Problem with molotow-cocktail - liquid through wall

[Sascha Selent]

yes,some notification is really missed. or we can try to improve the blending to work with adaptive grid

Can you improve it till tomorrow?

[Ivaylo Katev]

can't promise, it's relatively hard

[Paul Oblomov]

and therefore I would have to retime them all at once - which is not managable

I don't get it. You have your animation just like it should be animated. Right ? Then you add fire on top and to simulate fluids slo-mo you change the play speed. Why you need to retime whole scene ? I suppose you object animation already slo-mo ? In that case you can animate sim timescale.

Or just try to abandon adaptive grid in max, make your sim with fixed grid, but lower the resolution (if simtimes are quite high) and export velocity - now, if you have maya version of phx you can resimulate (really fast, for the grid, you're having now) your max sim, creating feel of hires simulation. It is a bit tricky with smoke, but fire should be not a problem.

I thought that was a joke...

Ouf, Ivaylo! Ehm, I don´t know what to say. If you can do that it would be really really amazing...

...and for sure a really cool enhancement!

At the moment I try to change my setup - and it will simulate for a very long time. If you can tell me more tomorrow I would await this...

And again thanks for your support.

Hi Paul.

I suppose you object animation already slo-mo ?

No, because I have a MassFX-sim with breaking glass - therefore many objects. I baked them into one pointcached mesh - which is not usable for PHX-sim because of deforming geometry - but which I can use for slomo. So I need the MassFX-sim to influence the PHX-sim.

Or just try to abandon adaptive grid in max

This is what I try now...

...but the best would be if Ivaylo could solve that problem...

[Ivaylo Katev]

ok, try it tomorrow, i did it, but is very weak tested, expect troubles

Thanks Ivaylo!

I modified my scene using only non-adaptive simulators. It´s simulating right now - if it works fine (seems to be at the moment) I´ll tell you, so maybe it is not necessary at the moment to start an alarm - especially if troubles are expected.

But nevertheless it would be very very useful in the future to make this working.

[Sascha Selent]

Heeere we go!

Hi everyone.

Ooookaaay, I finished the scene - quicker than I thought, because all the heavy stuff was non-adaptive already.

Here is the preview:

Now I can control eveything to slo-mo and it works quite well. And it looks really cool!

Something that I noticed is that pulsing when the scene is very slow - good to see at the big fire flash. I´m not sure if this is due to the extreme slowing - or if this pulsing is a real-world-effect. I would think that it is due to the extreme slowing.

Do you have any ideas how to get rid of that?

Best regards.

Sascha

Simulate slo-mo with timescale.

[Ivaylo Katev]

Something that I noticed is that pulsing when the scene is very slow - good to see at the big fire flash. I´m not sure if this is due to the extreme slowing - or if this pulsing is a real-world-effect.

that's why the slow motion can't be used down to very low values. however, it works better if the difference between the frames is lower, so make the simulation as slow as possible during the simulation.

Yeah, thought that. Anyway, for the moment I can live with that, theres is no time resim with slower timescale. It even looks cool.

I´ll keep this in mind for future sims - where I first do all slomos in an client-accepted scene and after acceptance I do the sims...

Btw. Is it possible to crank up the framerate by say 10 - then sim - and when I then set the framerate back I have a 10 times slower sim? This way I don´t have to retime everything in the scene. I could the set playspeed to 10 to resync everything... - ...and then I have enough footage to play around with the timing...

?

...but maybe it is better then to sim in a prepared slomo...

[Ivaylo Katev]

this is the same as just set time multiplier 0.1

[Sascha Selent]

this is the same as just set time multiplier 0.1

Not quite the same. Setting the time scale to 0.1 I have to retime everything else in the scene - thousands of MassFX rigid bodies that shall influence my sim...

[Ivaylo Katev]

yes, this is a different story

[Paul Oblomov]

Setting the fps to something like 200 won't solve your problem of retiming ?
