OctaneRender® for 3ds max® v2020.1.5 - 10.17 Tweet

Hi Paride,
I dont remember what you told me before about the old and new volume behavior. Are they planning to fix new volume rendering very dark?

Can w e render particles with embergen. For some reason exporting vdb with particles from embergen octane wont render volumes at all ?

Thanks

Hi coilbook,
It's depends on changes on the step length of the medium node in v2020.
The solution is to have the Step length value higher.
Could you share the volume with particles you exported to .vdb?

Hi Paride,
HEre is the file attached.
Here is the link to the software if you want to export to vdb yourself. https://jangafx.com/software/embergen/
with screenshot of the software and the file

And can you also output a regular VDB from that program and input into octane volume. For some reason pivots of octane volume never align with original emitter mesh



Thanks

My GPUs are not going over 85% load. They are also getting low to 5%.
Temps seem okay. Using Studio Drivers 452.06 with latest Win-10 Pro. The Latest Octane built of course.

No "out of core" enabled and non of the two cards are set to priority.
While at current task "render passes renderings" it's at 97% constant.

It's quite a loss of computing power with two cards.
Are there reports that the drivers are causing problems or so?

Hi coilbook,
thanks, something doesn't figure out, maybe the unit of measurement.
Could you share the .max and .ember file please?

Hi mbetke,
I will send an .orbx in pm to test, I've 64GB on board then I cannot push up the render size.
Said that, I found some assets you could fix, like non Octane materials in xref too.

Thanks, but after loading your .orbx into SA the render just looks messed up too with given resolution.
Funfact: My scene get wired colors with 10.000x10.000px but renders fine with 11234x11234px. But lines are strange distorted. Like if I pull the upper half 30 degree to the left.

When I put a diffuse material on all assets it fails too.
I think Octane just fails on this scene.
Now I have to stitch some smaller renders of it into a panorama.

Is there any plugin, script that will render several parts of the scene for me? I will stitch it together in post then.

Hi mbetke,
the developers confirmed the Ai denoiser issue I sent, they will investigate further.
At the moment there a limit around 9k*9k.

Paride
