Questions tagged [modifiers]

Modifiers are automatic operations that affect an object in a non-destructive way. Use this tag for questions pertaining to modifiers and their usage inside of Blender.

Modifiers are automatic operations that affect an object’s geometry in a non-destructive way. With modifiers, you can perform many effects automatically that would otherwise be too tedious to do manually (such as subdivision surfaces) and without affecting the base geometry of your object.

There are four groups of Modifiers:

  • Modify
    Modifiers in the Modify group act simpler than those in the Deform group without directly affecting the objects shape, rather than affecting some data.

  • Generate
    The Generate group of modifiers directly modifies the shape and/or Topology of an object.

  • Deform
    The modifiers in the Deform group affect only the shape of an object without changing its Topology. These modifiers are often available for types of objects other than Mesh objects such as curves, text objects, and so on.

  • Physics
    Physics modifiers are mainly used (except for the Explode, Ocean, and Particle Instance modifiers) to define where in the Modifier Stack a physics simulation takes place.

Blender's Modifiers are listed in the manual.

  • Modifier Stack
    Blender's modifier system is handled in a "stack" that can be thought of as a sort of assembly line. Each modifier is a process that is fed the outputted object of the modifier above it and in turn modifies and outputs that object to the next modifier in line or, if no more modifiers exist below it, as the final result.

How can I use an array modifier to create individually manipulatable objects?

I often use an array modifier (or two) to quickly create a grid of identical or symmetric objects, which can be really useful when modeling all sorts of man-made objects. Once I've made the grid, though, is there any way for me to make it so that…

Boolean Difference with Offset?

Is it possible to create a Boolean difference with a defined air gap (offset) between object A and object B (see picture below)? This is particularly interesting for 3D printing operations, where one physical object needs to be set into another. So…

Smooth displaced mesh

Whenever I use a Displace Modifier, it looks like it does no interpolation of my height map. Green is how it should be, Red how it is. Notice how the mesh is dense. The texture I use as height-map is extremely smooth, it should produce a really…
