hi again,
we're doing a little animation for the moment,
would like to hear your c&c's

Cool, really looks like creamy chocolate, congrats!

A little flickering at the bottom of the fluid, but that could be compression.

I would mabee expect the chocolate to fall in a less uniform way on the thing, (just the way that chocolate publicity showed it to me, cause I never saw the real thing)

[jonnybefree]

hi thablanch,
yes the flickering at the botton is one of my problems with realflow.
if i make the mesh more fine, the rendertime goes 5 times up, and the chocolat looks clumpy.
its my first project with realflow, and i think you must have a lot of routine and experience for a good workflow. its a little buggy.

[DaForce]

looks great!!, although given how fast the chocolate is being poured onto it, i would expect it to be almost covered by then end of that animation time.

[jonnybefree]

hi daforce.
yes thats want the client said 10 min. ago.
i'am working on it.

[RErender]

Hi jonny looking pretty convincing, for the flickering not sure what might work but the real mesh will work wth max modifiers applied I often use modifiers to optimize the mesh but in this case maybe vray displacement to subdivide it a bit more ?(btw Ihave not tried a vraydisplacement on realflow mesh :P )

[Da_elf]

realflow mesh does not keep its topography which makes it tricky for things like motion blur and im assuming it might make it weird for something like displacement. as for the huge mesh maybe you can play with the adaptive mesh detail (or however its called) inside RF itself before having to import to max. i dont like max's optimise modifyer too much. i find too realflows internal pressure might be the cause of it going on so slow. its like filling a glass. you can swear your pouring lots of liquid in the glass but its filling so slowly.

[jonnybefree]

hi rerender, i havn't tried it witch displacement, but i think a simple relax modifier would do the job.

da_Elf, when i increase the mesh subdivision in RF, the chocolat becomes very blobby, i think its the right way, but i havn't 2 two days for calculating it.

its a great try & error machine

[Aneurisma]

why don't you just fake it from the middle down?!...
it made me hungry though!

[jonnybefree]

how would you fake it?
ffd? hmm
i think i got it mas o menos.

isn't renderd yet, just a preview

[Aneurisma]

just an idea, since I can't try it out myself:

1) Export a coarser mesh from realflow and use subdivision inside of max;
2) use an animated bump noise, very fine and subtle, to give the feeling of laminar turbulence;
3) when you get to a point of the simulation where it's not going as well as expected you can get the coarse mesh and animate manually with some linked Xforms or bones...

you can reference to the begining of the simulation as for speed and consistency of the chocolate, but of course would be a lot better to set a perfect simulation and let it run!

By the way, I like the second try a lot!

[jonnybefree]

hi aneurisma,
thanks for the tip.
the deadline is today, so i think i will leave it like this, but when there is time again i'll give it a try.
anyway, realflow is really a great software, but for productions with short deadline it isn't stable enough i think.

so best greetings
jonas
