Modelled some neurons in C4D, used a simple gradient in the luminance channel to create the action potential. Then threw it into AE for a little extra oopmh. Tried to get the gif as close to a perfect loop as I could.
Trying to keep the ol' Zbrush skills sharp, so I've been working through Pluralsight's Zbrush tutorials. Enter the world's grumpiest alien. Really great tutorials, especially love being able to turn on closed captioning.
