I've been learning Houdini lately, mostly the off-road tools for work. Of course I also want to integrate it into my VFX trip, so I came up with an HDA to tear my assets apart and prepare them with the data to be animated.
I thought it would make sense to grumble the stuff from the outside in, so I put the information on how far the parts are from the center into the red channel.
It doesn't look right in the animation you see. So next time I prefer to start from the center / bottom point.
The rest of the effect is a vertex animation in the shader. The tremor before the crumble should arouse some anticipation as long as you hold down the teleport button. After releasing, the crumbling begins. I have to do a lot more to sell it
