Houdini Main Changelogs

Houdini 16.5.442 Updated documentation with information about ramp parameters and new terrain page. Fri. April 13, 2018
Houdini 16.5.442 Float ramps now use interpolation values for points properly. Currently only supporting Constant, Linear, and Catmull-Rom if using the animation curve editor. Color ramps which are drawn as Unity gradients now support Linear and Constant interpolation modes. These are set globally for all points in a ramp, due to the way Unity's gradient works. User can still override interpolation per point via each point's UI field. Fri. April 13, 2018
Houdini 16.5.442 Fixed issue with the Blend COP not loading the blend mask plane parameter correctly in some cases. Fri. April 13, 2018
Houdini 16.5.442 Add missing Nodes section to the Maya Plugin docs Fri. April 13, 2018
Houdini 16.5.441 Deep EXRs now have data window. Default value for "EXR Data Window Planes" is changed from "C A" to "*" so that data window gets computed for all AOVs by default. Thu. April 12, 2018
Houdini 16.5.441 Fixed a bug in the Alembic ROP that caused it to export incorrect transforms for Object subnets in some situations. Thu. April 12, 2018
Houdini 16.5.440 Fixed deadlock when using engine debugger with init scripts that contained python hom calls. Wed. April 11, 2018
Houdini 16.5.440 Fixing the Pxr Mesh Light object to handle scales. Wed. April 11, 2018
Houdini 16.5.439 Fixed a memory leak in COPs when the cook cache filled up to capacity. Tue. April 10, 2018
Houdini 16.5.439 Plugin version 2: Terrain now created for Houdini heightfields with "height" layer. Other layers will be coming soon as well as documentation. Tue. April 10, 2018
Houdini 16.5.439 Fixed unreliable selection of tetrahedrons in the viewport. Tue. April 10, 2018
Houdini 16.5.438 Added support for vertex groups to the Group Create SOP, except for that it doesn't yet support the "Keep by Normals" or "Include by Edges" features. Mon. April 9, 2018
Houdini 16.5.438 Added SOP network tab menu entries for Boolean Intersect, Boolean Union, Boolean Subtract, Boolean Shatter, to make them easier to use from the network editor. Mon. April 9, 2018
Houdini 16.5.438 Updated RMan lights to allow proper scaling. Mon. April 9, 2018
Houdini 16.5.438 The GABC_GEOWalker class can now be used to append new Alembic primitives to a non-empty detail. Mon. April 9, 2018
Houdini 16.5.438 Verbified Volume Rasterize Particles. Mon. April 9, 2018
Houdini 16.5.438 Fixed a UI crash when splitting panes when the split action results in overcrowding of the main window. Mon. April 9, 2018
Houdini 16.5.435 The Alembic HOM Extensions's alembicClearArchiveCache() method now accepts an optional list of archives to clear from the cache. Also, the Alembic Archive Object's "Build or Update Hierarchy" button will now clear the cache before updating the hierarchy. Fri. April 6, 2018
Houdini 16.5.435 Added density, heat & temperature inputs to the pyro shader. This hadn't been done during the conversion from SHOP to VOP node.

The field name parameter on each volume's tab is no longer strictly necessary, but stays for backwards compatibility.

As before, connecting any shader input will still stop automatic binding to density, heat & temperature volumes. With these inputs it is now possible to manually create a bind VOPs for each input, in order to bind to the corresponding volume name.

Fri. April 6, 2018
Houdini 16.5.434 Plugin version 2: Now drawing float ramp parameters as Unity animation curves, and color ramp parameters as Unity gradient. Thu. April 5, 2018
Houdini 16.5.433 Fixed a bug where numeric and string attributes were sometimes being copied via a slower codepath than necessary if the attribute didn't already exist on the destination. This was particularly impactful in cases where a string attribute with all unique strings is copied and then deleted by a single cook. Wed. April 4, 2018
Houdini 16.5.433 Exposed the maximum iterations option for the linear solver inside of GAS Viscosity. High resolution simulations of highly viscous liquids could hit this internal limit and only partially converge to the solution. Wed. April 4, 2018
Houdini 16.5.433 Set 'Apply Sign Fix' in rebuild_surface_volume in the FLIP Solver to be off by default. The signs don't need to be fixed here and the fixing operation is slow. Wed. April 4, 2018
Houdini 16.5.433 Fixed a bug in the crowd solver where enabling the Stick to Deforming Geometry option would cause the active joints of partial ragdolls to be transformed incorrectly. Wed. April 4, 2018
Houdini 16.5.433 Fixed a potential crash when collapsing VOPs into material builder. Wed. April 4, 2018
