OctaneRender™ 2020.2 RC3

Dear all,

We are happy to share our third release candidate build of Octane 2020.2. Note this is is still not a production build so please do not use this for production purposes.

This release includes now all features which will be part of the final 2020.2 stable release. This includes fixes from issues you reported in previous builds as well as some functional updates according to your feedback. Note we are keeping track of all your reports but there are still some fixes could not make it to this release, we are making good progress and they should be coming before this goes into production. Thank you all for your support.

Should you find any issues with this release please report using this thread so we can make sure we provide you with the best feedback.

Make sure to use a 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).

This version supports the new NVIDIA Ampere architecture on Windows and Linux. Kepler cards with compute model lower than 3.5 are just supported on macOS.

OctaneRender 2020.2 RC4 has superseded this build.

Changes since OctaneRender 2020.2 RC2:

New features:

  • Added additional blending modes to the Composite texture node.
  • Added a mask input to the Composite texture node which is used as an additional input to some of the blending operations.
  • Added alpha operations to the Composite texture node.
  • Added new Color AOV node which represents a color input to be used as an AOV.
  • Added enable flag to each layer within a Composite AOV which when enabled such layer is used during compositing.
  • Added opacity input to each layer within a Composite AOV which specifies the opacity channel used to control the transparency of this layer.
  • Added alpha operation input to each layer within a Composite AOV which specifies the layer's alpha operation.

Bugfixes:

  • Fixed CUDA error when using AI light.
  • Fixed vignetting which was not working on composite aov.
  • Fixed issue updating composite AOV settings when coneccted via a linker node.
  • Fixed chaos texture producing LDR output for HDR input images.
  • Fixed issue which would cause to display ? instead of the number of CUDA cores in the device settings for Ampere devices.
  • Fixed displaying unnecessary OptiX error message for devices with compute models lower than 5.0.
  • Fixed white artifacts showing up when rendering with compute model 3.5.

Other changes:

  • The Chaos texture does not perform histogram calculations by default when the upstream texture is updated. This would generate results closer to the input for LDR images at the cost of background processing. The old behaviour still be enabled using Histogram invariant blending.
  • Updated the way some blending modes are referred to in the Composite texture node.
  • Updated Composite AOV node icon.
  • Moved common pins from Render AOV input, Image AOV input and Composite AOV into each of the layers of Composite AOV node.

Hi,

So I have looked into this and found that this is caused by some backwards compatibility with how the Octane BRDF has to work while there is only diffuse and specular reflection, and this is not really fixable as it would affect the things we are trying to be backwards compatible with work (this would impact the consistency between glossy material with Octane BRDF and universal material with diffuse and specular reflection with Octane BRDF).

Would it work for you if you use other BRDF models instead? This restriction is only posed upon the default Octane BRDF.

BUG: Expanding nodes on composite aov does not connect expanded node

1. Add a composite > composite AOV
2. In the node inspector, right click on any pin icon > expand

RESULT: The node is expanded, but not connected to the pin.

I'm guessing this is somewhat related to the previous bug I submitted with the composite texture.

Yes - I ran into this too.

Thanks for the report this will be fixed in the next build.

Im running into errors like this using the composite texture. I havent figured out exact steps though.

Once it fails, you need to restart standalone to get it working again.

BUG: Composite texture generated invalid OSL code

It seems like the previous post is very simple to reproduce.

1. Load the attached OCS
2. Open a windows > create log window and dock it.
3. Right click the diffuse material > render

The following log error occurs:

Code: Select all
