Viscosity test Realflow

[claudiostacciarini]

Hi!
Viscosity test with Realflow. Corona 1.3.

[BBB3viz]

This is strangely enjoyable.

I'm trying to do the same on another object, but like chocolate! I like the honey effect ;)
I have one question..when I set the max number of passes and I start rendering the animation there is no fluid moving, it's like all the first frame..but if I play the animation in the viewport the liquind moves..what can I do? Thanks

Hi JacopoGrosso,
I had the same issue with that too! If you render 100 frames you just get 100 frames of frame no.1!

I used a script i downloaded i don't recall the name but here is the script....

The script renders each individual frame, works for me!

...Hope it helps you.




--function to make a single digit number into a 3 digit number by prefixing 0's. Returns a string.
fn tridigit digits =
(
   if digits.count >= 3 then
      (
         print "Digit already greater than 3 numbers"
         return digits
      )
   else
      (
         if digits.count == 2 do return ("0" + digits)
         if digits.count == 1 do return ("00" + digits)
      )
)

-- close the RSD

-- set it to single frame

Thank you very much, I'll try it as soon as I'm at the computer, I'll let you know! Maybe you saved my life ahah

Hi JacopoGrosso,
When you import mesh in Max, sometimes the solution is start with frame 0001 and no 0000, because frame 0000 has "no mesh", and I think this cause a problem in Max to read the other frames.
I export/import alembic format and think is a good solution , but I will try the script that anbirks show below.

Hi antbirks, thanks for script, I will try here! :)

........

I created a txt document (notepad), saved, changed extension from .txt to .ms
After in 3Ds..I imported all (animation and meshes .bin) and saw the same problem..tried to run the script but every frame I had to press OK on the tab that was appearing, saying "error creating file output", so I pressed 100 times OK ahahah

What I'm doing wrong? :(

EDIT: Ok now it works, I set the animation and the save folder and it starts rendering every frame, thank you very much :)

MY PASS:
1) set frames, folder where 3ds saves
2) run script
3) done

You're welcome!

I'm glad i could be of some help. It took me a while to realize the issue and find the script that works.
