What's New in Dynamics and nDynamics


nHair improvements


Simulate nHair on nCloth objects

Workflow improvements now make it possible to create nHair systems on deforming nCloth objects. With full two-way interactions between colliding hair curves and nCloth surfaces, you can combine nHair and nCloth to create realistic fur coat simulations, furry creatures and more.

Performance improvements

A new Disable Follicle Anim attribute lets you playback simulations without evaluations on hair follicles. This improves simulation performance especially for hair systems with large numbers of animated follicles.

Collide with mesh

When you create nHair, you can select a new Collide with mesh option that automatically converts the assigned mesh to a passive collision object. Collide with mesh also creates internal connections between the hair system and the Nucleus solver so that the solver has information about the follicle positions at the start frame of the simulation.

Collide with mesh provides performance improvements when simulating nHair on animated surfaces.

Delete Hair

A new Delete Hair option lets you remove selected hair curves and Paint Effects hair without deleting other hair system nodes.

New Component nConstraint


A new Component nConstraint provides additional control of stretching and bending behavior of nCloth meshes. Component constraints let you select mesh edges and faces, then adjust stretch or bend resistence in these areas of the cloth.

Use Component nConstraints to simulate elastic bands in clothing, stiff collars on shirts, natural-looking pleats in skirts, and more.

Component nConstraints can only be used with nCloth objects.

Fluid Effects additions


Fill Object Volume

A new Fill Object Volume attribute extends surface emission options by letting you emit fluid into the volume of selected geometry.

Start Frame Emission

With new Start Frame Emission attributes, you can start fluid emission at advanced frames of your simulation without setting an initial state. These attributes also make it easy to create bursts of emission at start frames.

Redesigned nDynamics object icons


Freshly redesigned icons for nDynamics objects make it easier to identify Nucleus objects, dynamicConstraint nodes and nHair follicles in the Node Editor or Outliner.

New mcx cache format

Create larger nCache files with a new mcx cache file format. Use this new format to save data heavy simulations, such as high resolution Fluid Effects, in files that can exceed 2.0 GB. Previously, nCache files were limited to 2.0 GB.

When creating an nCache (nCache > Create New Cache and Fluid nCache > Create New Cache), select the mcx file format to take advantage of the larger cache file sizes.

Input Attract Method

A new Input Attract Method improves performance by letting you specify which vertices of an nCloth mesh participate in simulations.
