[juanjgon]

Hi,

This is a production release of the OctaneRender™ 2020.2 for Houdini™ plugin compiled with the Octane 2020.2.3 core. This 2020.2.3.0 release is available for the latest Houdini 17.5/18.0/18.5 production builds on Windows x64, Linux gcc6.3.1 and MacOS 10.12 (CUDA).

Make sure to use an NVIDIA Studio driver with version at least 456.38 on Windows or 455.23 on Linux to use this version. No driver updates are required for macOS 10.13 (CUDA).

New features
To learn more about the new features and improvements of OctaneRender 2020.2, please check out the 2020.2 release post, but this is a brief list of the main new features that have been added.

• Improved RTX performance.
• Fast Spectral Nested Dielectrics.
• Denoiser support for the new NVIDIA Ampere devices.
• ACEScg and filmic processing. New color options available in the Octane ROP node.
• OpenColorIO Management, Display and Export (OCIO profile). Configured from the "OCIO" environment variable.
• OpenColorIOColor graph nodes. Look, Profile and View nodes
• Integrated multi-scatter from volumes or surfaces. Available in the Octane OBJ spare parameters.
• User generated compositor AOV passes for combining render and light passes in full a compositor node graph.
• Null material.
• Spotlight texture.
• New ray type, texture composite and channel tools shader nodes.
• Improved color correction node.
• New chaos texture node.

Release Notes
=============================================
RELEASE 2020.2.3.0
=============================================

* PLUGIN FEATURES AND FIXES:
- Added H18.5.532 plugin build.
- Added support for camera nodes inside subnets.
- Fixed missing shader system updates while working with transform nodes.
- Partial fix for a crash problem while rendering sequences in full scene reload mode.
- The IPR color space mode is now configured from the "Color space" Octane ROP parameter, to match the render to disk and to allow non clipped IPR preview in MPlay.
- New option in the Octane ROP node to configure the MPlay gamma.

* OCTANE FEATURES AND BUGS FIXED:
- Improved performance in some scenes with a scattering environment medium when using RTX.
- Fixed crash in the surface scatter node when you try to use the area based distribution on a mesh that doesn't have polygons.
- Fixed portal material being non-transparent to shadow rays.
- Fixed clamping of HDR input values in the color correction texture.
- Fixed CUDA failure when rendering toon materials.
- Fixed incorrect rendering of toon materials with opacity < 1.
- Fixed CUDA failure when vertices of a mesh are moved around in quick succession and RTX is enabled.
- Fixed broken auto bump of vertex displacement if dirt is used in the material as well.
- Fixed missing render update if a toon ramp is modified.
- Fixed superfluous geometry updates when an input of a volume node got changed.
- Fixed specular transmission "leaking" into the indirect reflection render pass.


Happy rendering,
Your OTOY Team

Thanks for fix environment rotation update in IPR. Works properly now

Unfortunately I don't seem to be able to get the imager response curves to work now?

Here it seems to work fine. Do you have the Color Space set to "sRGB" in the ROP node?

Thanks,
-Juanjo

[stevepickup]

ah yes that has done the trick - thanks.

Hey Juanjo,

Thanks very much for getting this release out. It makes a world of difference being able to adjust transforms in materials without having to reload to see the results!

A couple things I'm noticing immediately:

The Render Region feature in the IPR doesn't seem to be working. The red box shows up and you can drag an area as before, but the entire image area continues to render.

Also, I noticed that the IPR was taking a long time to calculate before beginning the render and found that even if you have the render flag set on an Out node on a node tree it seems to be going through and recalculating the entire tree before the rendering begins. If I freeze the Out node it starts right up with only a brief pause. I could be wrong, but I don't seem to remember this happening in previous versions.

I'll try to reproduce these issues again in a new file and will report back if I notice any difference.

Also forgot to mention I'm running H18.5.532.

Here the render region seems to work fine. I can't remember any change in the IPR features or in how the plugin extracts the scene in this latest version, so I'm not sure why you say that the extraction time is not the same. You should check if the same happens with the previous Houdini production build, perhaps something has changed on the Houdini side.

Thanks,
-Juanjo

Hey Juanjo,

Thanks for the quick reply. It seems that the node tree recalculating (particular the VDB conversions) may have been related to that file which was created in H18.5.499. As well the render region seems to be working properly after a restart. Thanks again for the feedback.

Does this work with Python 3 Houdini builds? On 18.5.532 the shelves show up but all the shelf items throw errors.

ie:

Traceback (most recent call last):
File "Add_Octane_ROP", line 1, in <module>
File "/opt/hfs18.5.532/houdini/python3.7libs/roptoolutils.py", line 10, in createRenderNode

Doesn't seem to be python 3, I installed the Python 2 version and still get the errors:
