The really looks fantastic! Also supporting for marketplace

Hey people, and happy new year

I know there has been a lack of updates but I can assure you that progress is being done behind the scenes (slowly but surely).
Thanks to who is sharing their updated branch for 4.14 and helping with thread questions by the way.

I’m trying to find more time to work on the project but it keeps getting more difficult… which is why I’m thinking it might be a good idea to release my upcoming FFT as a new plugin in the marketplace.

You can think of the new marketplace plugin as an early access to “kickstart” the project, that way I will be able to put much more time to it, update it more rapidly and add more features.
Then later down the line I will open source it to the community. What do you guys think?

Here is a list with the core features I’m aiming at for the first released version of the plugin:
**

• based on Tessendorf’s FFT paper.

-Multiple spectra to choose from with many tweakable parameters (amplitude, choppy, wind velocity, direction, fetch etc.).
Phillips and Unified Directional spectrum currently implemented.

-Foam generation based on the spectrum.
Tweakable parameters: foam amount, coverage, decay rate, dissipation.

-Infinite system using Quadtrees (video)](watch?v=l6TZvTculb0).
Dynamically subdivides the patches for efficient usage of vertices.
Expands to the horizon (or up to given distance).
Frustum culling (removes patches outside the camera view).

-Custom BRDF shading based on Eric Bruneton’s paper.
BRDF model suited for rendering.
Added custom SSS (subsurface scattering).
Planar reflections (custom component) which can be tweaked in the shader.

-Interactive water heightfield.
Allows for dynamic interaction with the surface (as in watch dogs).
Can be layered on top of the FFT waves (square around the camera will be simulated) or used as stand alone for lakes and puddles.
Boats leave natural looking wakes.
Multiple propagation algorithms to choose (MuellerGDC, Tessendorf iWave and more).

-Underwater post process .
Waterline (camera- intersection).
Light absorption / fog (new method).
Volumetric Godrays.

Many more features planned for later updates.**

I don’t have an ETA yet but hopefully early year.

And as always, a screenshot

is how the custom BRDF currently looks like (shader still far from final, wip).

Hey @

Thanks for the update. The screenshot looks great!

May I suggest you to add the marketplace plugin AND keep the project open source?
From many posts I found here, it seems there are a bunch of users eager to get a ready-made package for user (target customers for a marketplace plugin) and a bunch of us who like to hack away at the plugin.
For example, I’ll probably need to make it “simpler” on lower end configurations, because my target audience probably won’t have all the processing power required to have the shader and a bunch of other going on. (is something I’m still considering, though)

Since you don’t have much time to work on the project, it might aid people brave enough to dive on the code to fix the project in case of a (necessary) engine upgrade.

Talking about code fixes, can you take a look at Pull Request ? There are more fixes at my fork that I can submit if you want

Btw, I’m willing to help with the plugin if you need a hand

I am going to branch off 's latest and clean out all the content that isn’t required for the to work, including the TOD items, art content, audio, etc. Good to finally get an update on the progress and that the progress will be sold on the Market. I hope Epic buys from you and makes it apart of the engine would be great if Nvidia and Epic could get a great fluids system into the engine. Thank you for all the great work !

You just need the Plugins folder to make it work, the rest are examples of use

, I will not buy nor support without the source. It’s just a liability in my opinion…being dependent on a non open source plugin and having to wait/hope for an update when a new engine version is released possibly losing the entire investment…with the source at least we have a choice to port it ourselfes. Also I think marketplace is a better option than other solutions, it’s just a more convinent way to download/maintain.

Perhaps I miswrote it a little bit… I did not meant that the marketplace version will be binary-only (without the source code)! that would be ridiculous indeed xD
If you pay for a plugin then it should absolutely include the source code so you can modify it as you like.

What I was trying to say is that after a period of time I will release the plugin (for free) on or otherwise.

I will try to merge it in the repo when I find some time

The plugin idea sounds great, as I have no idea how to implement the shader at the moment, even tho I have been follow post for a long time I have no clue to what file is need and where to put it
so a plugin from the experts sound brill.
I have bought all the water shaders and blueprints that can be used in UE4 and all of them have no crashing waves, and no beach/shallow waves if that makes sense/
And would love to see option.

screen shot looks amazing,
And thank you to all that is supporting project, great work…

[Sitrec]

Would definitely support project if it was released on the marketplace. Hard work that benefits the community should be rewarded.

[anonymous_user_90eee5dd]

plugin? Please with and Vulkan support.

[ConceptualTrap]

Hey TK,

Is there any of getting a more user friendly method for masking the water surface out? I’m specifically thinking of smaller boats where the water surface clips through the hull walls? I’ve struggled with , on and off, for months with no simple solution.

[Carnivoris]

The camera on the ship seems to be broken. Is there a fix or workaround? I see the workaround for a camera glitch that Epic needs to fix in the blueprint, but the camera still doesn’t seem to look at the ship properly. I’m in 4.14, if that matters.

[jaijai76]

Is there a tutorial on how to setup and customise an ? I can’t seem to find any here on in the project files.

[ghwlanglois]

YES MARKETPLACE PLUGIN PLEASE!!! OMG that would be so

[anonymous_user_92cd4149]

+1 For plugin, will buy it for sure

[Alpha-16]

No compatible with 4.14 ?

[n00854180t]

@AlphA-Fr;650122

No compatible with 4.14 ?

Look back through the last few pages, there’s a 4.14 compatible repo.

[darkok25]

Someone knows how to fix sea shadow problem ?

[UnexpectedSquirt]

+1 for the marketplace idea. Your screenshot of the FFT waves looks amazeballs! You would definitely have my cash in a heartbeat

[Derjyn]

One of the biggest things I loved about , was it was an open community project. Going the paid marketplace path… I’m gonna have to disagree with else on . I also loved that competed with the paid stuff on the marketplace and felt that it pushed those selling stuff to do better. I wholeheartedly feel there should be an open version of , at the very least in tandem with an “easy” paid version for the weak-kneed out there. If you are serious dev, you can work with . If you just want some plug-n-play action and code and/or more than 20 minutes of work scares you, then pay a few bucks.

Just my 2 cents, as a long time user of beast.

How much will sell for on the marketplace? I’m looking for a good shader.
