Blender FLIP Fluids - Rogue Wave in Large Water Flume

- Rogue wave forming in the flume of a Large Water Flume. Modelled and simulated with Flip Fluids in Blender. Edited in Davinci Resolve.
This is a major project I have been working on and off for the last 2 months. I was intially inspired by HD1080ide's video ( • Rogue Wave created by ... ) about a rogue wave that was simulated in Germany's Large Water Flume (GWK) research building.
The environment seen in the video was fully modelled by me using textures from polyhaven.com/textures and creating some other procedural textures, using the invaluable resources of Ryan King Art: / @ryankingart .
The building is based on the Germany's Large Water Flume: www.fzk.uni-hannover.de/en/th.... I couldn't find any blueprints or floor plans to model in reference to. As such, I had to resort to use HD1080ide's video as my main reference, modelling everything by eye and guessing some other features.
This has been a really big project for me in the past 2 months where I learned a lot more about modelling techniques, texturing, lighting, and many more 3D techniques. I plan on posting a breakdown video in following weeks, but I first need to properly learn Davinci Fusion and how to use the different render passes I did. I hope you enjoy this video!
Render information:
Baking:
For first 500 frames out of 1250:
Resolution: 1000
Voxel Size: 7.781cm
Voxel Count: 10 703 000
Baking time: 11h33min
Bake file size: 230Gb
Rest of 750 frames:
Resolution: 1250
Voxel Size 6.225
Voxel Size: 20 880 000
Baking Time: 12h27min
TOTAL BAKE TIME: 23h50min
Bake Size: 76.6gb
Rendering:
Scene 1, 2, and 4 were rendered at 256 samples with a temporal denoiser. The rest was rendered at 512 samples with Super Image Denoiser.
A total of 3050 frames at 30fps were rendered for this video.
TOTAL RENDER TIME: 163h18min
Initially, I wanted to render all scenes with a temporal denoiser, but I only realized mid way that it disabled blender's motion blur and only allowed for vector blur after. Since I wanted to take advantage of the better motion blur, I decided to render the rest of the scenes without a temporal denoiser and higher samples instead. This resulted in some flickering in the fences and textures in the background.
Observations:
What worked:
- Really nice strong wave hit the wall for a good splash effect.
- Environment added much needed realism and believability to the scene.
What did not work:
- Because of the long and narrow domain for the fluid, increasing the resolution was very expensive in performance which limited me in what I wanted to achieve. The final simulation's resolution is quite lower than what I would have hoped.
- Some weird whitewater artifacts on the water as a result of a too low resolution.
Changes for the future:
- I'd like to explore more opportunities with the environment and other ideas with the Large Water Flume.
- I want to overall improve the simulation by having a higher resolution and improving how the wave forms and breaks.
Personal score: 8/10

This is unbelievable realistic. Had to watch it for three times to get that this is a render ^^ Really great work ma man :D
amazing quality seems the real one, when it started i thought OMG they have finally cleanded the tank!
I have to say for a rendering this is absolutely stunning work
didnt even know this was a render until i read the description
This is so mad impressive keep it up
Really well done.
Very well made....Keep up the great work.
I love it!
Wooooow
Wow!
impressive!
Ok wait a second. I'm 28 and I always had eye for the random videos on the internet mimicking real life but this time I was really bamboozled. I had to read the comment about the "wet cement effect" to understand that this was not real, LOL
Yep lol, everything you see here was 3D modelled and rendered. There is no real footage composition or real life elements. The water is probably the part that looks the most "off" to me, especially with the weird foam on the side, but that was both a technical limitation and an error on my part. Glad you enjoyed it!
@@SirMaxiimus I was the same, for me it was the little details like weathering on the piston ram thingy etc. really really well done matey!

It's good yeah, but you could immediately tell it was animation from the perfect crest of the water. There is uniformity in nature, but there's still a stark difference between artificial uniformity and natural uniformity. Good attempt.
Amazing!! How did you get the wet cement effect?
The wet cement was done with a wetmap. Basically, the fluid acts as a brush, and the concrete as the canvas. So, as the fluid moves, it paints a map on the cement that can then be customized in the shader settings. This video goes in great details for the context of flip fluids simulations: th-cam.com/video/GYGNoTmZSN0/w-d-xo.html
This is soooo good omg! I legit thought the first few seconds were real footage.
Are you from germany?
Thank you! And no, I'm not from Germany lol, but I took a random interest in their Large Water Flume (GWK) facility and that made me want to try and recreate it in Blender.
@@SirMaxiimus oh xD
I’m still waiting for the “rogue“ wave….
What gave it away for me the camera shaking. It always looks so fake for some reason.
#wave
This was made in blender????
Yes sir!
What would the drawbacks be of rendering this with EEVEE Next in 4.1? It would be great if you could render a 10 second clip in EEVEE Next as an example....
That's a very good question. I'm not really sure. I've barely touched eevee to be honest so I'm unfamiliar with how to optimize it. I'm not too sure how it would handle reflections, but it would be interesting to see a comparison. Thanks for the suggestion!
@@SirMaxiimus I think you'd need to add a reflection probe
Why does blender exit when baking with flip fluids?
I used to have the same problem, but it seems like it has to do with how Blender handles its interface UI. To prevent crashing during baking, I recommend rendering my a command line. That's how I've been baking and rendering everything now. The FLIP fluids addon has a command line button available in the addon tab when pressing "N". I hope that helps!
