OctaneRender™ Standalone 3.04.4 Tweet

[abstrax]

Hi all,

This is just a minor update we are pushing out to fix a regression in the direct light calculation of transmissive materials. It also improves the render job graphs.


Changes since version 3.04.3:

• Added an output directory to the render job graphs.
• Added a render job group node.
• Added a group attribute (A_GROUP) to linker nodes which is used by the node inspector to group inputs, when given. We use it to arrange the inputs of the batch render job graph. We will add the ability to manually specify groups via the GUI in the next release.
• When a new project is loaded the current project is first replaced by an empty one, before the new project is loaded. This should trigger a reload of all assets. (see viewtopic.php?p=294382#p294382)
• Fixed incorrect direct light calculation of transmissive materials (see this example: viewtopic.php?f=103&t=57359)

License tracking change since version 3.02

To implement the floating licensing system we need to keep track of all Octane processes that use a specific license on the computer. This way we only release/deactivate a license when no Octane process is using that license anymore. Originally we used a third-party library for that. Unfortunately there were various issues with that and caused crashes during startup in various circumstances. To fix the problem we changed it to an internal (file based) system in version 3.02. Unfortunately this separates the license usage tracking of version 3.02 and higher from the usage tracking of 3.00, 3.01 and 3.01.1.

-> Please make sure that you only run either version 3.00, 3.01 and 3.01.1 at the same time or only version 3.02 or higher.

Thank you for the new Version! Sadly it doesn't solve my problem. I attached two images rendered with the new version. HDR without importance sampling:

Glass__0000_Without.jpg

and with importance sampling:

Glass__0001_With.jpg

I also testet with an older Version 3.03.3 --> same result

kind regards

Thank you for the new Version! Sadly it doesn't solve my problem.

That looks more like a difference in noise. Enabling sample environment will give much less noise if your environment contains light sources. Do you have fake shadows enabled in the glass or foam materials? If so, subsurface scattering will often be rendered brighter, but with much less noise.

Mhmm, ok. but if i use Emitter instead of HDR the result is even worse:

As a workaround i bake the lighting with a panoramic camera. But it would be great if normal lights work aswell.

Edit: Oh and yes Fake Shadows are switched on on every transparent material

What are the kernel settings in this scene? What are the maximal path depth settings?

[Hesekiel2517]

I set the Depth really high but it has no effect on the foam:

It's the newest Modo Plugin, but it is also the same in Octane Standalone.

Edit: Ok I tested a little further. The problem only appears with a diffuse material and SSS. From left to right: Specular with SSS, Diffuse with SSS, Diffuse without SSS

Hi,

Did you try to deactivated fake shadow on the "Glass" Specular shader? Is working nice then for me? Also why deactivated environment "importance sampling" is better to have on will be cleaner faster.
Please look the image is that you are calling "bug"

Best,
JO

Hi,
In my octane standalone 3.04. the portals option doesn't work.

Portals window is blocking the sun rays.
Please see attached images.

PORTALS ON

PORTALS OFF

Can you help me and explain what could be wrong? In the past it was working with the same file.

Thank you in advance,
Jan

Hi Abstrax,
Do you remember that thing with the PC freezing because of devices being connected to splitters (Amfeltec) , and I measured that DPC latency was very spiking high right before a crash, and then I found the high spike was associated with the Post Processing being switched on, and then you did that thing with the tonemapping so we could deselect the devices that were causing the crash?

Just to follow up on that thing, was using C4D to export frames through Octane plugin, and in that process, it seems to operate very interestingly. Unlike the standalone which applies post processing at the beginning, the C4D process renders the image without post processing, and then right at the end it slaps the Bloom effect on it. When this happens, and I see the image update with Post Processing, there is a predictable corresponding high spike in DPC latency. I do not get crashes as I use my main board-connected GPU for tonemapping alone, so the DPC latency is not high enough to crash my PC. But it really shows that the post processing was the killer.

Just in case Octane ever starts acting stupid like a wiseguy, it could very well be that son-of-a b!^@# Post Processing drawing too many pc (or GPU?) resources.

I can confirm this, I'm having the same issue with a current scene of mine.
Up till vers. 3.04 Portals worked fine, after it, something is broken with them.
Also, 3.04.x versions are rendering much slower, with portals enabled.
