    nice demolition - memory?

      Thanks! I really don't remember, but it was simulated on 64GB machine and I believe there was some space reserve left.

    Looks amazing! Also, curious what the hard drive space requirement was for these sims. The volumes look awesome!!
    One critique from an art direction stand point, the cause of the explosion might not believably precipitate the most upward pieces of the building to fall so soon -some other elements also seem to break apart early instead of stay together with the larger structures. Nice work/render regardless!

      Thanks! There's a weak constraints here, but I left this iteration, because it behaved most interesting for me :)
      All caches have 200GB, that includes all steps like smoke source particles (14GB) for example. Bullet was made with RBDpackedObject, I've saved fractured geometry to file, simulation to points and then used TransformPieces, it helped mi save disk space, upresing with interior detail and work with sim after simulation.
      Here is main simulations details:
      SmokeSim (density only) - 107GB
      SmokeVel (with lower division size) - 28GB
      Explosions - 15GB
      Bullet simulation (points) - 2GB
