Hi,
This is a production release of the OctaneRender™ 2021.1 for Houdini™ plugin compiled with the Octane 2021.1.1 core. This 2021.1.1.2 release is available for the latest Houdini production builds on Windows x64 and Linux gcc6.3.1.
Houdini production builds supported by this release: 17.5.460, 18.0.597, 18.5.759, 19.0.383, 19.0.455 and 19.0.498
This build includes the first beta version of the new Qt5 IPR Window, the core of the plugin's whole new IPR system that will replace the old OpenGL IPR Window. There are still some important features missing (like render region, camera selector, shortcuts/preferences, background image, or snapshots gallery) that will be added this year, alongside the viewport IPR rendering feature, but the core technology is ready to be tested. The new Qt5 IPR window is available for both Windows and Linux (and macOS in the future) and it can be opened as a floating window or inside a Houdini pane.
This version supports Nvidia Ampere GPUs and as a consequence, we had to drop support for old Kepler cards with a compute model < 3.5. And please make sure to use a NVIDIA Studio driver with version at least 456.38 on Windows or 455.23 on Linux

Release Notes
=============================================
RELEASE 2021.1.1.2
=============================================
* PLUGIN FEATURES AND FIXES:
- Fixed an IPR crash after adding popnet nodes.
- Fixed a crash while rendering scenes with several spectron lights.
- Fixed a problem in the render target HDA related to the daylight texture environment transformations.
- Added H19.0.498 plugin build.
- Added basic support for the bypass flag to the Octane VOP nodes.
=============================================
RELEASE 2021.1.1.1
=============================================
* PLUGIN FEATURES AND FIXES:
- (BETA) Qt5 based IPR window system.
- Hair rendering points width lower limit updated to 0.000001 units.
=============================================
RELEASE 2021.1.1.0
=============================================
* PLUGIN FEATURES AND FIXES:
- Added H18.5.759 and H19.0.455 plugin builds.
- Addressed a problem while creating VOP texture nodes with the IPR enabled.
- Fixed a problem in the render target HDA related to the volume AOVs.
- The Octane material builder node is now created including the Octane universal material node inside.
- Updated the defaults of some ROP parameters to match the most common production settings.
- New option in the OBJ spare parameters to ignore the pivot point attribute, enabled by default to resolve xform problems with the packed geo instancing.
- Fixed a problem in the hair rendering with very low "width" point values < 0.0001
- Added support for custom object AOVs.
- Added the "Cinema 4D Noise" shader node.
- Refactoring of the Cryptomatte AOVs to support material and object IDs from the Houdini node paths, custom OBJ IDs and layer/instance IDs.
- Refactoring of the scene cleaning code to hopefully fix some rare crashes while rendering sequences in full scene reload mode.
* OCTANE 2021.1.1 FEATURES AND FIXES:
- Added Cryptomatte AOVs for mattes based on the render layer, user instance ID and geometry node name of an object.
- Brought back the option "Emulate old volume behaviour" to the kernel nodes.
- Added a small offset to cell noise and the checkerboard texture to avoid artefacts on axis aligned planes that lie exactly on the face of a checkboard / cell cube.
- Overhauled the way how render work is distributed to local and remote GPUs: The main idea is to reassign already assigned but unfinished work to available GPU when there is no more unassigned work left. This avoids that net rendering may hang due to unfinished work, because some intermediate result got lost. It may also reduce the render time when the local GPUs are out of work but Octane is still waiting for one or more render nodes to finish and return their result.
- Fixed clipping material that is a vectron mesh not working correctly as it casts shadows over other materials its clipping.
- Fixed emission with "Visible on diffuse" disable still being visible on universal materials with a coating.
- Fixed render failure on render nodes if AI light is enabled for sphere light primitives.
- Fixed render failure in scenes with mix materials when clay mode is enabled.
- Fixed render hang if you use an environment texture that uses the "Sample position" texture and if "Importance sampling" is enabled.
- Fixed render failure when you use a texture with projection "Sample pos. to UV" for vertex displacement.
- Fixed light linking through transparency surfaces giving unexpected results.
- Fixed incorrect Vectron® bounding boxes if there are object layer maps in the node tree.
- Fixed noise pass not applying gamma when an OCIO view is selected.
- Fixed denoiser not working on CPUs without AVX support.
- Fixed mismatch between the main AOV with post FX enabled and the composite of the main AOV with the post-processing AOV.
- Fixed failure to write OpenEXR files to paths that contain characters that are not in the current ANSI code page.
- Fixed render timer not starting if no local GPUs are used for rendering.
- Fixed the cuDNN download for the demo version on systems that didn't run OctaneRender before.
- OSL: Fixed raytype("shadow") for volume scattering and absorption textures.
- OSL: Fixed referencing of vertex attributes via unconnected OSL input variable.
Happy rendering,
Your OTOY Team
