Description
This 3DS Max tutorial will help you create realistic, volumetric, clouds using a Particle Flow Source (PF Source), a procedural opacity map and a 3D object.You can read it on our webpage here
We'd love to hear your opinion.

While this doesn't follows my rendering phillosophy (re-create phenomena as they are, avoid "tricks" when possible, what would mean using a real volumetric system for clouds) this approch is amazing with the quality it produces

I completely agree. We've tried other options but they really weren't feasible.
On the other side, this tutorial does produce volumetric results. The billboards are positioned based on the base geometry's volume.
The problem is actually randomly generating clouds based on RL physics.
Mind you, if you're interested, you can create a gravity and wind dynamics reactive, spherical particle cloud. You'd then have to use maxScript to "place" the clouds and a super-computer that could handle hundreds of thousands of small spheres. You'd still have to use ambient only light so poly angles are ignored (so ray marching will still be faked)
If you're really interested, we recommend this essay by MJ Harris . It's quite technical and a bit on the long side, but it'll give you a good idea of the whole process.
Hope this helps.

Thanks man this is a good contribution!
Do you know if it will work with VRAY?

You're welcome. It will work with Vray (or the scanline). It's just a matter of preference.
