Thank you so much! For such large scale sims, I use upwards of 1024 resolution and the scene is usually built to actual scale. For realistic white foam, first, the number of foam particles should be a lot like in millions (I usually target upwards of 1 million foam particles per frame, and for some of my sims, I used 50 million foam particles per frame as well). Also, I have a bit of transparency in the foam shader so that it behaves more like foam and less like particles. Hope this helps.

@@blendercinematic thank you really much, that seems obviously heavy, does can flip fluid use gpu to render ? and also can you open viewport without crashing? sorry for the amount of questions, this is really fascinating work.

No worries. Yes, I use GPU to render. For viewport, I usually keep the display of particles and surface to minimum for faster response.

Thank you!

Yeah. I have to try that at some point. Thanks!

Thank you!

Sure. I’ll keep it on my to-do tutorials list.

Thank you!

Thank you!

Haha. Thank you so much!!

It is possible to punch a hole into the metal using RBDLab metalsoft. The official RBDLab studio channel has a tutorial on this. Regarding importing sims to unreal, I’m not sure as I haven’t done it.

Please ensure you are using RBDLab v1.5.5 for Blender 4.1

@@blendercinematic I just noticed I have 1.5.4

It’s an older tutorial, re-edited and uploaded.

Thank you so much!

Of course, the obstacle mesh should always be manifold (watertight). Try duplicating the mesh and use decimate modifier to reduce the mesh density and if necessary edit the mesh to make it manifold and then use this proxy mesh as the obstacle in the flip sim.

Furthermore, it looks like one part of the white water is under the sea. I can't think of any good solution 😭

I haven’t had a chance to try this yet but adding a displace modifier to the foam with the ocean displacement maps as texture might help.

@@blendercinematic Thank you so much! Everything went well😭

Adaptive subdivision only works with cycles and experimental features need to be enabled.

Thank you!

Thank you!!

I wish all tutorials had such an excellent description in their video's. Thanks for the info. Now I have finally an idea about the speed of a photo realistic animation 🙏🏻

Yes, correct. Thank you!

It’s on my list of tutorials to do as soon as I find some time.

Thank you!

Happy to hear that! Thank you!

You’re welcome. On systems with lower specs, higher dicing rate numbers such as 2, 4 or even 8 pixels can be used for render and viewport under adaptive subdivision of render settings.

Please watch the complete tutorial for which the link is in the pinned comment.

The bake files are huge. The procedure is multistep but user-friendly.

There is an option of ‘remove mesh near boundary’ under FLIP fluid surface option. That should be enabled to get fluid surface.

@@blendercinematic thanks❤

You're very welcome!

Thank you!

Thank you. Its on my to-do list of tutorials.

Glad it was helpful!

For the ocean material, please take a look at my ocean tutorial.

​@@blendercinematic Thank you

Try extruding the circle out and then make loop cuts in between. That way you might not have any triangles.

I haven’t tried it yet.

I have never seen that. Maybe resolution of the exr files or adaptive subdivision need to be increased.

You’re very welcome!

The buildings are from city builder 3d addon. I used particle system to scatter them on a plane. We can also use geometry nodes for scattering.

Cool. Just use static object as a source for smoke emission.

For high res bakes of over 1024 domain resolution, the bake took about 15 hours.

@@blendercinematic what cpu and gpu?

I mentioned it in the video description.

Sounds good. I’ll make a tutorial once I find some more time in my schedule.

I have plans for a tutorial as soon as I find some time. Meanwhile, if you need some help, you can contact me on discord, the details of which are on the about page of my channel.

Thank you!

@@blendercinematic by the way, there is a problem I'm facing in which the smoke isnt behind the wheels its all over the place like a big cloud engulfing the car. Do you know if theres a way to reduce the smoke properties?

🙂 Thank you so much!

It should be available but I guess flip fluids v1.6 is built for newer versions of blender, so I haven’t checked its compatibility with older versions of blender.

which version youre using? @@blendercinematic

Blender 4.0.1 with flip fluids v1.7.4

i got the solution, but my scene isnt creating much white water particles, csan you share your setting of ship scene @@blendercinematic

Please contact me on discord or email.

I usually use the ocean modifier as explained in the tutorial which is by extrapolation. I haven’t tried looping.

@blendercinematic I understand, thank you for the reply👍

Thank you so much! You can contact me on discord or email, the details are on the about page of my channel.

Thank you so much!

Please see the pinned comment for complete tutorial link.

Thx

In the shader editor, under mapping, is the type changed to texture?

In the shader editor in image textures thick boxes cyclic and auto refresh. Work for me.

Thank you so much. I agree. This is one of the first versions and I haven’t dialed in the scale properly. I’ve been working on refining the sims over the past year. Stay tuned for the updated ones.

The obstacle is not moving. Instead, the fluid is moving against the obstacle by using ‘inflow’ and giving it a velocity. Also to get the fluid surface as a plane, there is an option in flip fluid surface ‘remove mesh near boundary’. This gives a plane instead of fluid volume. Hope this helps.

@@blendercinematicThank you this is very usefull for closeup shots

Thank you for asking. I’d like to as soon as I find some time. I made this video about 2 years ago. I learnt quite a bit over the last few years and there are so many things I’m doing differently now for high res large scale sims that it would warrant an entirely new video.
