Build an ordered 3D modifier stack

Add, reorder, expose, and animate generate, deform, and constrain modifiers while keeping the original 3D object editable.

Where: 3D editor → select an object → Modifiers

Key ideas

Ordered evaluation: The stack runs in order: generators establish or duplicate geometry, deformers reshape it, and constraints place/orient it relative to other scene data.
Non-destructive parameters: Each modifier retains editable parameters and can be enabled, reordered, or removed without baking the original mesh.
Animation exposure: Supported numeric parameters can be exposed to the timeline and keyframed; path-related deformation/follow controls can drive travel or bending.

Select a compatible 3D object and open Modifiers.
Add the generator/deformer/constraint you need and set a visible test value.
Reorder modifiers while watching how upstream output changes downstream stages.
Expose the numeric parameters that need animation and keyframe them on the timeline.

Build from broad geometry changes to fine deformation/constraints.
Disable a stage temporarily to diagnose which modifier causes an unexpected result.

Check object compatibility, value range, stack order, and whether an earlier stage produces geometry the modifier can affect.
