OctaneRender 2020.1 for Houdini Beta build 2020.1.0.2 XB3 Tweet

[juanjgon]

Hi,

This is a beta release of the OctaneRender™ 2020.1 for Houdini™ plugin compiled with the Octane 2020.1 XB3 core. This 2020.1.0.2 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 and Curves 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 2020.1.0.2
=============================================

* PLUGIN FEATURES AND FIXES:
- Addressed some error messages reported by the volume nodes while cleaning the scene.
- Improved .orbx proxy code to support more .orbx file types.

* OCTANE 2020.1 XB3 FEATURES AND BUGS FIXED:
- Added float and color attributes support for hair primitives.
- Added ability to hide specific objects from being evaluated by dirt.
- Memory optimizations when using the built-in denoiser.
- Minor performance improvements for hair and displacement geometry.
- Fixed 100% transparent object casting shadow on a SSS material.
- Fixed issue causing dirt to work just with the bottom level material when using composite materials.
- Fixed issue causing some scenes using autofocus with RTX to miss some geometry.
- Fixed GPU illegal memory access increasing shutter time from zero when using RTX.
- Fixed network rendering when the master runs on OSX and uses either Windows or Linux slaves.
- Fixed GPU invalid memory access when using auto-bumpmap with RTX geometry.
- Fixed issue causing geometry to disappear when using a baking camera after switching render targets.
- Fixed albedo for hair when the intersected primitive is not a hair primitiv.
- Fixed potential cause for artefacts in pixels which rays would be coplanar to quad primitives.
- Fixed issue in the way memory usage was tracked showing it continuously increasing.
- Fixed issue with auto bump map which was not working properly on the universal material layers.
- Fixed issue in auto bump map's plane size calculation which was causing wrong results.
- Fixed issue that was causing geometry to disappear when using a displacement texture with zero height.
- Fixed scenario in which auto bump would produce results hardly noticeable.
- Fixed crash when using some OSL shaders including some OSL geometry.
- Fixed issue causing full rebuilds after updating scatter nodes.
- Fixed incorrect light sampling when using a a mix of RTX primitives and other primitive types.



Happy rendering,

Color attributes for Hair works kinda but there are bugs. Looks likes it inverts the colors.

EDIT1: Ignore this for now. It seems its a problem with my setup cause it works fine on some other example i did. Needs further testing i guess.

EDIT2: Ok so, after further testing i've come to the conclusion that there are bugs. Some parts are fine and some are incorrect as you can see in the attached image (TEST_003)
in the examples TEST_001 and TEST_002, the bug happened when i tried to do a gradient.

Can you share your test scene to take a look at it here?

Thanks,

Here you go. Btw it works just fine in standalone.

Thanks.

which version of houdini are you using? 17.5 ? 18 maybe? have you tried in the other? due to the rapid API changes lately in 18 I have had other things break in 18 only. (fixed now in recent builds but was previously) so I would be great to compare just to be sure.

I'm using 17.5.460

I think that I've found the problem with the inverted attributes in the curves. I'll fix it for the next build.

Thanks for reporting it!

With regard to the denoising/post processing being irregular: turning the post processing off seems to make the denoising consistent.

*Edit: Scratch that, on further rendering, I notice the same behaviour again, random frames don't get denoised ..

I update from x1 to x3, and now cant even create Octane node from shelf. why?

Probably because you are working with an H18.0 daily build that has broken the compatibility with the plugin due to its changes in the HDK. You must work only with the Houdini production builds that have a proper Octane plugin build for them, which are 18.0.287 and 18.0.348 currently.

Thanks,
