Stefan Kleindienst (Unexpected) thinkingParticles demolition of skyscraper!

"Want to share some recent RnD with you.
The goal was to create a Thinking Particles Tool, which is fully procedural, fast and flexible for a variety of destruction cases.
I mostly used distance- and velocity thresholds for the activation.

There are three levels of procedural volumebreaking (prefracturing, secondary fracturing on activation and finally on floor contact).
Same for the joints. Based on the distance radius, i implemented glue-rules between different combinations and levels of fractured pieces, which break on velocity changes.

On top of the SC-cache, non-physics-debris pieces and volumebreaker noise (many thanks to Martin Kossmann, who has shared the "roughness-technique" in the cebas-facebook-group!) are generated.
I also emit and lock some broken metal-bars to the inside faces of the chunks, but it's hardly visible.
I
've to tweak the debris emission for the actual shots but i think the system, in general, fits our needs.

Critics & Comments are very welcome :)
