Standalone 2020.2.1 version for the network rendering nodes
viewtopic.php?f=24&t=77111


Release Notes
=============================================
RELEASE 2020.2.1.2
=============================================

* PLUGIN FEATURES AND FIXES:
- Fixed a bug in the gradient node.
- Fixed a bug in the Octane VOP node names after creating the first one.


=============================================
RELEASE 2020.2.1.1
=============================================

* PLUGIN FEATURES AND FIXES:
- Added H18.5.499 plugin build.
- Fixed a problem in the PDG ropfetch node while working with the Octane ROP.
- Addressed several issues related to the color settings while rendering to IPR, MPlay or file.
- Fixed the "Show Denoise" feature in the OpenGL IPR window.

* OCTANE 2020.2.1 FEATURES AND BUGS FIXED:
- Added option to automatically select the OCIO intermediate color space to the application preferences. This is enabled by default, but can be disabled to allow manually setting these.
- Brought back the dialog that allows retrying activation when the connection with OctaneLive has failed.
- Fixed bug causing moving instances to disappear when subframe start would be set to 100% in the animation settings.
- Fixed crash when an OSL shader has two outputs.
- Fixed crash when an OSL shader has a struct as input parameter.
- Fixed render failure when rendering a preview of a toon material.
- Fixed render failure when texture displacement is used on a mesh with no UV coordinates and RTX is enabled.
- Fixed AI denoiser on macOS by updating cuDNN to version 7.6.5.
- Fixed volumetric spot light cutting out geometry with a material priority less than 0. This is because the volumetric spot light had a default priority of 0, so if the user tries to set the scene geometry with less than 0 priority, they will be cut out.
- Fixed rendering of fake shadows of nested dielectrics that have SSS.
- Fixed missing attenuation if a toon material is indirectly visible, e.g. behind some tinted glass.
- Fixed material opacity not using the correct opacity when using mix material inside a layered material node.
- Fixed incorrect reset of material layers if a mix material gets changed and is used inside a layered material node.
- Fixed incorrect rendering of Vectron nodes with object layer / material map nodes if connected to an OSL texture with an _sdf input.


Happy rendering,
Your OTOY Team

Found a bug with the gradient tool.
On a pighead I have a material with procedural noise in albedo and a gradient in between.
Happens every scene I use a gradient.

Houdini 18.0.597(Windows)

I'm getting the same thing. It would be awesome if the path to the node could be displayed in the console to make it easier to fix. Am I assuming correctly that this is due to updates of specific nodes which break compatibility with files created using the previous version of the plugin?

Edit: This seems to have been an issue with the gradient node I had connected in my material network. I removed it and the IPR starts up without any console errors.

I'm also noticing a fair amount of CUDA 700 errors. I did a clean uninstall and reinstall of the Nvidia drivers as per this thread (viewtopic.php?f=86&t=70433&start=10)and checked to make sure that my TdrDelay is set to 10 in RegEdit, but it didn't solve the issue. If I move around the frames of the animation while the IPR is active this error shows up every time. A restart of Houdini is required to reset it.

*** OCTANE API MSG: -> failed to deallocate device memory
*** OCTANE API MSG: CUDA error 700 on device 1: an illegal memory access was encountered

On the plus side, I'm noticing that Octane isn't bringing Houdini down with it when it hits a major error like this which would be a major improvement if that issue has been resolved.

Sorry, I've found the problem with the gradient node. It was related to a change in the Octane core gradient node pin names done without notice. I'll release a new build shortly including this fix.

Thanks,

Sorry, do you have this problem with any scene? It could be great to have a scene to try to reproduce the problem here. If you can send us an example scene with this problem I could take a look at it.

Same issue for me, Im' just back with octane and already disappointed :/

"On the plus side, I'm noticing that Octane isn't bringing Houdini down " yep I've noticed that too

Great! Maybe a solution to avoid something similar in the future could be a simple "material scene" with multiple spheres containing every material, texture and tool supported by Octane. Just a thought.

I've updated this post replacing the previous build with the new 2020.2.1.2 plugin build, which includes the fix for the gradient and ramp nodes problems.

Thanks,
