Note on : 14:25 Try this : In the "scene" settings, go to the "units" tab, see if you downscale the "unit scale" (From 1.0 to 0.0625 for example) it may solve the small sphere problem without you having to up the amount of iterations for the rigid body solver. (Which costs more in performance). Your issue i believe (Or blender's issue, is having floating points round-off errors when it comes to small numbers) there is a marginal error there in regard to precision with small numbers calculation.
yooo this is crazy hyper realistic water ever!!!!!!! MY GAD ... love it so much! super worthy with that price!!!!!! during this quarantine time best to see this kinda video.
Not with the way the Blender simulation systems are currently designed. Fluid and rigid body simulation systems in Blender are separate and cannot interact with each other.
Seems difficult to get something to either pop out of the water or a boat to Bob up and down without water running off of it. Thats what makes it natural looking. Everything basically seems water repellent
@@Blenderphysics-Videos yes, thats actually kinda sad...Blender keeps updating and adding on features but, some things are just stuck in the stone age. In order to get the better looking water simulations I think we could need to use collections and do some trick layering to get better looking results.
The current version of the FLIP Fluids addon (v1.0.7) is supported in Blender 2.79, 2.80, and 2.81. We recommend using the latest Blender 2.81 release due to a Blender 2.80 bug that could cause frequent render crashes. More info on Blender 2.8 support: github.com/rlguy/Blender-FLIP-Fluids/wiki/Blender-2.8-Support
Is it possible to have a source of bubbles coming up from below? Like if someone was exhaling a bunch of bubbles, or an air tank being ruptured? And if yes, can those bubbles interact with those on the surface in a realistic manner, moving water with them?
I struggled so much on the second method. When I increase the number of "Substeps Per Frame" setting in Rigid Body World, the ball starts to move ultra fast when hit by the fluid. And I hope it can be partially infiltrated. But I guess that's the limit of blender and ff wasn't designed for this.
My Rigid bodies work as they are supposed to, when I make the fluid a rigid body nothing happens, fluid flows through the objects, does not move them? Any idea why? Does it have to do something with the starting from beginning frame?
Found it, my scene is 800 frames and in scene properties the Cache "end" was only to 250 put to 800 now it works! thank you! now only if we could get the gpu to help render the fluid
I spent all of today trying out mantaflow in blender 2.82 and as of 28th jan 2020 it is still very buggy I lost many simulations when trying to change parameters and had lots of crashes. Then I downloaded the flip fluids demo and did the things I was trying in like 30 minutes (successfully with no crashes). If it scales nicely when my new threadripper parts arrive I will be buying a flip fluids licence.
@@Blenderphysics-Videos Ok ... do you know how to combine the ocean modifier with flip fluids like in this example ? th-cam.com/video/8imUXafSx-w/w-d-xo.html
Hey, im trying to make a scene with an iceberg. i make a small part of it separate from the big iceberg and slpashed into the water. im trying to follow the step 3 of the video but im doing invert cause i want the parts dive from above. however something is not working.. how can i make the parts just dive and interact with the fluid as the nature?. any advice?
Isn't there a way to have the splash go past the domain? like if I wanted to make a character create a big splash and have the water go on the ground or something.
One thing I'm thinking of that could possibly work is to have two separate simulations, disable the splash particles in a smaller simulation, and then making a bigger simulation which has the water particles disabled and simulates the splashes with a bigger radius. 🤷♂
@@Blenderphysics-Videos THanks！ I have to admit I am surprised by ur willing to answer more questions from me. well since u mentioned it. I do have more special questions related to the pay for blender artists. I want to know how do you blender artists price ur work? so far I know u guys have different fields, like modelling, shading, tracking, particle and fluid FX stuff, can I just hire one blender artist to do all the work or I have to hire different people to split the pay as well? is there a job position to calculate the price for a scene's VFX and hire different people to finish it so that we do'nt have to bother to deal with it? thanks for ur answer.
@@woolenwoods665 You are welcome! This depends on your needs. Most of the works you can see on this channel has been produced by one person. If you are looking for something special please send a request per mail to info[AT]blenderphysics.com - Thank you.
Just curious, what are/ were the specs of your computer in this video, and how long did it take you to bake with the resolution of 300 (if you recall). Thanks!
I haven't even finished the video yet and it's already the most useful realistic floating tutorial I've been able to find! Great work! Love it 👍
Thank you! :)

thx man, its totallllyyyy helptful!
i recommend using auto keying to fasten the key frame process
Good idea! Thank you!
a tip : you can watch series at Flixzone. I've been using them for watching all kinds of movies these days.
@Jadiel Emmanuel Yea, have been watching on flixzone for years myself :)
So is it not possible to ever have a dual fluid system with support for buoyant collision objects?
Not with the way the Blender simulation systems are currently designed. Fluid and rigid body simulation systems in Blender are separate and cannot interact with each other.
@@ryanguy4536 OK thanks.
Hopefully in the future.

I think it will take some more time for more beautiful results. For a tutorial, to show possibilities, the results are still okay.
@@Blenderphysics-Videos yes, thats actually kinda sad...Blender keeps updating and adding on features but, some things are just stuck in the stone age.

Hmm...So it looks like this version of FLIP FLUIDS now works with 2.8?

What you could try is to use a particle system, convert the particles into keyframed objects and use them as invisible obstacles.
@@Blenderphysics-Videos Ok, that's a great idea! Thank you :D

Maybe. Did you try it again or found a solution?
@@Blenderphysics-Videos I didn't. I was following this tut as a pratice. I give up.

Will flip fluids development continue now that Mantaflow will be in 2.82?
Yes of course! Some great new features are in development.
@@Blenderphysics-Videos Ok thank you, great to know!

Hello There
Hey, im trying to make a scene with an iceberg. i make a small part of it separate from the big iceberg and slpashed into the water. im trying to follow the step 3 of the video but im doing invert cause i want the parts dive from above. however something is not working.. how can i make the parts just dive and interact with the fluid as the nature?. any advice?
That is not natively possible and needs to be made using tricks.
Isn't there a way to have the splash go past the domain? like if I wanted to make a character create a big splash and have the water go on the ground or something.
No, the sim is always limited to a domain ;)
One thing I'm thinking of that could possibly work is to have two separate simulations, disable the splash particles in a smaller simulation, and then making a bigger simulation which has the water particles disabled and simulates the splashes with a bigger radius. 🤷♂
hello thnx for this amazing tut, plz tell me how do i make the water blue and make a video out of it? TIA
what can be done to make it photorealistic? now it is good enough, but it looks like animation.
There are a lot things that can be done.
It depends on your lights, backgrounds, HDRI´s, wetmaps, texturing ...
@@Blenderphysics-Videos thanks for the reply! really appreciate it !
@@woolenwoods665 Let me know if there are special questions.
There is no way to get realism out-of-the box.

i cannot remember the baking times. The system is an intel i7 k8086 with 32GB RAM.
Baking time could be something around 24h - not sure.
@@Blenderphysics-Videos Cool, thanks.
does it works with mantaflow?
I´m not sure about how obstacles will work with mantaflow- but yes, in theory this should work, too.
