SideFX has released Houdini 18.5.351, the latest update to its procedural toolkit. The 18.5 release adds a number of features, including new cloth and fluid simulation tools, also updates the Solaris shot layout and look dev toolset, Karma renderer, plus game development plugins.

- 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.
- The FEM Hybrid Object can now be used to simulate isolated points (Particle tab) and polylines (Rod tab). This is in addition to the current support for tetrahedra and (closed) polygons. A single FEM Hybrid Object may have all these primitive types in it simultaneously.
- Added the FEM Slide Constraint. This constraint can be used to stick points of one object to the surface of another object while allowing sliding to occur between the point and the surface. This constraint can be applied between an FEM Object and a Static Object, between a pair of FEM objects, or between distinct connected components of a single FEM Object.
- Added the FEM Attach Constraint. This constraint allows you to attach an FEM object to another FEM object, attach an FEM Object to a Static Object, or attach distinct connected components of an FEM Object.
- Fixed an issue with TOP Geometry networks not recooking when the displayed node inside the network is changed.
- Added "burn" as a source option to the Pyro Source SOP. The SOP also has an initialization script for sourcing burn now, and the initialization menu has a default option to ensure that the callback is always invoked. Order of entries for Attribute and Initialize menus has changed, though old labels are unaffected.
- Fixed various bugs that caused drag-and-drop from external applications to fail. The bugs mostly occurred on Windows.
- Renamed UI_EventHandler to UI_OHEventHandler and UI_TriggerObject to UI_OHTriggerObject.
- Fixed the Origin Axes draw mode for USD primitives in the LOP viewer.
- Karma now handles asset paths as primvars when binding to VEX variables.
- Bumped HAPI version to 3.5.0.
- Populate the PDG Path Map Zones combo box with POSIX and WIN since those are the defaults.
- Fix the definition of the KarmaAOVSettingsAPI schema. The attribute names in that schema didn't match the attributes being set by the Render Var LOP.
- Reduced lag when manipulating objects in IPR.
- Fixed issue with setting metadata when the value did not exactly match the type specified in the schema.
- Fixed a LOPs viewer bug where the scene could appear ghosted after diving in and out of a SOP Create/Modify LOP.
- Fixed LOP viewer refresh issues when splitting the view into multiple viewports and returning to the LOPs viewer when a renderer is active.
- Fixed a crash in the Extract Transform SOP when the input geometry was empty.
- Fixed code localization in commandchains to use pdgcmd.localizePath, which ensures that backslashes are converted to forward slashes to avoid parm evaluation errors when an $HQROOT-based path is used with UNC shared root folder.


Houdini is a 3D animation and special effects application developed by Side Effects Software, a twenty-five-year-old company based out of Toronto. Houdini was designed for artists working in 3D animation and VFX for film, TV, video games and virtual reality. Houdini brings these worlds together into a single powerful platform.
Side Effects' former flagship product was PRISMS, a suite of 3D graphics tools that served as the basis for the development of Houdini.[/center]
