OctaneRender™ Standalone 3.00 alpha 1

[Silverwing]

Volumes cause light to enter inside closed spaces.
I attached an image illustrating what happens inside a closed box when a volume intercepts the surface.

Hi there. I just wanted to let you know that I am running into the same problem.
I know its being looked after. Just wanted to confirm that there is a problem with shadows!

nice rendering. How much slowdown do you get when you add smoke?

I just tested it:
Without steam it rendered 2:40 Min
With steam it rendered 5:10 Min
Ray Step Lengh at 0.1

Pathtracing:
Diffuse Depth 5
Specular Depth 8
Coherent Ratio 0.3
Parallel Samples 16
Max Tile Samples 16

Rendertime 2:40 min

This is strictly notes related to Speed and multi-GPU:

Standalone 3.0 alpha 1 with 12 GPU


(1) Display choppiness - I am finding with 12 GPU that the view-port display has choppiness when attempting to pan zoom or rotate, and this choppiness is there even with subsampling 4x4. In experimenting, I find that as I reduce the # of GPUs towards 1, the display linearly smooths up such that when you then pan, zoom, rotate, etc., with 1 GPU it is very smooth But, as I increase active GPUs and get closer to 12, it gets linearly increasingly choppy as I pan, zoom, and rotate. I note that the choppiness/stutter/low frame rate-ish effect occurs despite the fact that I have a dedicated card for display not used in the rendering (Titan X).
Most relevant, the linear increase in display choppiness does not occur in 2X build, in any range between 1 and 12 active GPUs, it is always smooth.

(2) Rendering slower (unless you max parallel and max tile samples), expected per developer notes

6 sec on 2.32.2

18 sec on 3.0 Alpha 1 - default

8 sec on 3.0 Alpha 1 - Max parallel samples and tile samples

Thanks for reporting this, it appears to be a slightly different problem. Would love to see the final render once this is fixed

hi admin! how to save deep animationsecqunce .exr files? Seems like the batch rendering can only save regular exr but not a deep exr??

Hi admin, I still got no answer~ would u please explain how to save animation secquence deep exr files??or should I save the deep exr file frame by frame?? Thanks!

You got your answer two days ago: viewtopic.php?p=259390#p259390

Of course, it doesn't help if you spread the same question over halve a dozen places...

where my profile yet? How can I activate render without access to your password?
this does not work

abstrax, can you have a look at this scene?
Why do the renders look different? Why is the gpu usage not at 100%?

It will ask you to reset your password. I think the old password is the same password you had in the customer area before.

Is it possible to try Blender-SmokeSims in Octane3_Alpha ?

No, the Blender developer are on it to get openVDB included in Blender but it need month to get it working maybe Blender 2.8.

Hi all,

I'm just now trying out the new 3.0 alpha and it seems my 3 GTX 780 Ti's fail every single time I try a project, no matter how complex or simple. I've even tried creating just a simple box, sphere, cylinder geometry test with 3DS Max. I export to OBJ format and within a minute or so, one of my cards will fail in 3.00 alpha 1 and then shortly after the rest of my cards fail. The viewport just locks up and will not move. I have no problems with the same project file(s) in 2.24.1 (standalone or 3DS Max plugin).

Any ideas?
