Connecting a Toon Material to a Layered Material's "Base Material" pin gives this error:

It also seems to hang Octane for a while if you try to stop the viewport. Restarting gives this error:

Code: Select all

device 0: failed to bind device to thread, since it's already bound
device 0: failed to initialize context

After closing standalone, the process doesnt die and cant be killed in task manager either. GPU-Z shows 100% GPU load

Can someone explain how the composite material "material 1 mask" can be used?

It doesn't seem to do anything no matter what greyscale color value I use, since there is no layer "under" it

Right, it doesn't seem to have any purpose or effect, or even being evaluated.
I guess we can just ignore it for the moment.

Found bug where sometimes Batch Render won't catch the application of AI Upsampling on the saved image. It will show it rendering, but then the frames are without the AI Upsampling, jagged.
Then other times it catches it fine, not aware of any pattern why this is.
I do know where in cases when it happened I had stopped the batch and then started up again.
When it worked, it was the 'first run' of the batch since opening the application.
So a workaround is to turn off Octane, open application up again, load the scene fresh and then run Batch.

Maybe something to do with the timing of the saved image, because either they all get saved with AI, or none do.

Actually I am finding that with Up-Sampling enabled, I can't use any passes, Octane becomes unstable and either sends GPUs to orange, where I have to restart the scene, but then it goes orange again as soon as I try to render with passes, or just outright crashes like it does when saving an EXR or PNG 16-bit.
So essentially, passes don't work with up-sampling.

I made a Ginormous discovery -
When I just use only my main Titan Xp on the Mobo, I get NO issues with any of things I have been yapping about related to crashing-
1) Saving EXR, 16 bit PNG
2) GPUs going orange-warning when changing AI-sampling modes
3) not being able to use Render passes with up-sampling

BUT - as soon as I enter in either my 1 Titan X Pascal, which is also on Mobo, or my 6 external Titan X Pascals connected on PCI 1x USB 3.0 risers, I get the issues...

In fact, with just 1 Titan X Pascal, either on Mobo or external, things fail. For example, with render passes when using up-sampling GPU gets the red warning that it failed.

Almost as if XB2 can't work right with Titan X Pascal.
Now, XB1 had no Titan X Pascal issues, so this is very interesting, weird, and most importantly...

Not exactly the same, but I have found in general that all of the render pass masks do not match the item being masked. If you actually use them for compositing there is always an outline.
Now, if you use a straight PNG with alpha over a background, it works great...BUT, this is good for single images.
But for an animation, where you would want to compose a mask video layer and perhaps have >2 layers with masked items in front back of a main layer, the render pass masks are useless because they don't match what is rendered in Main pass. Octane does not have good render pass masking for some reason. (This would be Render Layer Mask, Object Color, Object ID, Render Layer ID, etc)

Thanks, this is helpful. I am using a Titan X Pascal exclusively for rendering so it is likely something else. We will figure it out.

CUDA crash toggling shadow catcher pin on and off

1. Load the orbx and select the render target to start rendering
2. Select the mat1 nodegraph > diffuse material
3. Toggle shadow catcher on/off a few times

CUDA error 719 on device 0: unspecified launch failure

Thanks for this feedback.

I am going to test the scene using the latest code,
because there have been a lot of code changed happened after xb2

Hey notiusweb,

thank you very much for your feedback

Because I have done a overhaul on the upsampler code and it totally changed the way how it will process the films,
Can you please share a demo scene with a pass stack, so that i can check it using the latest code?

Thanks
