Le modificateur Surface Deform

The Surface Deform modifier allows an arbitrary mesh surface to control the deformation of another, essentially transferring its motion/deformation. One great use for this is to have a proxy mesh for cloth simulation, which will in turn drive the motion of your final and more detailed mesh, which would otherwise not be suitable for simulation.



The Surface Deform modifier.

The object to which to bind (this setting is unavailable after binding).
Interpolation falloff

How much a vertex bound to one face of the target will be affected by the surrounding faces (this setting is unavailable after binding). This essentially controls how smooth the deformations are.


While lower values result in smoother deformations, they may also introduce slight artifacts.

Bind the current state of the modified mesh to the current state of the target mesh, such that any later change in the target mesh will deform the modified mesh as well. Note that until the bind has been executed, this modifier will have no effect at all.
Once the mesh is bound, the Bind button changes to Unbind. Executing this frees the modified mesh from the target, and resets it to its original shape.


Les maillages sont liés au niveau des coordonnées globales, mais des transformations ultérieures sur les objets seront ignorées. Ce qui signifie qu’on peut librement transformer la cible ou l’objet modifié après la liaison, sans affecter l’objet modifié. Le maillage modifié va seulement reprendre les changements au maillage de l’objet cible lui-même.


Plus un maillage se différencie de la surface de maillage cible, plus il est probable d’avoir des artefacts indésirables. C’est une caractéristique inhérente de la liaison de surface en général, ainsi il est recommandé d’avoir des maillages convenablement équivalents, pour obtenir une bonne liaison.


Target Mesh Validity

While there are no restrictions with regard to the modified mesh, the target object’s mesh has a few constraints, which if not followed, will prevent a successful binding:

  • It must not contain edges with more than two faces.
  • It must not contain concave faces.
  • It must not contain overlapping vertices (doubles).
  • It must not contain faces with collinear edges.
