Houdini Main Changelogs

Houdini 16.5.460 Fixed bug with photon map lookup where if the photon map name was varying over VEX processors or bound to a geometry attribute, the wrong map could have been used. Tue. May 1, 2018
Houdini 16.5.460 Modified the Python error dialog for HOM event loop callbacks so that it is modeless. Tue. May 1, 2018
Houdini 16.5.459 Fixed applying HDA to the current selection not working properly with object path parameter inputs, or with assets that successfully cook without inputs. Mon. April 30, 2018
Houdini 16.5.459 Fixed a regression in Bullet 2.86 that caused initially overlapping concave or box shapes to be incorrectly handled by the solver. Mon. April 30, 2018
Houdini 16.5.459 Add new hou.ScriptEvalContext class which allows one to manually redirect which node and parameter gets used for resolving relative paths and data dependencies. This allows one to properly wrap a Python SOP inside an HDA that references code from a top level parameter. Mon. April 30, 2018
Houdini 16.5.459 Fix HOM bug in hou.evaluatingParm() where it would report None when evaluated from a backtick pythonexprs() hscript expression. Mon. April 30, 2018
Houdini 16.5.459 Fixed a bug in the RBD Packed Object DOP where, if Inherit Pivot from Point Position was enabled, the (disabled) Pivot parameter's value was used instead of the correct pivot when applying the transform parameters on the Initial State tab. Mon. April 30, 2018
Houdini 16.5.457 Volume Splice SOP (and hence the HeightField Tile Splice) would encounter round off errors that would cause it to fail to splice aligned boundaries. For height fields, this would cause resampled tiles to sometimes completely fail to splice. Sat. April 28, 2018
Houdini 16.5.456 Fixed Houdini from crashing on startup when launched on macOS 10.10 and 10.11 machines. A previous fix for the crash committed in 16.5.351 was ineffective. Fri. April 27, 2018
Houdini 16.5.456 Fixed crash on macOS 10.11 with Houdini Engine when a new out-of-process session is created. Fri. April 27, 2018
Houdini 16.5.456 Fix crash when deleting compiled shaders whose child nodes have references to the toplevel parent. Fri. April 27, 2018
Houdini 16.5.455 The Gas Resize Field will now snap multiple fields to be exactly aligned if they are within floating point of being aligned. This avoids fields drifting apart if they start off slightly unaligned. Narrow Band FLIP was creating a slightly misalligned surface field which would drift and for some configurations, eventually lead to a crash. Thu. April 26, 2018
Houdini 16.5.455 Fixed subtle bug with bundle expansion that was extremely rare. Thu. April 26, 2018
Houdini 16.5.455 Fixed a bug where writing Crytomatte layers into same file as the beauty pass could lead to corrupt output if the data windows mismatch (which could commonly happen when using matte shader). Thu. April 26, 2018
Houdini 16.5.455 Fixed problems where the Capture Geometry tool would erroneously restart immediately after finishing a capture. Thu. April 26, 2018
Houdini 16.5.455 Fixed a bug where matte shading opacity was erroneously affected by fake caustics. This bug was introduced in 16.5.275. Thu. April 26, 2018
Houdini 16.5.454 Added operator chooser button to the Bone Capture, Capture Meta, and Capture Correct SOPs, and the Handle and Spatial Audio CHOPs. Wed. April 25, 2018
Houdini 16.5.454 It's now possible to have multiple GI lights enabled at the same time. Wed. April 25, 2018
Houdini 16.5.454 Fixed a flipbook crash when an error or warning was generated during flipbooking. Wed. April 25, 2018
Houdini 16.5.453 Fixed a bug where hython executed the 123.py default scene script even when it was passed a .hip file argument on the command-line. Also fixed a bug where hython executed the 456.py post load script an additional time when it was passed a .hip file argument on the command-line. Tue. April 24, 2018
Houdini 16.5.453 Fixed a bug where DCMs may store wrong zback values, leading to incorrect visuals and worse compression. This bug was introduced in 16.5.366. Tue. April 24, 2018
Houdini 16.5.453 Plugin version 2: Updated documentation with new section on Painting and Editing attributes. Added option to show only editable node's geometry for Editing Attribute tool. Tue. April 24, 2018
Houdini 16.5.452 Plugin version 2: Painting attributes tool has been significantly improved. Editing attributes tool is now fully complete. Documentation will be updated soon. Mon. April 23, 2018
Houdini 16.5.452 Fixed a bug where hou.GeometryViewport.changeType() would change the viewport type, but not actually change the view. We now attempt to restore a stashed view for the new type, and failing that, home the viewport. Mon. April 23, 2018
Houdini 16.5.449 Fixed an issue where the collision radius of a cloth object would not be properly applied when it collides with a volume or a ground plane. Fri. April 20, 2018
