Houdini Main Changelogs

Houdini 18.0.310 HDA wrappers of Attribute Paint should correctly reset visualization when they enter the state and leave it. Thu. December 5, 2019
Houdini 18.0.310 Fixed bug with environment map orientation when using .exr files as maps. Thu. December 5, 2019
Houdini 18.0.310 Added an ordered menu to the Attribute Create TOP that can be used to control how the node should handle attribute type mismatches. Previously, the node would always error when attempting to create an attribute with the same name as an existing attribute and a different type. Thu. December 5, 2019
Houdini 18.0.310 Fixed an issue with the way work items copy the frame value from their parent work item. Previously the frame step was not copied, so all work items would have their step size reset back to 1 even if the parent work item had a different step value. Thu. December 5, 2019
Houdini 18.0.310 Fixed several issues with the SOP Import LOP when importing packed disk prims that reference .vdb files or .bgeo files containing VDB primitives. The Houdini geometry file format plugin now supports loading .vdb files, and unpacking USD packed prims that reference a USD Volume prim will now produce that volume's fields instead of empty geometry. Thu. December 5, 2019
Houdini 18.0.310 Fixed rainbow smoke visualization in the viewport. Thu. December 5, 2019
Houdini 18.0.309 TOP Deadline scheduler now supports GPU affinity setting for OpenCL and Redshift nodes. A new GPU affinity Override section on the parm interface provides the functionality to set GPU affinity per job and worker. Wed. December 4, 2019
Houdini 18.0.309 Fixed the hou.Parm.set() and hou.Parm.setPending() HOM methods so that they arguments that are subclasses of one of the acceptable parameter value types (i.e. int, float, str, etc.). Wed. December 4, 2019
Houdini 18.0.309 The Attribute String Edit SOP now supports string array attributes and correctly manages data IDs. Wed. December 4, 2019
Houdini 18.0.309 Fixed bugs where the Promote Invisible Parameters toggle wasn't properly respected when editing parameter interfaces. We now properly support this toggle when promoting the instance parameters of a multiparm. We also no longer follow a channel reference in an invisible parameter to promote a visible referenced parameter. Wed. December 4, 2019
Houdini 18.0.309 Fixed a bug where an HQueue cook would fail if the hip file was opened directly at the root of the drive mapped to HQROOT. (For example H:/test.hip) Wed. December 4, 2019
Houdini 18.0.308 Fixed an issue where the RBD Material Fracture SOP could potentially hang when using the CPU OpenCL driver. Tue. December 3, 2019
Houdini 18.0.308 Add Midpoint hotkey to the Point Weld state RMB menu. Tue. December 3, 2019
Houdini 18.0.308 Fix hou.AdvancedDrawable.setTransform causing the geometry to disappear. The transform is now applied in addition to the translate, rotation, and scale render parameters. Tue. December 3, 2019
Houdini 18.0.308 Fixed an issue with multiparameter instance labels not updating when inserting a multiparameter instance before the end of the multiparameter list. Tue. December 3, 2019
Houdini 18.0.308 Clarified the Invert Filter parameter on the Filter by Expression TOP node. It is now a drop down menu that explicitly describes both operations, rather than a toggle. Tue. December 3, 2019
Houdini 18.0.307 Fixed a bug where the Align Components shelf tool failed with a Python "TypeError". Mon. December 2, 2019
Houdini 18.0.307 The Pyro Post-Process SOP has an option to avoid applying the look or assigning the material if you just wish to process for export. Mon. December 2, 2019
Houdini 18.0.307 Improved the hqueue scheduler submit-as-job UI and added a parameter to customize the job name for same. Mon. December 2, 2019
Houdini 18.0.307 Added a pdg.WorkItem.makeActive() method, which is used in a Python with statement to make a work item active for the duration of the statement. This makes it easier to evaluate multiple node parameters against that work item, or arbitrary Houdini parameters that have expression with PDG @attributes in them. Mon. December 2, 2019
Houdini 18.0.307 Added parameters to enable the data layer server for tractor cooks when using the submit-as-job button from the scheduler. This allows PilotPDG to connect to the cooking TOP job on the farm, using the websocket port which is printed in the log. In the form ws://host:port, using the `remotegraph` TOP node. Mon. December 2, 2019
Houdini 18.0.307 The group drop down on Attribute Paint should properly populate with point groups now. Mon. December 2, 2019
Houdini 18.0.307 Add hou.Geometry.createPackedGeometry() for creating packed geometry primitive. It has an optional point parameter which defaults to None for creating a new point, or if given, use an existing point. Mon. December 2, 2019
Houdini 18.0.307 Fixed an error when running the RBD Grains shelf tool. Mon. December 2, 2019
Houdini 18.0.306 Removed internal "percent" seeding factor in GAS_SeedMarkers. This over constrains reseeding and leads to too few particles being seeded at the liquid surface. A bug when seeding in the boundary layer was also fixed that caused the liquid to be slowly eroded away if the particle birthrate was set too low. Sun. December 1, 2019
