OctaneRender® for 3ds max® v4.00-RC2 - 6.05 [OBSOLETE] Tweet

[coilbook]

when using itoo forest (lots of trees) and opening octane viewport, octane renders but viewport is just stuck at evaluating scene

Hi Paride.
Did the test for three shots from one angle. The first frame of 7:17, second and third in 3:40. Thanks.

Hi justix,
you can use wetransfer, then send me a download link.
I would test a .max file with your Octane setting.

Fine, the test scene is damn simple and this time I set the denoise NOT to denoise on Completion and oddly enought if I take ONE object out ( around 10 MIl faces ) it render and Denoise without much effort apart from the time it takes to denoise BUT I wrote down few bits out of the memory usage and here my tests, I hope my cards are working right because if I can't render at least 5GB Vram scene what is the point of buying an 8 ( and f..ck Nvidia for not Linking the Vram having 2 X 1070)

The working configuration up to 10 Mil faces and WITHOUT Denoise on Completion works as follows:

Render Complete 3.089 / 3.386 ( these are never the same ) AND when switched to Denoise Pass it goes to 3.160 / 4.361 (?) secnd try goes 3.514. Like if something in the background is eating Vram up or releasing it...

SO it looks like to denoise it takes about 100MB ?

THEN

Same With Denoise on Completion 3.089/4.012 and down to 2.730 / 27.30 while swithing to denoise pass ( taking it quite few seconds..)

Anyway even using a more regular Mesh file ( stl ) it goes bananas pass the 10 Millions faces on my rig..the rest it just very random in it's usage. .. I will PM 2 files

Hi justix,
I tested your files, I opened them and pressed Open OctaneRender viewport, only I set up parallel sample 16.
I made this test using a single gtx1070, 16gb, windows 10, Nvidia drivers 399.07 (I'm testing last drivers). As you can see windows 10 eats little less 20% VRam.
Does my test meet your expectations? What about your opinion?

Hi
There is still an unsolved bug with multiple phoenix grids and octane scene evaluation times:
Adding more than one grid increases eval time by a lot!

I have this scene with one phoenix grid eval time is 1 min 20 sec. With 4 grids it is 4 min 30 seconds. (and this is in octane 4 with fast geometry processing)

That is crazy. Each grid contains sim files around 2-3 mb only. Why is adding more grids with small sim files increases eval time so much?

This is definitely a bug otoy has not solved yet similar to slow processing times when there are a lot of objects in the scene

Can't say much until I test those drivers too, otherwise I should start worrying about something bottlenecking my Vram or worse?

EDIT: This is the very best I can go ( with this scene but we are talking VRAM used and Number of Primitives ) and it just like yours.but no matter what...if I change Cards Denoise Configuration and Tone..can't go more than 8 Parallel and as soon as I add one OR a Mesh it goes out of memory for Denoise..but generically speaking I can't pass the 10 mil that It hault my PC.., Also it seemed that opening Photoshop for editing the screenshot affected the VRAm in a way because it kept give me GPU Fail even witha 8 mil poligons and I had to reset the PC to re-render the scene as you seen in the screenshot.. dunno what to say, maybe your 16MB 1070 has more room thna my 8GB... would be good to know the very best AND tried to export the scene on the standalone adding up about 3 extra mesh reaching 11.5 million and as you see the standalone did not crash or gave me any error although it took a little while to denoise you can see the used memory and the avail with more geometry inserted..

8 parallels

16 Parallel 13 mil primitives and not crashing on Denoising or stuttering viewport

Hi Border mode is not working

Hi Justix,
As I can see, you have very little VRAM available to render (3dsMax screenshot 2,789 GB), that's your issue..
Keep in mind, use VRAM:
OS, monitor/s and softwares (3dsMax, Chrome, photoshop etc..)
parallel samples set to 1, then Octane uses 51.3MB for an empty scene. If I set it to the new max of 32, then it'll use roughly 32 times that ie around 1400MB. Increasing parallel samples helps render speed. If you don't have a lot, then you should use 8 or 16.
try to do this test and screenshot by following these directions:

1 geforce GTX 1070 active(no) Priority(no) Tone(yes) Denoise(yes) > connect here your monitor/s (
2 geforce GTX 1070 active(yes) Priority(yes) Tone(no) Denoise(no)

in this way you should have 8GB VRAM avaible to render and 8GB VRAM avaible with OS, softwares, monitor/s, tonemap and denoising.
This should solve your issue. My advice is to get a GPU with at least 3GB on board to manage OS, soft etc ..

Well I don't pretend to render a scene where the Vram has reached the 8GB Vram avail BUT I understand that is more like a 3dsmax issue because the Standalone can render with higher number..as long as I know it I'm fine BUT correct me if I'm wrongthe Istance is still causing trouble because an object istanced should NOT count in the Primites number?looks like in this version it is not..

An I can't add one more GPU because my ASUS X99 IIA only got 2 PCI-E Available .eventually if I have a large scene I will try to deactivate one card.. will screenshot and report

Hi justix,
As I can see in your screenshot, you have only 3.4 GB VRAM avaible using SA, instead using 3dsMax 2.7 GB VRAM avaible, SA has not 3dsMax viewport.
your computer eats all the remaining VRAM.
