This project is a test of a sand castle destruction with molecular particles.
As a result, I used a blender addon which permit self collision and linking particles. This addon seems to simulate sphere for each particule, and have a parameter to spawn a link between all. So, it permits to break this link if the force is high enough.
With this premise, I had the idea to modelling a castle in sand and try to smash it, realisticly, with a beach ball.
Finally the entire project was made in blender, because this (super) software permit to assure all pipeline phases with high quality results (too bad it’s not really use in AAA studios).
