Gorgeous. Absolutely gorgeous. I watched the entire video but I guess you all in one tutorial shows how to apply this from scratch on a new landscape? I'd need to follow a tutorial on how to apply these splines on a new landscape and choose a river type that I like since I'm still a beginner. Already dug my river channel into the landscape, only need to know how to fill it with your beautiful river water

[@AndrasKetzer]

Thank you! There is no "automatic filling of holes" mechanism: I have placed a flat landscape, and quickly carved the riverbed with the erosion brush - then placed a river spline, and manually shaped it to match the landscape. Next steps are explained in the vid. This introductory tut might be useful for you: kzbin.info/www/bejne/rInEnZmIdtOLl80

[@KHos73]

So cool, will this work ok with a GTX 2060 3gb card ok? is it heavy on performance?

[@user-sq9xi6pz3l]

thank you very much. I couldn't figure out this plugin for a long time. I watched a lot of lessons. But I didn't understand anything there. Your lesson is the first in which much has become clear. I will continue to study it in several stages. But I need to figure out if the balloons can be turned into ships that float on the river. that is, how do I change their movement and animation and insert another mesh?

[@AndrasKetzer]

Thanks for reaching out! This all-in-one tutorial is essential: explains how to make meshes interact with ninja: kzbin.info/www/bejne/rInEnZmIdtOLl80feature=shared - the video also hints: by adding hidden intercting elements to your ship (simple boxes) you could define the ideal "shape" where your ship body is generating ripples & foam

[@originalShea550]

Holy cow, this is amazing. It looks almost too good to be true! How taxing is this system? Is this feasible for videogames or will it take up too much of the GPUs attention? Is this possible in combination with procedual generation? How would a spline handle elevation? Can it slope downwards or is it tied to an X level/sea level? Are drop offs possible..? Is this system compatible with volumetric water; for example assume you had an exact replica of minecraft in UE5, where water interacts in real time with the enviorment, flows, etc. I assume this wouldnt be compatible as its a mesh? (genius use of having the actual simulation following the player rather than in the world for some cases, really really smart.) Also, thank you for answering, I know i asked alot of questions. Truly your work looks amazing!

[@AndrasKetzer]

Not too bad: Stage 3-5 in this demo runs 80-120 FPS on GTX 1080 - and above 340 FPS on RTX 3080. Stage 1-2 are more demanding - around 240 FPS on RTX 3080. Of course.: by switching off caustics and lowering sim resolution, it could be improved!

[@originalShea550]

@@AndrasKetzer I appologize! I updated my question before I saw your response, Thank you for answering! Thats truly quite amazing! So in an infinite spline, or procedual generation,the simulation is only following the player? What would happen if multiple players were in an area together with this plugin?

For me, this whole fluidNinja reminds more of a tech demo/presentation. I understand it might be difficult and time consuming to learn that thing, but there is lack of any implementations tutorials-READY TO USE examples videos (ocean/ cool fire ) Or maybe I'm wrong? You should work on that, to grain more customers for your not so cheap product. btw maybe is there a way to pack this like unreal addon in future?

[@dobrx6199]

This looks great! Which of thse types is the most perfomant for the river?

[@AndrasKetzer]

Thanks for reaching out! - Performance is roughly the same for all river setups (~240 FPS on RTX 3080, UE 5.4). You could test it, see "Student Version" on the community server: discord.gg/rgEtwua2tu

[@dobrx6199]

@@AndrasKetzer sounds good, thank you!

[@lamsmiley1944]

It looks good, but I’d like to see variations in the speed of the flow of the water from the middle to the edge. The water on the riverbank isn’t going to flow as fast as the centre of the river. It would be great if you could set if up so there is a set amount of water flowing and the depth and width of the river determines the speed (that’s probably 5-10 years away).

[@AndrasKetzer]

(1) Ninja is using velocity fields - and this way: capable of handling the features, you are looking for. (2) on the other hand: we'd need distance fields to gather riverbank data - and DF is OPTIONAL under UE4 (off by default, and most users do not switch this on). (3) as a consequence: riverbanks are ignored, by default

[@MxT333]

Cant seem to get the landscape material working on a partioned open world. - It works fine on a normal imported landscape. but im not sure why the tag doesnt work on a landscape thats imported heightmap using the open world feature doesnt work. If I have a lot of landscapes in my world it eats up a lot of ram. but if set up using the landscape ue5 documentation you can get big maps loaded in sections. Then just setting the output material to multilayer (ie sand) to the whole landscape. Is there maybe a limit to the size of landscape or how its created?

[@AndrasKetzer]

Thanks for reaching out! Your conclusion is correct: ninja does not work with World Partition. To discuss the case and learn about the workaround, you could join the community server (discord.gg/rgEtwua2tu) or email me (andras dot ketzer at gmail)

[@chipimus9188]

does the river spline flow nicely into the ocean system for fluidninja live?

[@AndrasKetzer]

In case a splinemesh and a large planar surface use the same material: blend nicely. In case they use separate mats: users need to manually tweak the intersection to make it look nice

[@DeltaZavr.]

It possible to use on mobile, for example , on top-down game ? or only on top hardware?

@@AndrasKetzer Thanks, buddy, a year later! :) My feedback revolves around my limited grasp of how you execute your incredible work. Unfortunately, delving into the coding aspects isn't feasible for me as I'm an artist juggling numerous considerations like UI, wordscale, art style,, creation of textures and models, game sounds, backstories, quests, quest areas, and even the construction of terrain. I constantly weigh in on factors such as whether animations need to be faster to combat a sluggish game feel. My critique essentially boils down to, "Hey, the water looks fantastic with the import instance - just tweak some values, and the job is sorted. i know you prob put down insaine ammout of hours to optimize, tweak and create new things.

I bought this asset but couldn't use it because it is too complex and there is no constructive tutorials on how to make the basic things like river, waterfall, lake and ocean. The documentation also doesn't explain how to make them, only show cases and breakdowns. Too bad, this asset have a lot of potential but since it is too complicated to be used and need a lot of time and digging to understand how to use it, I decided to use the Flux plugin because it is way more simpler and its creator, made a step by step tutorials.

[@xTHHxAimiForevr]

how come whitewater works on objects like rocks and the player but not on the shoreline?

[@AndrasKetzer]

Hi! Ninja interacts with "point like" objects: mesh pivots, bones. Large meshes - like the coastline - could be channelled to the sim via Distance Fields. But: distance fields is OPTIONAL under UE4 (off by default). So, for compatibility reasons: we do not use it. As soon as we leave the UE4 branch behind / make ninja excusively UE5: we will utilize distance fields.

[@0fxeditz]

How can we change the normal for this water simulation I have tried but got no option to change the normal texture. That texture is just looks like panner node how can we get the solution...

[@AndrasKetzer]

Thanks for reaching out! (1) ninja output materials use TWO sources to generate the final visuals (including normal): (A) sim buffers and (B) a pattern generator, built-in to the material. This video snippet explains how sim buffewrs are used: kzbin.info/www/bejne/rInEnZmIdtOLl80 --- and this snippet explains the pattern generator: kzbin.info/www/bejne/iWbRZoemmZZ6odE --- (2) normals could be adjusted SEPARATELY for the buffers (in the outmat /Normals section) and and for the non-interactive patterns (in the outmat /Tilemap /Normal section)

[@0fxeditz]

But that is pre generated moving buffer but I wanted to add or manage my normal like I wanted to create the waves over the water. I don't want to make a round circle just getting round for infinity 😞

[@AndrasKetzer]

@@0fxeditz ninja generates normal, refraction, opacity... etc from grayscale density data - both for the interactive, finite sim and for the non-interactive, infinite tile pattern. For the tile-pattern: the grayscale map is user defined. In case you'd like to add a specific normal map instead: the "WorldSpace Generic" basematerial could be modified accordingly (/Outputmaterials /Basematerials)

Szia! Volna kedved hozzá, hogy együtt kifejlesszük az RTX-nélküli közel-realisztikus refrakciót? Ez akkor érdekes, amikor a karakter vagy egy tárgy félig vagy egészen belemerül a viszonylag csendes vízben (de a kamera a víz fölött van, persze). A heves hullámok, mint ennél a sekély pataknál is a videó elején, vagy egy túl mély víztest esetében, mint amilyen egy tenger, ezek elfedik a dolgot. Összeraktam egy know-how-t, egy matematikai-logikai lépéssort, de nekem se programozási tudásom, se hardverem nincs hozzá, hogy magam próbálkozzam vele. Írnék emailt, ha oké.
