nParticle performance improvements
Additional Nucleus solver threading improves the performance of nParticle collision detection, making large nParticle simulations faster particularly when Enable Liquid Simulation is on, and when nParticles are colliding with other Nucleus objects.
New Local Force and Local Wind attributes let you apply gravity and wind to individual nParticle objects. These forces are applied locally and do not affect other Nucleus objects that are assigned to the same solver.
Particle color emission enhancements
You can now use the Texture Emission Attributes, such as Inherit Color or Inherit Opacity to color particles emitted from all emitter types. In previous versions of Maya, these attributes can only be used with Surface emitters. To use Inherit Color or Inherit Opacity, you must disconnect the corresponding internal shading ramp from the nParticleShape node. To do this, in the Per-particle (Array) Attributes, right-click on the per-particle attribute, and select Break Connection.
These enhancements are also supported by Maya classic particles.
