Hi,

This is an production release of the OctaneRender™ 2020.2 for LightWave™ plugin version 2020.2.3.0, available for LightWave 11.6, 2015.3, 2018.0, 2019.0/2019.1 and 2020.0 Windows x64 and MacOS (CUDA). This build has been compiled using the Octane 2020.2.3 core.

Make sure to use an NVIDIA Studio driver with version at least 456.38 on Windows or 455.23 on Linux to use this version. No driver updates are required for macOS 10.13 (CUDA).

New features
To learn more about the new features and improvements of OctaneRender 2020.2, please check out the 2020.2 release post, but this is a brief list of the main new features that have been added.

FEATURES AVAILABLE IN THE LIGHTWAVE PLUGIN:

• Improved RTX performance.
• Fast Spectral Nested Dielectrics.
• Denoiser support for the new NVIDIA Ampere devices.
• New chaos texture node.
• Improved color correction node.

FEATURES STILL IN DEVELOPMENT:

• ACEScg and filmic processing. New color options available in the Octane ROP node.
• OpenColorIO Management, Display and Export (OCIO profile). Configured from the "OCIO" environment variable.
• OpenColorIOColor graph nodes. Look, Profile and View nodes
• Integrated multi-scatter from volumes or surfaces. Available in the Octane OBJ spare parameters.
• User generated compositor AOV passes for combining render and light passes in full a compositor node graph.
• Null material.
• Spotlight texture.
• New ray type, texture composite and channel tools shader nodes.

Release Notes
=============================================
RELEASE 2020.2.3.0
=============================================

* PLUGIN FEATURES AND FIXES:

- Multi-thread scene extraction. New option in the plugin options panel to enable/disable this feature. This feature is limited to 64 cores, or to a single CPU in dual-CPU systems with more than 64 cores. The F9/F10 preview window will be frozen while processing the scene extraction.
- Fixed a problem with the chaos texture transformation parameters.
- Fixed a crash while working with objects whose name starts with "("

* OCTANE FEATURES AND BUGS FIXED:

- Brought back the dialog that allows retrying activation when the connection with OctaneLive has failed.
- Fixed bug causing moving instances to disappear when subframe start would be set to 100% in the animation settings.
- Fixed crash when an OSL shader has two outputs.
- Fixed crash when an OSL shader has a struct as input parameter.
- Fixed render failure when rendering a preview of a toon material.
- Fixed render failure when texture displacement is used on a mesh with no UV coordinates and RTX is enabled.
- Fixed AI denoiser on macOS by updating cuDNN to version 7.6.5.
- Fixed volumetric spot light cutting out geometry with a material priority less than 0. This is because the volumetric spot light had a default priority of 0, so if the user tries to set the scene geometry with less than 0 priority, they will be cut out.
- Fixed rendering of fake shadows of nested dielectrics that have SSS.
- Fixed missing attenuation if a toon material is indirectly visible, e.g. behind some tinted glass.
- Fixed material opacity not using the correct opacity when using mix material inside a layered material node.
- Fixed incorrect reset of material layers if a mix material gets changed and is used inside a layered material node.
- Fixed incorrect rendering of Vectron nodes with object layer / material map nodes if connected to an OSL texture with an _sdf input.
- Improved performance in some scenes with a scattering environment medium when using RTX.
- Fixed portal material being non-transparent to shadow rays.
- Fixed clamping of HDR input values in the color correction texture.
- Fixed CUDA failure when rendering toon materials.
- Fixed incorrect rendering of toon materials with opacity < 1.
- Fixed CUDA failure when vertices of a mesh are moved around in quick succession and RTX is enabled.
- Fixed broken auto bump of vertex displacement if dirt is used in the material as well.
- Fixed missing render update if a toon ramp is modified.
- Fixed superfluous geometry updates when an input of a volume node got changed.
- Fixed specular transmission "leaking" into the indirect reflection render pass.


Happy rendering,
Your OTOY Team

Any benchmark about the multi-thread scene extraction time improvements while working with large production scenes is welcome

Thanks,
-Juanjo

Thanks!!!! This multi threaded extraction is something that takes things to a new level. It will save hours. Great job.

Well done Juan, you know my results but just for sake of conversation here, I have 3-5x speedup in midsize scenes and some scenes even 10x due many cores CPU now finally doing some work .

Great work, thank you for your effort this is game changer for LW scene extraction waiting/times.

thanks Juanjo¡

Excellent thank you

Thank you very much for one more update Juanjo.

Sorry for my ignorance.

What does (Priority) do in the Transmission / Misc tab?

I did not have the opportunity to check if this function came out in previous versions or in this one.

Grateful.

Thank you for the update.
Unfortunately the Multi-thread scene extraction crash my LW immediately. It isn't a big problem for me, my scenes aren't so fat and I can disable it. In any case I ask if it is only a my problem or if it happens to someone other.
I know, it is my fault, I still working on W7 so I can use only game driver, but maybe this isn't a problem of nvidia driver, but SO.
Bye
Gianluca

Thanks for new release. But I also got crashes, but not only with this function enabled - many of my scenes that ran without problems on the previous release now regularly crash.

Test uses a single 16k rasterized LW procedural as well.

Old Octane opening IPR for my heavy DDG ship scene: 4min 25s. New Octane:28s.

F10: 2m 6s. New Octane:28s

Holy Hotness! And yeah, frame to frame all cpu cores are jamming now.
