OctaneRender 2021.1 for Houdini production build 2021.1.7.0 Tweet

[juanjgon]

Hi,

This is a production release of the OctaneRender™ 2021.1 for Houdini™ plugin compiled with the Octane 2021.1.7 core. This 2021.1.7.0 release is available for the latest Houdini production builds on Windows x64 and Linux gcc6.3.1.

Houdini production builds supported by this release: 18.5.759, 19.0.720, 19.5.368, 19.5.403 and 19.5.435

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 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 2021.1.7.0
=============================================
* PLUGIN FEATURES AND FIXES:
- Plugin updated to support the new Studio+ license

* OCTANE 2021.1.7 FEATURES AND FIXES:
- Fixed a render failure that can happen when you quickly switch between different render targets with a baking camera.
- Fixed render failure when adding a normal texture to an environment texture.
- Fixed uncaught exceptions from OpenVDB, which fixes hang when importing certain VDB files.
- Fixed very slow ray-tracing through some levelset VDBs that are loaded as volume SDF and might result in a kernel timeout.
- Fixed network rendering of volume SDFs.
- Fixed corrupt images when multiple GPUs are compositing different output AOVs at the same time.


=============================================
RELEASE 2021.1.6.0
=============================================
* PLUGIN FEATURES AND FIXES:
- Added H19.0.657, H19.0.720, H19.5.303, and H19.5.368 plugin builds.
- Support of animated attributes while rendering in update scene mode.

* OCTANE 2021.1.6 FEATURES AND FIXES:
- Ported back the improved rendering of hair with motion blur from 2022.1 XB1 to 2021.1.
- Ported back the improved rendering of hair segment joints from 2022.1 XB3 to 2021.1.
- Improved AI light update speed in some corner cases.
- Improved consistency of the amounts of emitter noise between render restarts in scenes with enabled AI light. We now always build the highest quality AI light data structures. This may have an impact interactivity in some corner cases. Let us know if you have a scene where the update speed is severely impacted.
- Fixed a render hang with dirt by limiting the number of surface intersections we allow for a dirt ray.
- Fixed visible seams of adjacent surfaces with different material nodes that have the same settings and also a sub-surface scattering medium.
- Various tweaks and minor fixes in the handling of nested media and dielectrics, especially when a path exits those.
- Fixed Autobump map which when RTX is enabled.
- Fixed render artifacts in custom AOVs when an environment scatter/random walk medium is being used.
- Fixed darkening of custom AOVs of a surface when you change the step length of a volume in front of the surface.
- Fixed bug that caused the full environment to be included in shadow AOVs even when portals are enabled and the environment is not importance sampled.
- Fixed laggy imaging/tone-mapping while rendering is progressing.
- Fixed noise and incorrect background of the position AOVs if RTX is disabled and the scene bounding box has size 0 along one of its axis.
- Fixed post-fx not being shown in the denoised main AOV until denoising has been done.
- OSL: Fixed assignment to short arrays where the index is not a compile time constant.
- OSL: Fixed compilation error with OSL shaders which use escape characters like "\n" and "\t" in string literals.
- OSL: In some cases we fall back to a fixed value if an OSL shader reads an undefined value


Happy rendering,
