OctaneRender 2021.1 for Houdini production build 2021.1.2.1

[juanjgon]

Hi,

This is a production release of the OctaneRender™ 2021.1 for Houdini™ plugin compiled with the Octane 2021.1.2 core. This 2021.1.2.1 release is available for the latest Houdini production builds on Windows x64 and Linux gcc6.3.1.

Houdini production builds supported by this release: 17.5.460, 18.0.597, 18.5.759, 19.0.455, 19.0.498 and 19.0.531

This build includes the first beta version of the new Qt5 IPR Window, the core of the plugin's whole new IPR system that will replace the old OpenGL IPR Window. There are still some important features missing (like render region, camera selector, shortcuts/preferences, background image, or snapshots gallery) that will be added this year, alongside the viewport IPR rendering feature, but the core technology is ready to be tested. The new Qt5 IPR window is available for both Windows and Linux (and macOS in the future) and it can be opened as a floating window or inside a Houdini pane.

This version supports Nvidia Ampere GPUs and as a consequence, we had to drop support for old Kepler cards with a compute model < 3.5. And please make sure to use a NVIDIA Studio driver with version at least 456.38 on Windows or 455.23 on Linux

Release Notes
=============================================
RELEASE 2021.1.2.1
=============================================

* PLUGIN FEATURES AND FIXES:
- Fixed a problem with the Cryptomatte layer names.
- Fixed a problem related to missing AOVs when Cryptomatte is enabled.


=============================================
RELEASE 2021.1.2.0
=============================================

* PLUGIN FEATURES AND FIXES:
- Added H19.0.531 plugin build.

* OCTANE 2021.1.2 FEATURES AND FIXES:
- Reverted the conversion from color/RGB texture to grayscale back to what we were using in 2020.2 and before: Picking the red channel.
- Improved update speed of AI light in heavy scenes with lots of emitting geometry.
- You can now set log flags using the -D parameter when starting a net render node directly via the command line.
- Fixed render failure when nested dielectrics are enabled and the scene contains lots of overlapping geometry.
- Fixed crash when saving HDR render passes if cryptomatte is enabled with info kernel.
- Fixed Octane hanging under rare circumstances when Cryptomatte AOVs are exported.
- Fixed crash when a user instance ID Cryptomatte AOV is being saved.
- Fixed crash of net render nodes if the scene uses PMC + info AOVs.
- Fixed artefacts in interactive render region when Cryptomatte is used with network rendering.
- Fixed handling of negative values in IOR maps, to make sure it behaves the same as in 2020.2.
- Fixed glossy material inside glass looking wrong with nested dielectrics
- Fixed incorrect/not working vertex displacement on Ampere GPUs.
- Fixed rounded edges to not to render correctly on Turing GPUs with scenes that have both static and moving instances.
- Fixed net rendering with "AI light update" enabled causing visible discontinuities at the boundary of tiles.
- Fixed incorrect value in P if an SDF is evaluated directly and as an input for a "Volume to texture" node.
- Fixed incorrect subsampling of shadow passes.
- Fixed tangent normal AOV to always apply bump/normal mapping.
- Fixed alpha operation "Blend mode" of composite output AOV node, which was causing blending operation to produce incorrect result. This fixes discrepancies between the main AOV and a combination of the light AOVs.
- Fixed "Opacity" setting of "Composite AOV output layer" which wasn't applied correctly.
- Fixed missing updates when the scene changes while a Cryptomatte AOV is being tonemapped.
- Removed spaces from exported Cryptomatte EXR layers as Nuke couldn't deal with them.



Happy rendering,
Your OTOY Team

Hey, thanks for the release.
I have a bug after update - no AOVs (LightIDs for example) in the rendered EXR, only cryptomatte. Had to roll back to 2021.1.1 and the same scene renders well.
Using network rendering, acesCG (not via OCIO this time)

Thanks

Hmm, let me check it out. I wonder if the problem could be related to a change in the Octane SDK related to the EXR layer names. Are the AOVs really missing or are they there but with no name?

Thanks,

I don't know if this is already planned but it would be really nice if there would be some color settings in the new IPR too, like redshift has.
Where you could see and change the colorspace, edit the post processing settings and also preview exposure and contrast adjustments!

these two are from 2021.1.2

these two are from the same render, but 2021.1.1.2

seems like they are not there at all

how Octane love to change the names in a minor releases..

Ok. I've updated this topic including a quick fix for this issue. The new build is 2021.1.2.1

Thanks for reporting this issue!
