Explode Modifier

The Explode modifier is used to alter the mesh geometry by moving/rotating its faces in a way that roughly tracks particles emitted by that object, making it look as if the mesh is being exploded (broken apart and pushed outward).

For this modifier to have any visible effect, there needs to be a particle system on its object. That particle system will control how the mesh is exploded.

Both the number of emitted particles and number of faces determine how granular the Explode modifier is. More of each faces and particles will mean more individual pieces.

Here is a demo video showing a cube with a particle system and Explode modifier. (blend-file).


The Explode modifier must come after the Particle System one in the modifier stack, in order for the former to get required data from the later.

Particle UV

If set, the U value of the coordinates in that UV Map will be overwritten with the age of the particle attached to the matching mesh face (in proportion, from 0 for not yet born particles, to 1 for dead ones).

The V value is set to a constant 0.5 value.

You can for example vary the color of a fragment (face) during the explosion phase, by using a texture with a color gradient along its U axis.

Show (Показывать)
До рождения (unborn)

Show faces when their attached particles are unborn.


Show faces when their attached particles are alive.

Мертва (dead)

Show faces when their attached particles are dead.

Cut Edges

Split the mesh in pieces based on location of emitted particles, instead of using existing faces. This will typically results in a splitting that appears more random.

Размер (size)

Scale each face using the size of its attached particle, once that particle is alive.

Группа вершин (vertex group)

Vertices in this group may not be affected by the Explode modifier. Vertices with full weight are not affected at all, while vertices with less weight have a higher chance of being affected.

Vertices with null weight will be treated like those which do not belong to the group at all, and explode normally.

Переставить <->

Инвертирует влияние выбранной группы вершин, что означает, что теперь группа представляет вершины, которые не будут деформированы модификатором.

Эта настройка меняет значения веса группы на противоположные.


Clean vertex group edges. Depending on the weights assigned to that vertex group, either completely protect those faces from being affected by the Explode modifier (which would happen if the faces had a weight value of 1), or completely remove protection from those faces (which would happen if the faces had a weight value of 0).

Dynamic Vertex Weights

This modifier uses the initial vertex weights. Modifiers that dynamically change weights will not influence the explosion as these values are only used once.
