Fixed issues in the Bullet solver where there could be slight differences in the resulting collision shape when a collision shape was recomputed on a later frame. This could occur when resuming a cached simulation, and also affected the guide geometry (convex hulls could appear to have changing topology from frame to frame). These changes may produce minor differences in simulation results.

The installer no longer copies the plugin files to Unreal as Houdini now ships with both v1 and v2. To install the plugin manually. copy the HoudiniEngine folder in the engine/unreal/4.2X or 4.2X-v2 folder to your Engine/Plugins/Runtime folder in Unreal.

Fixed an error in the Python 3 build when opening the node info window for geometry containing volume or VDB primitives.

imaketx will now handle color space of the source images better.

Added a new Circle Spline SOP to allow evaluating and sampling a new type of interpolating spline that is C2, bounded and can form nice circular or elliptical segments.

Added an option to partition sorting that causes work items that are marked as required dependencies to be sorted to the beginning of the partition. If multiple work items are required, they are sorted using the regular sorting options.

Fixed a hang when using the RMB -> Generate Node option on a TOP node with both dynamic and static input nodes, which are in turn connected to the same static processor node

Moved pdg examples from $HH/pdg/examples to $HH/help/files/pdg_examples

Added the FEM Validate SOP. This SOP can be used to inspect tetrahedral or polygonal meshes before running an FEM simulation with these meshes. FEM Validate can be used to visualize the quality of tetrahedra and polygons, and allows poor-quality primitives to be isolated. Inverted tetrahedra can be tracked down as well. This tool uses the same quality criterion that's used by the FEM Solver.
