OTOY Forums

Hi,

This is a beta release of the OctaneRender™ 2020.1 for LightWave™ plugin version 2020.1.0.1, available for LightWave 11.6, 2015.3, 2018.0 and 2019.0/2019.1 Windows x64 and OSX. This build has been compiled using the Octane 2020.1 XB2 core.

To use Octane 2020.1, you need to have a Studio or Enterprise subscription license. We recommend you to update your NVIDIA driver to at least 435.80 for Windows or 435.12 for Linux.

As with all experimental builds, we advise to not to use this release for production purposes. We can't guarantee that scenes saved with this version will be compatible in future releases, and we anticipate there being several maintenance releases.

New features

The features not listed here, like the new universal camera node, will be available in the upcoming builds.

• New option to enable the RTX improvements.
• Spectron Area and Sphere light types.
• New Hosek-Wilkie Spectral Sky Model.
• Improvements to Round Edges artist control.
• SSS Improvements and Random Walk SSS.

- Spectron Area and Sphere light types, added as a new option in the Octane lights.
- New Hosek-Wilkie Spectral Sky Model.
- Improvements to Round Edges artist control.
- SSS Improvements and Random Walk SSS.
- Spectral Hair Material.
- ACES: new workflow and Image Container File Layout

* OCTANE 2020.1 XB2 FEATURES AND BUGS FIXED:
- Added IOR pin to hair material to control the Fresnel effect of the specular reflection.
- Added randomizatoin pins to hair material.
- Added auto bump map support for RTX primitives.
- Added support for UV sets 2 and 3 for RTX primitives.
- Added support for vertex attributes for RTX primitives.
- Added support for vertex attributes for primitives using texture displacement.
- Brought back network rendering (slave are builds available now).
- Primitives using fast rounded edges shader can now be accelerated using RTX.
- Better handling of environment sampling.
- Reduced VRAM used for instancing up to less than half in the most common case.
- Fixed CUDA crash when using turbulence texture in dirt texture.
- Fixed a few issues that would cause the memory usage to slightly increase over time.
- Fixed melanin conversion for inverse reflectance mapping in hair material.
- Fixed secondary bounce rough limit for the azimuthal roughness in hair material.
- Fixed some edge cases where hair material was producing wrong values.
- Fixed auto bump map for projection types other than mesh UV.
- Fixed vertex displacement not being properly applied to primitives using motion.
- Fixed issue breaking some noise functions in OSL.
- Fixed crash while updating a scene and device peering (NVlink) is enabled.
- Fixed issue causing mix material being ignored when it is connected to a layered material.
- Fixed fake shadow being switched off when albedo is greater than zero in universal material.
- Fixed issue that would require unused shared libraries on Linux.
- Fixed issue with AI light when using RTX causing dark renders.
- Fixed issue with volume scattering not rendering as expected.
- Fixed issue when connecting texture nodes to dirt radius input.


Happy rendering,
Your OTOY Team

Material for hair?! ... My God I hope for this everyday....Thank you very much.

Awesome...great...cool.

Sorry, after upgrading to 441 I am still not able to render large scenes.
Rolling back to 431 solves it, and thats renders RTX unusable.
NVIDIA only supplies 431 or 441 on their website. Anyone has 435.8 available?

This is no fun.... half my system will remain barely used (2x 2080TI).

Anyhow, Happy new year for you all!

Hans

Thanks for release Juan, this will make more Bug testing for 2020.x easier now when it's in LW plugin .

Random Walk SSS is pretty cool and easy to use.

Doesn't work, black ipr screen, then Lightwave hangs and dies. Great job!

Have you updated the NVIDIA drivers? Nobody else has reported a problem like that. Do you know if Standalone 2020.1 XB2 works fine in your system?

Thanks,

Latest drivers Jouanjo, as always.

Error log reports:

00:09:47 (0587.68) * OCTANE API MSG: CUDA error 700 on device 1: an illegal memory access was encountered
00:09:47 (0587.68) * OCTANE API MSG: -> failed to load symbol data to the device(kernel data)
00:09:47 (0587.68) * OCTANE API MSG: device 1: path tracing kernel failed

Does that happen for you in every scene or ?

I tested 5 of my older scenes to test RTX speedup and they rendered fine. I use 441.66 studio drivers.

Yep, every scene, old and new.
