CFL condition limited to 10?

[Jordan]

Why is the CFL condition limited to 10? I understand this is the amount of voxels the velocities need to travel before Fume does another Simulation step. Why is it limited?

Hello,


More than 10 voxels in a step could be unaccurate. I can increase this limit to 20 tops.
For previews, you can limit number of simulation substeps to 1 for faster sims.

Correct me if I'm wrong, but isn't it possible to "cheat" this limit by just keyframing the value and modify it in the curve editor to a higher value?
At least it works for vorticity.

cheers,
Fabian

Fabian, you are correct.
Values are limited in the UI and plugin does not perform any clamping internally (abuse it on your own risk ).

Nice! I was always wondering about this one! Actually it works very well, at least for vorticity! Just a thought on the new update, it would be great if you would allow a higher max value for the vorticity. Something like 3 would be great, this would help a lot for scenes with a low timescale. Although setting the value in the curve editor works, it's sometimes a pain to click through all of the parameters to see what your actual value is, instead of just looking at the ui.

Well, in some cases parameters can create simulation that are out of control so parameters are limited. Otherwise we would be getting many emails from angry customers

I think we can add some hidden MXS callback that will allow you to abuse it

perhaps an expert mode checkbox that takes these limits off and exposes the systemScale property

Yeah, that would be great! Perhaps with a little skull icon next to it.

Just write a script Jordan...I know you know how

Im just thinking of everybody else

[jrand]

haha, you Aussies are always so kind (I do mean that with sincerity BTW)

I like the skull and cross bones button idea! This of course would have to be a secret button, that is only accessed through a large combination of right-click, alt, ctrl, shft combos

[sitnisati]

John, now I am worried.
I am willing to add a general MXS parameter that will be named allyourbasearebelongtous that will unlock everything in FumeFX. Wait and see

[jrand]

... that will be named allyourbasearebelongtous

haha! the super parameter :VOPI I love it, Fume domination!

[FabianB]

I love secret super parameters! Haha that should be awesome! :M
