Hey @Ubi_Bubi1!
Which do you mean by βItβs the effect I want to achieve?β Iβm assuming you mean chaos destruction. In these examples the closest thing would be the Spyro example. The Zelda one is pure visual effects, and the GoW one is about halfway between.
I found that this was a good introduction to the Chaos destructible mesh system- you can get something pretty achievable with your own meshes with very few changes!
