bifrost foam - how to render with vray 3.1 ?

[IngoSchoeller]

Hi,
just trying out maya2016 bifrost with vray 3.1.
How can I render bifrost foam with vray ?

When I have a bifrost simulation and I add a foam node to this simulation, vray only renders the bifrost liquid but not the bifrost foam.
Mental ray renders both (liquid and foam) but vray only renders the liquid.

What do I have to do so vray renders bifrost foam ?

Thanks a lot
Ingo

Hello,

Unfortunately this is not supported yet. I'll update the thread when we have more info on that.

Best regards,

[IngoSchoeller]

Okay, thanks.

So I will wait.

is there any progress on this? is there no way to render bifrost foam in any capacity inside vray? any workarounds? Maybe using Phoenix shaders?

Foam is now supported in the 3.35 nightlies. Technically, it may be possible to write a Python script for 3.1/3.3 and use VRayMtl, but it's best to get 3.35 if possible.

it works in 3.35 but it crashes as soon as you add motion blur

[ivaylo.ivanov]

Ok, will see that, it's still being tested.

The motion blur should work in the next nightly.

[miguelortega]

does that mean its up now? i didnt see it in the release notes.

Hi Ingo,
How did you get the foam to work with the new nightly 3.35.
Is there some specific workflow it. I tried enabling export particles/voxels on vray extra attributes to foam and liquid shape. But I am unable to get the foam working.

Thanks

I just rendered it right from the bifrost foam object. Using the bifrost foam material. The liquid was the remesh. Motion blur crashes it instantly though.

Thanks for the reply Ingo,
I got it working too, it made a mistake with scale of the scene and couldnt see anything earlier.
But yes, I noticed that maya crashes when motion blur is enabled

[miguelortega]

No prob. Not Ingo btw.

I am so sorry, I somehow had the name fixed in my mind.
