OctaneRender™ 2020.2 XB4

Wed Oct 21, 2020 7:54 pm

Dear all,

We are happy to share our fourth experimental build of Octane 2020.2. As with all experimental software please do not use this for production purposes.

This release includes now all major features that will be part of the final 2020.2 release in addition to a number of bug fixes including some of those that have been reported by you in previous 2020.2 XB builds. There are still some outstanding issues that could not make it to this release but we are making good progress and they should be coming in the next one. 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OctaneRender 2020.2 XB5 has superseded this build.

Changes since OctaneRender 2020.2 XB3:

New features:

Added new surface and volume scattering tools which are exposed via the new geometry nodes Scatter on surface and Scatter on volume. This allows procedural generation of arbitrary number of instances according to various patterns that can be configured to achieve many different results on both geometry surfaces and volumes.
Added new primitive types Torus, Elliptic torus, Ellipsoid, Figure eight, Saddle, Hyperboloid and Ding dong, to the Geometric Primitive node.
Added new AOV compositing tools exposed via a new Composite AOV group input pin in the Render Target node. This allows you to assemble, blend, change contribution of render passes to produce a new output without having to start a new render. This is fully customizable and allows any arbitrary number of inputs. Some common usages would be changing the color and intensity of lights (light mixing), organizing render passes, changing volume color, applying fast fog as a post and more.
Added denoiser support for NVIDIA Ampere devices on Windows and Linux builds.

Bugfixes:

Fixed CUDA error happening when using nested dielectics with multiple instances.
Fixed application crash happening when processing HTTP requests which use redirection.
Fixed application crash when deleting a geometric primitive node while being rendered without a render target node.
Fixed application directory path on Linux not using the same hidden folder as previous stable builds.
Fixed potential application crash when showing an OCIO combo box via a Lua script.
Fixed potential application crash when clicking on Find by pattern... when loading images for an image tiles node.
Fixed unnecessary prompts of the sign in dialog in some scenarios.

Looks like this update contains Lightmix and multi-scatter!

Is there something the Slave node needs as it's failing to run?

Thanks team! Looks nice! A short tutorial on how to use the composite would be appreciated.
Scattering objects is very nice!
Looking forward to see the Chaos texturing node!

PS: Composite AOV is awesome, have just figured how it works!

Cool! Does it work as expected? Really looking forward to this one

As long as I tested: YES! It Is very flexible, it lets you create many "scenarios", combinations with altering the main scene lighting. There seems to be all photoshop standard blending modes.
So far so good. Soon we will see how far we can stretch this feature.

I love the sound of all the new features, but I really wish you guys would post some examples of how to use the new scatter tools etc

But I have to say, I think it's ridiculous too announce new features and not have any examples to refer to - I've been with you guys for nearly 8 years now, but this kind of thing is what will make me jump ship.

Lino Grandi posted images of the new scatter functions on the Octane Facebook group, can you guys not quickly russell up some examples like these please ?

Thanks so much for this, really appreciated - for Volume Scatter, is it possible to clone onto imported geometry or is it confined to sphere/box/cone etc ?
