where do you get the inspiration for cool effects from
u/cantelope

dweets are sometimes harder to be ultra specific with a goal, due to the obvious constraints, but a big piece of my whole graphics repertoire is 3D math, sooo myself? haha not sure
u/tomxor

So true. More often it's just the gradual emergence of "what if"... then after a while it may or may not fit, or by the time you've played with it long enough something else tangentially related emerges. It's all part of the fun.
