In the past few days, I was working on my new project to achieve a new look in organic render, and the results are very satisfying. is it possible to achieve this type of render with the LuxCore too?
The technique that I used is rendering volumetric shaders on top of the mesh object by adding displacement, noise, camera projection, etc.
The renderer that been used is Arnold and I manage to achieve the same result in 3dsmax and Maya.
Here is the result.

Re: Volumetric render ....
It looks more like a VDB object/file to me (note: we support OpenVDB), as end result of some kind of simulation. As for the material, a NULL material with a homogeneous volume with scattering should do the job.
Re: Volumetric render ....
For the VDB object that's going to work but what about the mesh object, at volume applied to it.
It is a mesh object that used as a volume with a complex shader on top of it, it possible to add the shader to VDB too.
Here is another example that I'm working on.

Re: Volumetric render ....
The shader looks like a procedurally generated volume (but the labels are not well readable). You can try to bake the procedural volume in a VDB and than use the VDB with LuxCore (if baking is avilable). Otherwise you need exactly the same procedural nodes in LuxCore (and I doubt there is a 1:1 match even if I can not read the labels).TAO wrote: ↑Fri Jul 02, 2021 2:22 pm For the VDB object that's going to work but what about the mesh object, at volume applied to it.

Re: Volumetric render ....
Thank you for the explanation, I will try to bake the scene in VDB format, just one question, can I apply displacement on the LuxCore volume shader?Dade wrote: ↑Fri Jul 02, 2021 3:36 pmThe shader looks like a procedurally generated volume (but the labels are not well readable).

Re: Volumetric render ....
No ... but yes: displacement is applied only to surfaces but volumes are defined as the space inside a surface so the end result is the same.
This is the volume of a sphere with applied displacement:
The original surface with displacement:
Re: Volumetric render ....
TAO, can you maybe post a link to the Arnold documentation where this feature is described?
Re: Volumetric render ....
This video is the best one available that you can see the behaviour.
I made a video tutorial of how you can do such things and I will update that too because the tutorials and documentation are just simple things but the basics are the same.

Base on Dade's suggestions, I tried to create an object with displacement and apply a volume shader to it, if that's work I can create a new mix shader that has displacement. displacement will affect the object and volume will be applied to it, in the user's perspective it will be a volume that can support displacement.
The only issue I faced right now is the volume in LuxCore is not as solid as Arnold volume and the render time is different.

Note:
Technique was developed/pionired by Lee Griggs few years before it hyped & was popularized.

Re: Volumetric render ....
I think that's a different technique called Xgen topology. What I used is volumetric displacement.kintuX wrote: ↑Tue Jul 06, 2021 7:37 am Note:
