Destructionx_0_3

Destructionx

this is a digital asset crafted in a simple yet clever way for sidefx Houdini

Destructionx is the simple node to give you a fast and decent destruction effect for any Geometry in Houdini and every software that supports HDA [Houdini Engine] like Epic Unreal Engine or Unity etc.

Feature:

Simple, Flexible, quick setup
Smoke and dust using pyro and vellum solvers
individual outputs for each element
support animated deformed geo as a guide
support velocity for guide geo
Auto-checking for an updated version
Real Impact for a more realistic result
MPM Source as Input
Open setup for modification and customization
Customizable fractured object as input
RBD Simulation as Input
Force as Subnetwork (only RBD Force)
Smart Explosion using Pyro
Visualization for speed workforce

Inputs:

First: it will take Geometry for destruction, edit Fractured Packed RBD object or prebaked RDB Sim and MPM Source (drag distructionX node as containers and add ‘/container_MPM’)as input
Second: it will take guide as geo with “v” for guiding the simulation (it can be animated or deformed) and if you want static object as collision you can create RBD configure node and set the active to 0 (dynamic= active to 1) and use RBD pack and connected

Real Impact:

using chop to miniplate timescale to achieve realistic results

Sleep: will set active (Main Geo) to 0 until the Impact
Frame: which frame will impact happens
Duration: of Time warp Happening (Frame)
Time Warp: How Much speed will apply
Shockwave: Response force for Impact

MPM Solver:

using the latest MPM Solver For combining different elements with the Simulation

Solver Quality: this basically particles separation for MPM Container
Holder: this will use the same MPM Source Object with (Y) Offsets to prevent object from falling
Sticky: amount of sickness its will apply to container and collider
Memory & Rest Sim: it’s apply globally to all solvers

Pieces:

this will add element for falling pieces after RBD Sim

Smoke Amount: how much smoke will emit from flame
Trails: you can select pieces from pieces selection to have smoke ,fire or both
Explosion: can have apply to Real Impact ,pieces or both and you can offset shape and multiply the size
Dust: can apply to pieces ,Explosion or both now
Explosion Amount: how much particle emit when explosion happen

First, pick geo to destruct and then pick geo guide velocity attribute on it to guide the simulation we recommend first working on the destruction look and then adding smoke and dust for Efficiency

if you want to add dust and pyro you can simulate RBD first and go (timeline) to the destructions part and change Visualization mode to Pyro Selection (in case adding pyro) then pick the pieces you want to have smoke with pieces size (base on size) and pieces speed (base on speed) after that set Visualization mode to simulation
