How Cloth NeXt treats this object in a simulation

Practical: Pick the physical role that matches the object. Changing roles changes which panels are relevant; it does not duplicate the object.

Choose a fabric starting point. Editing a material value switches to Custom without resetting your settings

Choose how the surface behaves. Fabric (Baraff-Witkin) is recommended for cloth; Shape Preserving (ARAP) retains the original form more strongly. Solver parameter: model

Mass of the fabric per square meter. Higher values give the cloth more inertia and make it react more heavily, but do not directly make it stiffer. Unit: kg/m². Solver parameter: density

Practical: Use this for mass, not stiffness. Heavier cloth carries more momentum and can need stronger collision and damping settings.

Controls how strongly the fabric resists being pulled longer. Lower values create softer, more stretchable cloth. Higher values preserve its original size more strongly. Solver parameter: density-normalized young-mod

Practical: Raise it when the cloth visibly elongates too much. Lower it for elastic or loose materials. Very high values can make difficult scenes more expensive to converge.

Controls how strongly stretching in one direction affects the fabric sideways. Lower values allow the directions to stretch more independently. Higher values make the fabric contract sideways more strongly. Solver parameter: poiss-rat

Practical: This controls lateral coupling during stretch. Keep it below 0.5; values closer to the upper limit behave more incompressibly in-plane.

Controls how easily the fabric bends and forms folds. Lower values create soft, flowing folds. Higher values create broader, stiffer folds and stronger shape retention. Solver parameter: bend

Practical: One of the main silhouette controls. Low values create small, soft folds; higher values create broader, more structured folds.

Prevents the fabric from stretching beyond the specified percentage. Disable it for unrestricted stretch. Solver parameter: strain-limit

Maximum permitted extension beyond the original size. A value of 5% allows approximately five percent stretch. Solver parameter: strain-limit

Allow sustained stretching or compression to permanently change the Cloth rest shape

Speed per second at which overstretched Cloth adopts its current shape. Solver parameter: plasticity

Stretch or compression required before permanent deformation begins. Solver parameter: plasticity-threshold

Allow folds held under load to become part of the Cloth rest shape

Speed per second at which folds become permanent. Solver parameter: bend-plasticity

Angular deviation required before a fold becomes permanent. Solver parameter: bend-plasticity-threshold

Use the mesh's starting folds as its bend rest shape. Disable for an initially flat rest shape

Reduces oscillation caused by stretching and in-plane deformation. Small values can calm jitter without making the fabric visibly sluggish. Unit: seconds. Solver parameter: deformation-damping

Practical: Use small values to calm in-plane vibration after motion or contact without changing the material stiffness itself.

Reduces oscillation and flutter in folds and bending motion. Small values can calm unstable folds. Unit: seconds. Solver parameter: bending-damping

Practical: Useful for fluttering hems and unstable folds. Increase gradually; too much damping can make motion feel heavy.

Positive values contract the Cloth rest shape; negative values expand/pre-stretch it. +10% gives 90% rest size; -10% gives 110% rest size. Cannot be combined with an enabled non-zero Stretch Limit

Practical: Positive values shrink the rest shape; negative values expand it. Use it for fitted garments, tensioning and pre-stretch.

Apply uniform pressure along the Cloth mesh surface normals. Consistent normals and a closed mesh are recommended for balloon-like results

Uniform outward pressure along the Cloth surface normals

Practical: Requires suitable normals and works best on closed cloth volumes. Increase gradually while watching contact stability.

Treat edges that are not used by any face as Sewing springs and pull their endpoints together

Sewing stiffness for Sewing edges. Higher values close seams more strongly against gravity and collisions

Practical: Controls how aggressively loose sewing edges are pulled together. Start low enough that the seam can close without explosive motion.

Hold vertices in the selected Blender vertex group at their evaluated Bake Start positions

Practical: Pins constrain selected vertices while the rest of the deformable remains simulated.

Practical: Only the selected vertex group participates in pinning. Keep the group intentional and verify weights before a long Bake.

This setting is exposed by Cloth NeXt and is consumed by the current workflow.

Practical: Static pins stay at their Bake Start positions. Follow Animation pins use the evaluated Blender motion of the target.

Animated Empty or object whose transform drives the Pin group

How strongly this constraint pulls toward its Target

Enable collisions for the simulation. When disabled, deformable objects can pass through colliders

Controls how easily touching surfaces slide. Lower values are slippery; higher values resist sliding. Minimum mode uses the lower Friction value of the two touching objects. Solver parameter: friction

Practical: Controls tangential sliding between surfaces. Increase for grippier contact; reduce when garments should slide freely over each other.

Adds a collision skin around the surface. Use small values to represent surface thickness without changing the simulated mesh. Excessive values create visible separation. Unit: Blender world units. Solver parameter: contact-offset

Practical: Treat this as simulated surface thickness / collision radius. On cables it is the main way to represent a physical radius around the centerline.

Distance at which collision response begins. Larger values keep surfaces farther apart. Excessive values can make the cloth appear to float. Unit: Blender world units. Solver parameter: contact-gap

Practical: The contact barrier distance. It is not the same thing as physical thickness or cable radius.

Vertices whose weights blend from the general Friction value to this region's Friction

Target friction at full weight in this Vertex Group

Mass per unit length. Higher values make the cable feel heavier

Practical: Mass per unit length for Cable / Rope. Increase it for heavier cables without changing their stretch or bend response.

Resistance to lengthwise stretching. Higher values preserve length

Practical: Raise it when the cloth visibly elongates too much. Lower it for elastic or loose materials. Very high values can make difficult scenes more expensive to converge.

Resistance to bending. Lower values create flexible cables

Practical: One of the main silhouette controls. Low values create small, soft folds; higher values create broader, more structured folds.

Scale the cable's resting length. Values below 1 contract it; values above 1 make it longer

Practical: Changes the cable rest length. Values below 1 shorten and tension the cable; values above 1 introduce slack.

Maximum lengthwise stretch. Set to 0% to disable the limit

Practical: Caps cable stretch relative to rest length. Lower values hold length more strictly.

Allow bends held under load to become the cable's rest shape

Speed per second at which cable bends become permanent

Angular deviation required before a bend becomes permanent

Use the cable's starting bends as its rest shape. Disable for an initially straight rest shape

Mass per unit volume. Higher values make the object feel heavier

Practical: Mass per unit volume. Change this when a solid should carry more or less inertia; it does not directly replace stiffness.

Overall resistance to deformation. Higher values retain the original shape more strongly

Practical: Raise it when the cloth visibly elongates too much. Lower it for elastic or loose materials. Very high values can make difficult scenes more expensive to converge.

Controls how much the object expands sideways when compressed. Values near 0.5 preserve volume more strongly

Scale the resting volume. Values below 1 shrink the object; values above 1 expand it

This setting is exposed by Cloth NeXt and is consumed by the current workflow.

Practical: Chooses the internal tetrahedralization path used to turn the closed surface into a volumetric simulation mesh.

Allow sustained deformation to change the solid rest shape

Speed per second at which the solid adopts its deformed shape

Deformation required before the rest shape starts changing

Weight per unit volume. Higher values give the object more mass and make impacts feel heavier

Practical: Mass per unit volume. Change this when a solid should carry more or less inertia; it does not directly replace stiffness.

Choose whether this Collider stays fixed or follows its evaluated Blender animation during the bake

How animated Collider geometry is captured

Animated Collider samples per Blender frame. Increase this for fast or strongly curved motion to prevent the interpolated Collider from crossing the cloth

Practical: Higher sampling can better capture fast or strongly deforming animated colliders, at the cost of preparation time and memory.

Choose the generated Collider proxy strategy

Outward safety margin added to every bone hull in world units

Practical: Expands the generated character cage. Increase it when animation pushes outside the proxy; excessive margin reduces collision precision.

Extend bone hulls along the bone axis so joints overlap

Frames between one-time Character evaluations while fitting the cage

Minimum skin weight for a Character vertex to contribute to a bone hull

Ignore deform bones with fewer weighted Character vertices

Approximate vertex target for the generated experimental Collider Proxy

Practical: Lower targets are faster but less faithful. Keep enough geometry around silhouettes and contact-critical areas.

Replace this logical Collider with its generated simulation Proxy during Bake

Gravity acceleration along the independently selected world axis

Practical: Scene gravity magnitude for Cloth NeXt force evaluation.

Wind speed along the Empty's local +Z axis; aerodynamic force also depends on Air Density

Practical: Base wind magnitude. Rotate or configure the Force object as documented by the UI to control direction.

Maximum additional Wind strength during intermittent gusts; zero disables gusts

Practical: Adds variation to wind so motion is less uniform.

Time scale of Wind Variation in seconds; higher values create slower, broader gusts, while lower values create faster changes

Show the four numeric solver quality controls

Simulation step size in seconds. Smaller values can improve stability but take longer to calculate

Practical: Smaller time steps are generally more conservative and more expensive. Change this only after simpler material/contact fixes are exhausted.

Keep verified solver checkpoints so an interrupted Bake can continue after restarting Blender

Ask the solver to save resumable states periodically

Number of solver frames between automatic checkpoints

Practical: Smaller intervals preserve progress more often but create more checkpoint I/O.

Maximum number of verified checkpoints retained

Practical: Keep enough states to recover from a bad latest checkpoint without retaining an excessive number of old snapshots.

Extra space kept around the simulated objects

Practical: Controls how much empty viewport space is kept around live simulation.

Cancel an active Bake after RAM stays above the safety threshold for two telemetry samples

Total system RAM usage that automatically cancels the Bake

Practical: Set this below the point where the OS begins heavy paging. The default leaves headroom for Blender and the solver.
