OctaneRender 2020.1 for Houdini Beta build 2020.1.0.1 XB2 Tweet

[juanjgon]

Hi,

This is a beta release of the OctaneRender™ 2020.1 for Houdini™ plugin compiled with the Octane 2020.1 XB2 core. This 2020.1.0.1 release is available for the Houdini 16.5/17.0/17.5/18.0 latest production builds on Windows x64, Linux gcc6.3.1 and MacOS 10.12. This plugin is also compatible with Houdini Indie (While working inside the Indie version, the plugin will have a 4k limited resolution while rendering sequences and the scene export and cloud rendering features disabled)

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
To learn more about the new features and improvements of OctaneRender 2020.1, please check out the 2020.1 XB1 release post, but this is a quick list of the main new features that have been added. 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.
• Particle Point Attributes.
• 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
• Volume Step % and Shadow Step %
• Volume Sample Position Displacement
• New Universal Dirt System

Release Notes
=============================================
RELEASE 2020.1.0.1
=============================================

* OCTANE FEATURES AND BUGS FIXED:
- Added Linux and MacOS builds.
- 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

Network options window doesn't show my slave... Is this disable for Indie users?

Nope, the plugin while working with Indie doesn't have any restriction related to the Octane native network rendering. Are you sure that you have both the XB2 plugin in your system and the XB2 slave installed in your network node?

Thanks,

muchas gracias Juan!

Hi,
There is a significant difference between the way the render looks with RTX on as opposed to being disabled. Is that something expected or due to still being in experimental phase?

Thanks

Yes, I suppose that there are still features that must be improved on the RTX side. If you can reproduce these problems exporting the scenes to Standalone and you post them in the general forum, it could help the core devs to fix all these limitations or rendering differences.

Thanks,

Hello, I'm trying to test this release on my Macbook pro, my graphics are Radeon Pro 555X 4GB and intel UHD Graphics 630 1536 MB
is this supported? because I don't have GPUS available on the Octane settings, thank you.

Nope, sorry. This build is only compatible with NVIDIA GPUs. The MacOS Metal based Octane builds are not available yet.

Hello!

I was testing the displacement and i noticed that with the RTX on the shadows are not calculated.

In the standalone version, however, everything works correctly.

Using the same XB2 Standalone? This is really weird. Can you share a test scene to check it here?
