Houdini Main Changelogs

Houdini 17.0.486 Fixed a bug that caused some tools to ignore volatile component selections made before invoking the tool. Also fixed a bug that could result in a crash when using volatile states in multiple viewports. Thu. February 7, 2019
Houdini 17.0.486 Added an option to the houdiniInputGeometry node to allow creating groups for facetOnly sets Thu. February 7, 2019
Houdini 17.0.486 Fixed a possible crashing bug in VEX when dealing with nested structs and conditional statements. Thu. February 7, 2019
Houdini 17.0.485 Added method to delete a group from the input geo bumped Hapi API version to 37 Wed. February 6, 2019
Houdini 17.0.485 Fixed an issue with the Retime SOP that would cause it to remain in an error state when its input failed to cook, even after a frame change that should not result in an error. Wed. February 6, 2019
Houdini 17.0.485 Fixed a couple issues in the crowd solver that prevented arcing clips from being applied to parented agents, and could also produce unexpected results when e.g. dynamically parenting an agent during the timestep. The 'agentturnrate' point attribute is now set for child agents, and their transforms are also now updated at each substep to match the behaviour of normal unparented agents. Wed. February 6, 2019
Houdini 17.0.485 Fixed a bug where user functions which modified arguments in VEX weren't properly tracking modifications when the function was called as an import shader. Wed. February 6, 2019
Houdini 17.0.483 Unity plugin: Instanced objects now have their transform combined with their source prefab transform. Originally the point transform overrode existing Unity's transform. Mon. February 4, 2019
Houdini 17.0.483 Fixed "Update Input Landscape Data" not working properly with object merge inputs. Mon. February 4, 2019
Houdini 17.0.483 Fixed the density attribute painting button on the Hair Generate object. Mon. February 4, 2019
Houdini 17.0.482 Fixed a viewport bug with SOP guides sometimes refusing to update. Sun. February 3, 2019
Houdini 17.0.481 Agent base discs now properly display when the viewport is in Z-up mode. Sat. February 2, 2019
Houdini 17.0.480 Fixed bugs homing/framing with objects using point or dop instancing. Fri. February 1, 2019
Houdini 17.0.480 Agent Procedural no longer changes names of objects when rendered with verbosity level above 1, which could affect trace scopes and cryptomatte name layers. Fri. February 1, 2019
Houdini 17.0.480 Attempting to add a primitive intrinsic with VEX (which should do nothing) will no longer crash. Fri. February 1, 2019
Houdini 17.0.480 Fixed a crash that could occur when disabling and then re-enabling a SOP solver. Fri. February 1, 2019
Houdini 17.0.480 Fixed a bug in UV Layout where reuse of trapped area under packed islands omitted the padding on the top side of the cavity. Fri. February 1, 2019
Houdini 17.0.479 Limit the skinshadercore VOP to being used in the surface context.

This should fix any errors and warnings related to the contents being included in displacement shaders. It was previously possible for this to happen when the VOP was assigned as a shader directly, without explicitly piping into a surface outputs VOP.

Thu. January 31, 2019
Houdini 17.0.479 Fixed bug where changing levels in the viewer would cause an older state to be entered rather than the last one the viewer was in at that level, introduced in 17.0.421. Thu. January 31, 2019
Houdini 17.0.478 Fixed errors with the attribute dropdown menus and paint buttons on the Guide Groom and Hair Generate objects. Wed. January 30, 2019
Houdini 17.0.478 The Hairgen SOP now takes into account primitive list data ids when checking for input changes.

It also no longer warns about missing guide attributes when there are no guides.

Wed. January 30, 2019
Houdini 17.0.478 Fixed a packed primitive crash in the viewport during an incremental update after revisiting a SOP which previously displayed it. Wed. January 30, 2019
Houdini 17.0.478 Fix missing data dependencies in the View Dependencies dialog for VEX and Python nodes. Wed. January 30, 2019
Houdini 17.0.478 Image plane using Light Path Expression can now store unshadowed lighting contributions by prefixing the expression with "unoccluded;" token. Wed. January 30, 2019
Houdini 17.0.478 Tetrahedrons will now be deleted if all their points are deleted. This means a blast or delete sop on a point group will remove both the points and tetrahedrons if they are entirely contained in the group, as is the case for other primitive types. Wed. January 30, 2019
