Modifiers

Mode: Any mode

Panel: Modifiers

Modifiers are automatic operations that affect an object in a non-destructive way. With modifiers, you can perform many effects automatically that would otherwise be tedious to do manually (such as subdivision surfaces) and without affecting the base topology of your object. Modifiers work by changing how an object is displayed and rendered, but not the actual object geometry. You can add several modifiers to a single object to form a Modifier Stack and you can Apply a modifier if you wish to make its changes permanent.

There are four types of modifiers:

Modify

The Modify group of modifiers are tools a bit similar to the Deform Modifiers (see below), but which do not directly affect the shape of the object; rather they affect some other data, like vertex groups…

Mesh Cache

Apply animated mesh data (from external file) to a mesh.

UV Project

Project UV coordinates on your mesh.

UV Warp

Dynamically edit the UV coordinates on your mesh.

Vertex Weight

Edit a vertex group of your mesh, in various ways.

Generate

The Generate group of modifiers are constructive tools that either change the general appearance of or automatically add new geometry to an object.

Array

Create an array out of your basic mesh and similar (repeating) shapes.

Bevel

Create a bevel on a selected mesh object.

Boolean

Combine/subtract/intersect your mesh with another one.

Build

Assemble your mesh step by step when animating.

Decimate

Reduce the polygon count of your mesh.

Edge Split

Add sharp edges to your mesh.

Mask

Allows you to hide some parts of your mesh.

Mirror

Mirror an object about one of its own axes, so that the resultant mesh is symmetrical.

Multiresolution

Sculpt your mesh at several levels of resolution.

Remesh

Can fix heavily triangulated meshes, and other issues, with careful Threshold adjustments.

Screw

Generate geometry in a helix-pattern from a simple profile. Similar to the Screw tool in the mesh editing context.

Skin

Automatically generate topology.

Solidify

Give depth to mesh faces.

Subdivision Surface

Subdivides your mesh using Catmull-Clark or Simple algorithms.

Triangulate

Converts all faces to Triangles.

Wireframe

Converts all faces into a wireframe (included in trunk atm).

Deform

The Deform group of modifiers only change the shape of an object, and are available for meshes, and often texts, curves, surfaces and/or lattices.

Armature

Use bones to deform and animate your object.

Cast

Shift the shape of a mesh, surface or lattice to a sphere, cylinder or cuboid.

Curve

Bend your object using a curve as guide.

Displace

Deform your object using a texture.

Hook

Add a hook to your vertice(s) (or control point(s)) to manipulate them from the outside.

Laplacian Smooth

Allows you to reduce noise on a mesh's surface with minimal changes to its shape.

Laplacian Deform

allows you to pose a mesh while preserving geometric details of the surface.

Lattice

Use a Lattice object to deform your object.

Mesh Deform

Allows you to deform your object by modifying the shape of another mesh, used as a “Mesh Deform Cage” (like when using a lattice).

Shrinkwrap

Allows you to shrink/wrap your object to/around the surface of a target mesh object.

Simple Deform

Applies some advanced deformations to your object.

Smooth

Smooth the geometry of a mesh. Similar to the Smooth tool in the mesh editing context.

Warp

Warp a mesh by specifying two points the mesh stretches between.

Wave

Deform your object to form (animated) waves.

Simulate

The Simulate group of modifiers activate simulations. In most cases, these modifiers are automatically added to the modifiers stack whenever a Particle System or Physics simulation is enabled, and their only role is to define the place in the modifiers stack used as base data by the tool they represent. Generally, the attributes of these modifiers are accessible in separate panels.

Cloth

Simulates the properties of a piece of cloth. It is inserted in the modifier stack when you designate a mesh as Cloth.

Collision

Simulates a collision between objects.

Dynamic Paint

Makes an object or a particle system paint a material onto another object.

Explode

Blows up your mesh using a particle system.

Fluid

The object is part of a fluid simulation… The modifier added when you designate a mesh as Fluid.

Particle Instance

Makes an object act similar to a particle but using the mesh shape instead.

Particle System

Represents a particle system in the stack, so it is inserted when you add a particle system to the object.

Smoke

Simulates realistic smoke.

Soft Body

The object is soft, elastic… Modifier added when you designate a mesh as Softbody.

Ocean

Quickly creates a realistic, animated ocean.
