
even if thats the way any tips always help. Especially on making gradients on curves.
