Pyro

Improved

Fully OpenCL-accelerated pyro pipeline.

RBD

New

New Sleeping Time parameter on the Bullet solver controls how long objects must be below their linear and angular speed thresholds before being put to sleep.

New

New parameters on the RBD Packed Object DOP to use the DOP network’s input geometry and to specify alternate display geometry.

New

New point attributes (accelmax and angaccelmax) can be used to limit the change in velocity from enforcing constraints and collisions.

Improved

Bullet RBD objects collide with the new height field primitives.

Improved

Improved multithreading. For simulations with many separate groups of active objects connected by constraints and/or contacts, the default constraint solver can now solve the constraint groups in parallel.

Improved

When inherit velocity is enabled for animated static objects, the velocity is now transferred when the object becomes active instead of on its first simulation frame. The velocity transfer also now only involves the v and w attributes on the packed primitive’s point - the solver no longer unpacks the geometry to check for additional velocity attributes.

Improved

Improved support for deforming active objects.

Changed

The ODE Solver has been deprecated and will be removed in a future version of Houdini. The Bullet solver should be used instead.

General

Improved

Built-in Intel OpenCL driver with CPU fallback for simulation on the farm.
