Another shader based on Alien, this one was an exercise in modelling and animation.
I started off with the dome of the head and the texture on it. It’s actually a simple gyroid pattern with a few colors mixed into it, but quite effective!
My awesome cousin (Check out his art here) gave me some tips for the animation – I added some ‘anticipation’ before the alien strikes. This means the head pulls back before striking forward, showing a build up of ‘energy’ and really improving the effect.
