Dear Octane community,


OTOY® is proud to announce the availability of the new DCC plugin OctaneRender for Solaris V2021.1.5 - for Houdini 19.0.622.

The world's fastest unbiased GPU rendering engine on CUDA and Metal now integrates completely with Houdini 19.0 Solaris.

What is OctaneRender for Solaris?
The OctaneRender for Solaris plugin is based on Pixar’s USD (Universal Scene Description) and Pixar’s Hydra API to empower artist workflows across look development, scene layout, lighting, and final rendering.

- Please note: OctaneSolaris is merged with the latest OctaneRender 2021.1 for Houdini build 2021.1.5.0 for Houdini 19.0.622, so no need to install the main plugin

-Installation steps-

Insert the OctaneRender® plugin folder path to the houdini.env file. Houdini®creates this file after launching it for the first time.
On Linux and macOS® systems, append a single line to enable OctaneRender®:

HOUDINI_PATH = "/path/to/octane;&"

On Windows® systems, you need to set the PATH to point to the plugin bin folder as well:

PATH = "C:/path/to/octane/bin;$PATH"


Setting this environment variable outputs any error related to loading the OctaneRender® plugin on the command line for diagnosing installation problems:
HOUDINI_DSO_ERROR = 2

-Houdnin Packages/json installation steps-

- Please create a folder inside Documents\houdini19.0 and name it as Packages
- Open notepad or any text editor and use these lines - Then Save as OctaneSolaris.json
- Please make sure to disable the .env paths

New features
To learn more about the new features and improvements of OctaneRender 2021.1.3, please check out the 2021.1.1 release post


- Changes since 2021.1.4 - 05 10 22[Test]-

• - Compiled with latest OctaneRender for Houdini 2021.1.5.0
• - Implemented "displayColor" for vertex color
• - Fixed Focal length
• - Fixed crash changing material while the IPR session is running (When a material is edited, it gets deleted by Solaris via Hydra so it requires reloading the scene)
• - Fixed Enable environment medium toggle

-Known Issues-
- Octane Color response is disabled because Hydra buffer expects linear output
- Light Linker is yet to be supported as we are investigating if we could assign the Octane light IDs internally.
However, the usual Octane light linking works as expected.

Volumes are not rendering.

I tried both vdb and standard houdini volumes. It shows up in Karma.

Hi Rohan,

Thank you so much for reporting this issue.
Unfortunately, we are unable to get volume data instead Houdini generates only points, velocities, and widths which implies it is pointing (particles) primitive.
We assume that the rest are proprietary values created by Houdini for Karma render.

The only workaround, for now, is to write out as vdb sequences then import in LOP as Volume.

Please note Octane volume settings are under the "Render Geometry settings" node.

cheers

I noticed this plugin is still Windows-only. Are you planning to start releasing Linux builds as well?

Hi mzo,

Thanks for the post.
Yes, we are planning to start releasing Linux builds and other Houdini versions once it's a little stable.

cheers
