OctaneRender 2023.1.0.3 Solaris19.5.805&20.0.547RC5-obsolete Tweet

[BK]

OTOY® is proud to announce the availability of the new DCC plugin OctaneRender 2023.1.0.3 Solaris 19.5.805 - RC5 and Solaris 20.0.547 - test.

The world's fastest unbiased GPU rendering engine on CUDA and Metal now integrates completely with Houdini 19.5 & Houdini 20.0 Solaris.

What is OctaneRender for Solaris?
The OctaneRender for Solari's 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.

-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\houdini19.5 and name it as Packages
- Open notepad or any text editor and use these lines

Code: Select all

{
    "enable" : true,
    "env":
    [
        {
        "OCTANE_AUTOSPAREPARAMS" :
        {
            "value": 1,
        },
            //location to your octane folder (example below)
            "OCTVERSION": "PATH\TO\OCTANESOLARIS\Win64FOLDER",
        },       
     
        {
            "HOUDINI_PATH" :
            {
                "value": "$OCTVERSION",
            },

            "PATH" :
            {
                "value": "$OCTVERSION/bin",
            },
            "PXR_PLUGINPATH_NAME" :
            {
                //if you have the Solaris version installed
                "value": "$PATH\TO\OCTANESOLARIS\dso\usd_plugins",
            },
        }
    ]
}

- 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 2023.1.1 and the Render Node app, please check out the 2023.1.1 release post


- Change log since last release[Test]-

• - Merged with OctaneRender 2023.1.0.3 (viewtopic.php?f=102&t=82800)
• - Improved Octane AOV node
• - Fixed missing Octane Materials and texture nodes wired onto Octane composite material
• - Fixed *material not found* error with Demo builds
• - Fixed an issue with the ray precision

https://www.sidefx.com/docs/houdini18.5 ... mport.html

-Known Issues-
- Solaris rendering extra beauty AOV with Octane node and currently investigating
- 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.
- Deep AOV is yet to support!


Important: if using macOS, we strongly recommend that you update to version 13.3..

Linux Note
On Linux only compatibility Houdini 20 build is supported (gcc9.3).
It can only be installed by downloading it from the downloads page since it's not visible in the Launcher:
https://www.sidefx.com/download/daily-b ... ction=true
or direct download link: houdini-20.0.547-linux_x86_64_gcc9.3.tar.gz
We are looking into supporting the gcc11.2 build.

Thanks for this!

Question, how do you render the H20 ocean procedural with Octane? I get the displacement but no matter how I try to feed it octane shaders it won't render or work, just renders white.

Hi snakeboxmedia,

The procedural ocean would work properly once we have MaterialX implementation into our engine..

Thank you for this update.
I have tackled two issues that need addressing:
1) In Octane render settings, there's an option for a "Dome Light" and an option for "HDRI". If "HDRI" option is selected without having a Houdini "Dome Light" node connected to the USD network the lighting is off and doesn't work properly.
2) In the Octane Material Builder inside a "material library", the "Texture Image RGB" node(maybe also other texture nodes) doesn't process the "Color space" and the "Legacy gamma" options.
* I have attached two screen shots for clarification.
* I'm using Houdini 20.0.547 - Python3.10

You should probably change the names of the material hdas because now you can't differentiate them.

Hi,

Is there any work around for hair render inside Solaris ?
I want to use procedural hair system so I have been trying to get the hair color from image texture loaded with "Attribute from map" passing to Cd.
However, when I put "displayColor" with the node Vertex Color Attribute, plug into albedo, nothing happened, just plain white color show up for the hair.
Everything work perfectly at SOP level just not in Solaris.

Hi EyasArraf,

Thanks for the feedback.
1) In Octane render settings, there's an option for a "Dome Light" and an option for "HDRI". If "HDRI" option is selected without having a Houdini "Dome Light" node connected to the USD network the lighting is off and doesn't work properly.[/b]
- Would you please share or PM the render result?
For the "Dome Light" setting workflow Houdini uses the Gamma value as 1 and for the "HDRI" we use the Gamma 2.2. Please try setting it to 1 and see if the lighting matches.

2) In the Octane Material Builder inside a "material library", the "Texture Image RGB" node(maybe also other texture nodes) doesn't process the "Color space" and the "Legacy gamma" options.[/b]
- It seems to be working fine on our side. Maybe you could check by enabling the **Show Octane Window** from the Octane Settings>Tools. And then change the Color space from Texture Image RGB node.
If this does not work then please attach your scene including the texture.

cheers

Hi galleon27,

Thank you for your suggestion.
We have requested our dev if we can rename one of the Material Builders.
For now, please edit the Octane Solaris Material builder from the Type Property.

Hi hoang_anh_,

Thanks for the post.
It looks like Houdini has a Basis Curves primitive which gives access to optional color and other parameters. The other way to do it is to have primvars with colors along each curve.
Would it be possible to share a sample scene for us to investigate?


cheers
