Step 1

Aim at the surface

Shift + right-click where the hit should land. The 3D cursor is the impact point: a top face blows pieces up, a side face punches through.

Step 2

Pick a preset, press Destroy

The preset menu holds the eight starting points. Destroy breaks the object batch by batch and glues the pieces, so it holds until the impact frame. Esc cancels and leaves it untouched.

Step 3

Bake and play

Bake Simulation stores the physics, the debris and when each piece breaks. Press play and it runs in the viewport.

Step 4

Change anything, see it again

Speed, radius, pieces, glue, edges: change a value, re-bake, play. No rebuild, and the original object stays in the file.

Rocket Strike

An object blown apart from the point of impact.

Meteor

A hit from above: a crater, debris thrown up and out.

Wall Breach

A side impact that punches through a wall.

Shockwave

A ring wave rolls outward through the surface.

Slice

A clean cut: shards along it, the halves pushed apart.

Cannonball

A physical ball flies in and smashes through.

Demolition Path

Charges go off one after another along a curve.

Crumble

No blast: the glue lets go and it falls under its own weight.

Draw the blast path

Demolition Path follows any curve. Pick your own Bezier curve, or press the pencil and draw the path straight onto the surface. The first point fires first.

• Charges: how many go off
• Detonation Speed: how fast they run
• Damage Radius: how much breaks around the path

Rebar that bends and snaps

Tick Rebar and steel bars run inside the concrete.

• Stick Out: bars poke from the cracks
• Bend & Snap: bars bend with the chunks, then break

Rubble, dust and slow motion

Rubble in the object's own material, dust that needs no bake, puffs where pieces land, and a speed curve that slows the hit and everything with it.

• Debris amount and size
• Ground-hit dust
• Slow Motion: Slowest From, Speed, Hold, Ease

Fresh faces that match

The inside of every break gets its own material that matches the outside: concrete, asphalt, dirt, brick, stone, wood, glass, metal or plaster.

• Edges: Clean, Jagged or Chunky
• Bevel Edges for softer chunks

One destruction, a whole row

Bake to Keyframes, then Make Tiles: copies of the destruction down a row, each going off a little later and turned at random, with their own pieces and dust.

• Copies, Offset, Delay
• Random Turn and Tile Seed

Rubble that lands on your scene

Add Colliders to steps, floors or vehicles and the pieces bounce off them. A destruction on a moving object rides along until the hit, and Mantaflow smoke is one checkbox.

• Add Colliders / Remove Colliders
• Smoke Simulation, then Bake Smoke

Bake to Keyframes

Turns the simulation into plain keys. Back to Simulation brings the physics back.

Render Farm Copy

Writes a file that renders on machines without Krater installed.

EEVEE and Cycles

Renders in both engines, on Windows, macOS and Linux.
