realflow renderkit: fix the intersecting transparency issue?

There was a pretty long thread about the intersecting transparent object methods, (http://www.maxwellrender.com/forum/view ... s&start=45) but it never occurred to me to check into the Realflow renderkit. Does that get around the intersection problems for things like fluids in glass containers, or does the rendertime mesh still create the same effects on lighting/refractions?

No. It doesn't help in that area. It just meshes at render time instead of using pre-meshed bin files (to save from having to store GBs of mesh files).

Okay, thanks Brian!

No problem. I too am still hoping/waiting for a good solution!

You can use object clipping in the mesher inside RealFlow which will just cut away the meshpart btw. RFRK can have an object clip as well but will substract the particles and close the mesh on the clipped area while it calculates.

Does the object clipping in Realflow provide a clean boolean effect? That would provide all that is needed for Maxwell wouldn't it? If so that should be the standard approach, wonder why it hasn't come up before?

Tks Aniki.

I wish Maxwell could do this at render time behind the scenes so no extra mesh work would have to be done. Some kind of detection and correction of normals of intersecting transparent objects that have different nd values.

That would be ideal - not all meshes are going to come out of Realflow so that mesh clipping is only a partial solution. Ideally the interface stacking issue could be resolved so that the intersection just isn't an issue (like the way Vray does it) but I doubt that it will work. None of the unbiased render engines I have tried use that approach so it must be difficult or not possible.
