OctaneRender™ 4 RC 7

[Notiusweb]

Hi Marcus,
I sent another test scene to you, it involves polygons becoming visible when I overlapped an FBX with an ABC file.

THX!

I got another crash while rendering frames, seems to happen around frame 260-280 last couple of times. Win 10 just reports shut down due to possible power issue, and then reboots.
Didn't have Nvidia's "Prefer Maximum Performance" on, so will try that.

Is there an error or crash log in the standalone version, I know some of the plugins have them, but don't remember where it is if Standalone has one.
For this, not really sure it is Octane, but wondering what log might say.
Thx!

UPDATE
Tried Nvidia's maximum performance setting, and no crashes with longer renders.
Only thing is that I latest tried the render also during day where I was using PC as well for other smaller tasks while rendering...Perhaps other use kept PC awake, or alive, or whatever.
But in any event, not seeming to be an Octane specific issue.

@Notiusweb-where do u set this max performance settings?

Thx

Hi,
In Nvidia Control Panel:
"Select a Task" window bar on Left
3D Settings (dropdown)
"Manage 3D Settings"

In Global Settings Tab Window, under "Settings:"
Feature - "Power management mode"
Setting - Prefer Maximum Performance

(Click Apply)

When I use this, temps will run higher on cards because cards won't return to idle as much, and when they hit their top, they will stay there longer because they are not pulled back down immediately from max power usage.
But trade off is that PC is not throttling power to cards up and down, so there are less system flags and alerts involving power usage by the GPU that may trigger a protective shutdown by the PC.
Apparently from reading online, PC throttling power to cards may otherwise be a reason if PC reboots during rendering processes, or gaming.

Hi Maybe I am missing something but when are we going to see an option of a real time rendering like you showed us with Brigade? Thank you

[coilbook]

Well RC7 is giving the same error of exceeding 20 devices even though I am using exactly 20

"OctaneRender 4.00 RC7 (4000017)

the total count of GPUs used locally and over the network exceeds 20. ignoring slave ..... with 5 device(s).

I love this question so much, and as I have worked with raytracing and realtime PBR engines, I feel like I have seen enough now where I can answer it!
Until the hardware advances, you are not going to see realtime raytracing...unless, that is, the scene is an easy scene for Octane to render....
(1) Even if you stack RTX 2080Ti or Titan V GPUs into infinite, the CPU will bottleneck them to some degree (even if only a second or 2), as far as the scene info being fed to them.
(2) You aren't missing anything,. But, it was the demo scenes that were missing things - ie, full 1080p resolution, and higher rez meshes and materials, like you are likely using.

I use the Sketchup plugin, for example, and I can render pretty much in realtime, at low or mid-res, because the scenes wind up not being complex at all. Looks like all the Brigade demos.
But make it a Daz scene, or a 3DS Max scene, with all the higher fidelity meshes and materials...forget it. No way. See, they were never giving you high-res complex scenes in the demos.
Now, keep in mind, though, that V4 is faster than anything else out there, on an exact matching scene to scene comparison, renderer to renderer.

And, look at this Brigade video from a couple years ago...does it really look much different than what you can do now? Remember, imagine the scene was likely lower res and had limited amounts of materials.

But, I can sympathize. I imagined UHD resolution, with 4K textures on high count mesh scenes, rendering in real-time….not yet
Kind of like some cell phone company's 'unlimited' data plan...unlimited up to a certain point, then it slows down....although, it never shuts off....

[coilbook]

Thanks a lot for the answer! You are right. My scene also has lots of trees with leaves ,grass, etc. It might be years before we get even close to real time.

Also if it takes 1 min to render (1000 samples per frame) 30 seconds is used by processing geometry and denoising. Hopefully these numbers will improve in the future. The scene only has 15 mil polys.

I agree, people seem to look at the Brigade demo through some pretty 'rose tinted glasses'
Not only are the scenes generally pretty low poly, the scenes that do have higher poly counts also have pretty simple surfaces. And it's all very noisy.
I would imagine that if Otoy created a new "Brigade demo" once the RTX features are enabled in Octane 2018 (probably 2019 looking at how much of the year is left) using DL and AI denoising, it would look a lot better than the Brigade 3.0 demo did.

btw, is it ok to ask if Octane 4.0 is actually going to see a release this year, let alone Octane 2018???

Cheers, Dan.
