Creating an ocean - Appendix C: Splashes

[@methlokaijufan9729]

Is it possible to export the bifrost simulation as alembic cache?

[@jso19801980]

great pace and voice and everything else

[@AntonioPalmucci]

mmm...nope, maya 2020 doesn't work

[@RedaChekirine]

you are simply the best

[@Котлетон]

Thanks for a useful tutorial, but can you make a tutorial on how to blend ocean and fluids in flame?

[@damienvilleneuve1398]

Hi, I im facing a weird isuue, at some point, the emission region does something really weird. Is there a way I can share you my scene because I don't know how to explain?

[@edufx8722]

Excelente, ahora tengo que aprender inglés. 😁

[@Yiannio222]

I followed everything and nothing happens when the sphere meets the wave. I've noticed that the master voxel size doesn't change my liquid container i don't know if that helps you know my problem?

[@Autodesk_Maya]

Master voxel size wouldn't change the overall size of the container, but it will change the detail of the splash. What do you currently have it set to? Try to get that value as low as possible (if the voxel size is too big, no splash will happen since it will basically have 0 detail).

[@Yiannio222]

Maya Learning Channel I have it set to 0.150 like in the video :/ I followed everything up until the 3 minute mark and nothing happens

[@Autodesk_Maya]

@@Yiannio222 Just out of curiosity, if you create a Bifrost Liquid simulation by itself (without the ocean or guided simulation) do you get anything? Alternatively, were you able to successfully do part 4 of this tutorial (the dynamic wake)?

[@Yiannio222]

@@Autodesk_Maya Nope, i also get this message when i create the bifrost liquid 'cache disabled as unsupported nodes were found in the scene'

[@Autodesk_Maya]

@@Yiannio222 That's not a problem (it's a warning from the Animation Cache feature, which is not compatible with Bifrost Liquids so it automatically turns off). If you right-click the Time Slider and go to Playback Speed, is yours set to "Play Every Frame, Free"? You must be in this mode for dynamics to work.

[@Damich]

hi, is it possible to do a ripple effect as we did with the boat in the part three using the same process?

[@Autodesk_Maya]

You definitely can, but it will be a lot slower since it’s a full particle simulation.

[@sergekwamikponsou395]

hi the tutorial followed to the letter does not work properly. did you add foam? Are there any steps you forgot to add? at my house there is no Splash and when I leave the simulation started at Frame 1, we do not have the particles generated. but if I start at the frame where the meteor touches the surface, it works, without splashing. I await your answer. thank you

[@Autodesk_Maya]

When you say it works without splashing, does that mean the particles appear on the ocean surface but they don't interact with the meteor? I would try decreasing the Master Voxel Size and increase the meteor's Emission Region Thickness. Additionally, try slowing down the meteor a bit (just as a test).

[@crisantoIII]

I have Question on 5:37, the volume shader emission, where is it attached to? It seems been there before the start of the tutorial.

[@Autodesk_Maya]

Sorry, what do you mean by "been there"? Emission is a standard attribute for an aiStandardVolume, and is typically driven by heat. In this case, we're changing it to be driven by density instead (i.e. denser water = foam).

[@Yiannio222]

Sorry to be a pest but there's no aistandardvolume in my hypershade, there is however a bifrost foam material? Also out of interest i rendered before the addition of foam and no splash was visible on my render that's not normal is it?

[@Autodesk_Maya]

Do you have the Arnold Plug-in turned on (mtoa in the Plug-in Manager)? And do you have the latest version of Arnold installed?

[@Yiannio222]

@@Autodesk_Maya Ye i'm using arnold and its maya 2019

[@Autodesk_Maya]

@@Yiannio222 Are you sure there's no aiStandardVolume? If you type it into the search field, it doesn't appear? That seems very odd. If anything, I'd try upgrading your version of Arnold. www.arnoldrenderer.com/arnold/download/

[@Yiannio222]

@@Autodesk_Maya Nope :( theres 3 standard surfaces, bifrost foam material, and then the other normal materials and i'm pretty sure the arnold is up to date as i'm using my universities account

[@Yiannio222]

I just tried it on my laptop as well and still no volume? I haven't followed any other bifrost liquid tutorials before this would i have missed something?

[@christiansummers4318]

Do you have a tutorial for splash effects from objects emerging from the water like a whale jump?

[@Autodesk_Maya]

Unfortunately no, but the principle should be the same as this tutorial only running in reverse. In fact, you can just take the meteor_GRP and rotate it -90 degrees in Z to get a pretty decent start.

[@christiansummers4318]

@@Autodesk_Maya Do you have a tutorial about underwater scenes?

[@misteridiot123]

how can i cache the splash?

[@Autodesk_Maya]

You can use an Alembic Cache (Cache > Alembic Cache). Note that this will only work for the splash geometry, (so you need to turn the Bifrost Meshing 'on').

[@misteridiot123]

Maya Learning Channel I see. Thanks, I kept trying BIF.

[@krishnaa7416]

When My Liquid Particles are flying and again fall on the guided surface(boss output) the liquid particles are combining and forming a big surface... it is happening with in the next frame 37.... upto 36 frames the liquid particles are fine.... on 37th frame the all the comeback particles are forming a surface on the boss output... how to solve this... need urgent solveing... i'm trying to make a dolphin jump in ocean...

[@Autodesk_Maya]

I would try using a a kill plane or kill field to automatically delete the particles that hit guided surface outside the camera. Depending on the shape of your splash, you may even need to setup multiple kill fields. Remember also that you can animate them if you need them to move over the course of your animation.

[@krishnaa7416]

@@Autodesk_Maya The Actual Problem is particles are forming on the surface... Is there anyway without using kill planes... or is there any lifespan option to them?

[@Autodesk_Maya]

@@krishnaa7416 Yup there is. If you go to the emissionRegionProps tab, under the Emission section, there's a Death Age attribute.

[@AbyNeon]

it looks like shit and all of this water stuff is super long to set up and uses tons of volatile and non volatile memory...this solution is TOTALLY UNACCEPTABLE for such an expensive suite like maya......I honestly think that maya is a great suite, but without these features working 101% realisticly and easily, maya today shoudl be worth a 10th of the price....or else step up ur game to 2018 istead of offering solutions that are pre microsoft windows stuff.
