The Community Ocean Shader (Open Source) Unity 5

Great job Elias!!!
I will download and play with it

 

Yeh, I meant the mesh of the boat. I have another question though.
Obviously this is Ocean, but if I want to use it in archipelago the waves are to long. Is there a way to shorten the waves amplitude? It look superb when I see it as ocean waves, but then I have to scale up everything else to unreasonable numbers.

 

I figured it out. You really should not answer my questions or more aqurate I should not bother you with stupid questions.
This is very nice.

 

Hey, I asked a question a few weeks ago. I'm having a problem with white lines appearing around objects in front of the ocean. This only occurs with the shore foam turned on. I can't figure out how to fix. Can you please point me in the right direction, or just say you don't know because I don't know if you even saw my question.

 

I tested by creating a new project in unity and dragging the water prefab onto the scene, along with another object. When I played the scene, the problem still exists (white outline from foam shader). So there is nothing specifically wrong in my main game. I also tried loading the test scene into a new project, the problem persisted. Only when I run the demo scene, inside the demo project itself, there is no problem. It must be one of the settings in the project then, but I can't find it. Disabling anti-aliasing in the fixes the problem in all projects, but that is not a "solution". I checked, and it says anti-aliasing is enabled in the demo project, but the problem does not occur, so there must be some other setting causing the issue.

 

Im pretty new to game development, or programming in general. thought i would ask here before i waste to much time on this. Is it possible not render the water inside of a floating object? Like having a ship with interior without being flooded with water.

 

The fishing boat demo, has an extra deck mesh with a shader that hides the ocean.

 

Oh sweet, missed that. Thanks.

 

Hello everyone,
was just giving the asset a try and loved the results out of the box.

Now, I am trying to get a good understanding. I will preface by saying I just got into Unity programming and am yet to dabble with shaders.

1. The Ocean: basically an empty object with the Ocean Script and shader.
2. Objects are made buoyant using Buoyancy or boyant script

I have yet to tweak the settings to get an indepth understanding but I was playing around with trying to replace the ocean shader.
Tried using the one made by przemyslawzaworski

https://www.shadertoy.com/view/Ms2SD1

(The latest file and executable present in comments)
The Repo https://github.com/przemyslawzaworski/Unity3D-CG-programming

It doesn't work. I am sure it is because of my lack of understanding but was worth giving it a try

 

I will take a look at it, but keep in mind that these are some expensive shaders.

 

Thanks!
I know I am punching above my weight but I generally try to fiddle around to get a hang of things.
I appreciate your response.

 

Hi guys, just wanted to notice that this is a great piece of work and I'm in awe of your effort on this project. I guess I could just figure this out by myself, but I appreciate if you could just point me in the right direction with this. I'm trying to use it in civilization-like map as a basic shader for the ocean. I don't need the physics part of it, or underwater effects, just the water movement. So I figured I can just take the shader and material from your repo and use it on my mesh to achieve that, but can't get this to work. It seems I should also use Ocean.cs script, but I think that will drag other dependencies and so on.. So basically what I'm asking is can this be used as just a watersurface shader and what is the minimum I should add to my mesh to achieve that. Or is this simply impossible without using the whole project and your editor component?

 

@elias_t was probably talking Less about that and more about the fact that you will be very lucky if you get any realtime game to run those type of fragment based shaders at a good framerate.

 

Yes. No point of having the whole project for this simple thing. I will try to make a light project only for plane water.

Hello Elias,

Me and some friends are making a new game using the community shader, but we have run into some problems. We would love to use a mesh collider instead of a box collider, because it will help us stablelize the boat. We are making the game together with the oculus rift.

We have tried a lot of different solutions, but without any luck. Do you might have any idea on how to enable the usability of a mesh collider, instead of box collider?

 

Hello. Yes it is doable if you modify the buoyancy script.

There is a simple slicing loop that adds buoyancy blobs to the blobs list: blobs = new List<Vector3> ();

Modify this to add blobs to a desired hull or mesh.

 

please excuse my ignorance, but i'm kinda confused it which repo should i follow ( and potentially contribute to )

Thanks bud!

 

Hello Elias,

As I said in a previous post, you did a very nice work.

I've found a problem using mobile phone, there is like a cut between certain planes, there are in a different height.
Did you realize of this problem?

I will upload a picture as far as I can

 

The picture

 

Hello. There must be something going wrong with the code that shifts the tiles according to the camera position.

Hi Elias,

Do you know where should I check or change to solve the problem?

 

I'm on it. I will post a solution soon.

It is the calculateCenterOffset() function.

 

This is impressive, really ! With such a great performance - I'm stunned.
Only one little touch is missing - mesh deformation behind the boat for better feeling of foam / wake and some spashes in front and front-sides of the boat.
Some additional ideas - the faster we go the more and longer foam we are creating, bigger splashes and more deep deformation.
Also foam should be wider but less visible in time, same for deformation.
Question - is this also working with 2018.1 with this new HDR shaders ?

 

for that the easiest way is to add the ocean deformation to the decal and particles + offset, but that mean you need dense mesh for them. Or you can use a render texture decal of the trails projected into the ocean (screen space or topdown projected)

 

Elias is there any tips or tutorials for mobile? I did my best but couldnt increase the FPS over 30. Thanks for the awesome asset btw.

 

Set the preprocessor directives in player settings: NATIVE;THREADS and it should run faster.

 

Hi! I've been playing around with the Community Ocean for a couple of days now. It is quite the best water asset I've tried. There are still some issues I've experienced like square trailing shapes sometimes appear at the back of your boat and it is a little challenging to configure a boat with masking to stay above water at all times. If you have very turbulent waves, your boat gets submerged from time to time. So I think it would be better if a boat with a closed-off top design is used. I also still haven't successfully setup a really transparent water and splashing particle effects for my boat.

Anyhow, I also experienced your problem about the outlines for the player's boat. But when I dragged my boat prefab to the Target field of this Ocean asset, it seem to have disappeared and more water effects like mists and trailing foams emerged. Here is an illustration:



Thanks to all those folks who contributed to this magnificent water asset! I salute you all!

 

Question: Is there a way to actually make near the surface objects be partially visible with its actual texture slightly muted only instead of just having a white shape as below?

 

Hello Elias,

I'm doing my first videgame.
Could I use the ocean to create the sea?

Best regards

 

Wow, that is amazing! I hope that will be available as a Unity developer tool soon.

 

dayuuummm directing wave spectrum, interesting

 

Was now able to somewhat make near underwater objects partially visible at certain angles by tinkering with the Alpha values of Reflection & Refraction section in the Inspector...



Also, I think I found out how to fix the "lines" that appear when Cloudmists intersect the water. I just set Render Queue value to "Geometry" and Lightmap Parameters to Default-Medium. It made the Cloudmists less visible... but the lines disappeared.



One more problem I have now that I can't find a fix is how to hide the moving dark square shape visible behind my boat the first time the game is started. Anybody experienced this and can share some clues/answer?

 

Another method I used to reduce the outline is to apply Anti-aliasing to my boat using Unity Post Processing Stack.

 

Thanks for these useful info!

I tried Particles -> Standard Surface -> Fade with "Enable Soft Particles" ticked for the mists. But I noticed in my game, this caused a short stutter just before the mists gets loaded. Thus I might stick with the first method for now. Anyhow, whatever shader settings I used, I experienced a delay of about 50 seconds before cloudmists started appearing.

Sorry I missed your previous mention about the dark square patch and yup, it goes away but only after I move my boat away to a certain distance. I hope there was a way to actually hide this square patch on game load. Maybe by producing more foams as usual only in the initialization phase of the tile system... But then again, it seems the player must still begin moving away before the square patch can be covered up.

EDIT: When I added the lines "NATVE; SIMD; THREADS" in the Scripting Define Symbols filed under Edit -> Project Settings -> Player -> Other Settings (PC, MAC, & Linux), the dark square patch seem to have disappeared and I feel the game ran a little bit faster than before.

 

Wow. This is absolutely great, just downloaded and tested it from the github.

Please keep it up!

 

I am trying to update Ocean into an existing project with an old version of Ocean and run into an issue that was mentioned here 1 year ago:
when I click the ocean object, the editor does not appear. I get these errors:
Unexpected top level layout group! Missing GUILayout.EndScrollView/EndVertical/EndHorizontal?
UnityEngine.GUIUtilityrocessEvent(Int32, IntPtr)
UnityEditor.EditorGUIUtility.TempContent (System.String[] texts) (at /Users/builduser/buildslave/unity/build/artifacts/generated/bindings_old/common/Editor/EditorGUIUtilityBindings.gen.cs:325)

My procedure is:
move the Ocean and StreamingAssets Folders + the rsp and meta Files from the Downloaded Project Assets Folder into my Assets Folder.
Then open one of the demo scenes
The scene works
Click "Ocean" -> bang - error

Yes, opening the downloaded project works without errors. But I cannot begin from scratch with my project.
So how is this editor thingy working. Do I have to register it somewhere in the settings?
thx

 

I guess I found it: the Assets/Ocean/Editor contents has to go into Assets/Editor

 

Has underwater effects been included already? In case yes, how can it be activated? If no, does anyone have some tips on how to create it?

 

Played around now I've a white grid over the waves. Disabling grid in gizmo still the same.
Thanks

 

Can we have a screenshot and Unity version?
Thx.

 

@JamesArndt

Yes this could be done by using higher tessellation and modify the ocean mesh. But an intersection routine with the hull and the ocean should take place.

A distance field clip shader on a hull could be better perhaps.

 

Off course. It's free.

 

Hello.

Yes using NATIVE; SIMD; THREADS as scripting define symbols is recommended (simd will not work on mobile).
And it is actually much faster.

 

I was able to remove that by putting a big underwater square 2000x2000 under the surface.
