Hi, Is there any way to grab the density of a volume in a volume gradient to map the direction of scattering phase ?
I'd like to have high phase direction in low density part and 0 in hight density part ?

Any trick ?

Hi, I'm trying to render a vdb created from the camera frustrum. Octane render it but it is not in the right place.
you can see the attached image file, I can't upload the hiplc file. vdb from cam debug.jpg

If I resample the vdb, everything goes fine, but I don't want to, I just want to keep the ...

That exactly what I did. And it work indeed, but I don't know why, sometimes It does'nt want to set my key. I'll try to investigate and notice you if I can reproduce it.
Thank anyway.

Hi, I can't set any keyframe in the daylight system. How can I animate it ? any tricks ?
thanks

No need for debug scene. I was indeed merging volumes without grouping them before.
Thank for the tip.
After creating a primitive group for each volume, octane can render the merge properly.

Hi, When I try to merge 2 vdb's, octane only render the first one.
It work in mantra or Redshift but not octane. Is it a bug ?
I cannot combine them using a vdb combine cause i need them to have differents resolution.
Any help ?

good to read that.
Do you think we also will have attributes mapping available in this build ?
cheers

Hi, I cant find any transmition parameters in the new universal shader.
There is somme in the standalone version. Did I miss something ?

Hello,
I tried to connect some procedural noise to the scattering input of a volumetric medium and it seem to does'nt work.
I can connect it, but no matter what i change, I don't see the texture.
How can I achieve it ?

I don't want to use any vdb file as a volume, I just want a textured volume as ...

Hi,
Is there any way to combine 2 volumetric shaders to use both reflective and transmitive phase ?
Or simply have a shader with 2 phases and a blend factor.
I do this trick in our render engine at work to have better volumetric cloud rendering, and it's really imortant for rendering high ...
