The Community Ocean Shader (Open Source) Unity 5

I haven't tested it on 5.4.1 yet.
I am sure it has to do with the Inspector GUI code.
I will dowload it and get back to you.

 

Cool. It worked fine for some time and suddenly it broke. Then tested it in a new project and after a few minutes it broke again

Edit: I found a way to reproduce this. When i move the ocean folder to a subfolder it breaks. But when i move it back to the root directory it works again

 

I saw now your edit.

In the OceanGeneratorInspector.cs file there is this line:

presetPath = Application.dataPath+"/Ocean/Editor/_OceanPresets";

This is to load/save the ocean presets.

Change it to:

presetPath = Application.dataPath+"/YourNeFolder/Ocean/Editor/_OceanPresets";

 

Thanks that solved it

 

Hey, I've converted the BuoyancyInspector-script to use SerializedProperties, so it will save changes correctly and also work with the undo as expected. The modified script is attached.

 

Hi. Thanks!

I will include this in a small next update along with serializedProperties for the OceanInspector.

 

Where is the source code of libocean.so?

 

Hi.

There is currently no source code for the native libs.
These are created by me and actually do low level stuff.

 

OK. Thank you very much.

 

Hi elias,

My sailing game based on this beautiful community ocean is going well but I have a problem

Why my terrain doesn't create waves at shore line with the ocean? I am trying to build the game to Mobile. Can it be a limitation that I am not aware of?

Sample gif below:

Hi.

I am on the process of updating the lib. That will include a camera rendering the depth for the shaders and not using the _CameraDepthTexture since it is inconsistent between Unity versions.

What Unity version are you using?

 

Unity 5.4.2f2 , also I have tried with using my own mesh instead of terrain and it is not working (as waves) either.

And while you are redoing the lib, the scale of the boat is another weird thing with the shader. I guess it is about physic calculations though. Anyhow I just enlarged everything and buoyancy is working as intended with random bugs that I will iron out myself.

In conclusion, still this is 5 star perfect. Lots of people commented on great sea at my prototype Kudos to you.

 

The buoyancy to work correct you need a higher resolution mesh grid.
I could add some interpolation for smaller grids though, so that users can keep their ships or boats at physical dimensions.

In general I have more time now to work on the lib.

 

Hi, alias_t
before, i thank yo very much for community help.
I have a question with you:
i 'm creating the ocean by unity but i use own wave not FFT because i want interact with the ship. I only use your shader for my ocean mesh but in my ocean the foam at the wave not indecator?

 

Hi. There are issues with the camera depth buffer after unity 5.4.x.
So I am rewriting parts of the lib and the shader now.

 

Thank you very much! Elias_t
After i use your shader, the ocean is attach file.
Could you review the image and give me a idea?

 

Ok. I understand what you mean now.

The foam on the waves depends on the internal wave generator. Search in the Ocean.cs on how it is added on tangents.w.
So you should provide a way to do the same in your wave generator.

 

Thank you for your reply! Elias_t
Add tangents.w for sine wave is difficult. So i think, i want to use all of your ocean and shader. But i consufuse that if the your boyancy to add to ship, is it realistic dynamic of the ship? because my plant is small marine simulator. My ship is handling by joystics for pollusion and rudder, and other ship is moved by constant speed and course.
So, can i contact with you by email?

 

Hi. The buoyancy script should be fine. I have to change it though for smaller objects.

You can contact me through email. Check your private messages.

 

Hi elias_t:
Thanks so much for your Ocean shader. I have some question about the shader is that if there is possible made of underwater FX in this shader? Especially for Mobile platform too.I had been try many underwater FX package but can't actually run in good FPS so if there is a way to increase the underwater shader I will appreciate for your help.Thanks again!

 

Hi. I am rewriting now the system.
An underwater effect should come after this.

 

Thank you for your reply ! Elias_t!

 

Are there instructions somewhere on how to incorporate this into our own projects?

 

Hi. Select the main assets of this project and its dependencies and create a unity package. Then add this to your project.

The demo scenes should help allow you to understand how things work.

 

I posted this already in what seams to be a long dead thread to this topic:

I managed to get the Ocean running in multiplayer.
To achieve that i made the following changes to Ocean.cs:

• I added a System.Random object, which is initialized with the same seed on every client
• Time.time is replaced by the variable snycTime, which is synced with the server

In addition to that i initialize the ocean on every client simultanious (but I'm not sure that is still necessary).

In Boyancy.cs i put all the Code from Start() into a separate function, which is called after the ocean is initialized. Otherwise the script wouldn't work, because when the ship is created the ocean is not yet there.

Here are some videos of my game which use the Ocean.
It is still work in progress and the videos show not the network stuff, only player vs npcs

The videos are made with Unity 5.4. With 5.5 i have the bug, that the shore-foam and the one on the ships hull is gone.
But in the demo scenes it still works

 

Hi. Thanks for the feedback!

There is a known issue on unity5.5 on how the _CameraDepthTexture is used in shaders.
Right now I am rendering the depth into a rendertexture to avoid such issues in the future.

 

I made a short video to show my networking changes of the ocean in action

 

I got rid of the studdering of the waves over the network by using a different syncing method:
Not the snyct Time.time value is used in the client. Instead i calculate die timedifference between the Server and the client once and then use the clients "Time.time + timedifference".
Everytime the syncing is done i calculate a newTimedifference and compare it with the old. If they differ over 0.1 seconds, the timedifference is updated to the newTimedifference.

This way the waves are smooth and there should only be small corrections necessary which will be hardly noticeably.
The 0.1s threshold is tweakable if that is not the case.

 

Thanks for the extra info!!

 

Thanks for your great work elias_t !

But this plugin get error when archive project in XCode due to lack bitcode support

Here 's XCode error :
bitcode bundle could not be generated because '/Users/EmobiDev/Projects/FPSFreeze/XcodeProject/Libraries/Ocean/Plugins/iOS/libocean.a(ofVec2f.o)' was built without full bitcode. All object files and libraries for bitcode must be generated from Xcode Archive or Install build for architecture armv7

Can you rebuild these static lib to add bitcode support?

 

Hi. I will upload the bitcode enabled lib in an hour or two.

 

Ok. I have updated the repo with the bitcode enabled plugin. It is the libocean.a-iOS-bitcode.zip archive.
By default the libocean.a lib is not bitcode enabled. You have to unzip the previous zip and replace the libocean.a file.

In case you don't want to update from the repo, here are the files as attachments.

 

Very nice! I'll give this a try!

I dont know what happen but when I build without assetbundle,it's succssed and there is no error to happen so I guess the assetbundle doesn't maintain the ocean shader? I look forward to your apply. Thank you for your response anyway.

 

Hi. Your issue comes from unity.
This is the problem: WARNING: 0:4: extension 'GL_EXT_frag_depth' is not supported

Other users report it here: https://issuetracker.unity3d.com/is...-depth-is-not-supported-when-running-on-gles2

A user at stackoverflow had this solution:

Hi elias_t,

Thank you for your excellent work on this project. We've been using it for a simulation in our class for a Virtual Reality sailing teaching tool for ocean navigation, using the HTC Vive headset, the Oculus Rift, and the Microsoft Hololens. However, it was pointed out by our professor that the textures for the ocean surface do not correctly render in Stereoscopic 3D at this time.

My understanding is that this requires the texture to present a different copy to each camera eye. https://docs.unity3d.com/Manual/StereoscopicRendering.html has a (brief) overview of the requirements. I know this isn't a current focus of your work on this project, but I'd be interested in working to help bring Stereoscopic support to this library.

Thanks for your time.

 

Hi this is something that I have heard for the 1st time. I mean the different copy of the textures for each eye.
In that case you could create copies of the textures involved (they are 2. 1 normal and 1 foam) and create a new material for the second camera.

 

hi, I am totally new user in unity. I want to animate ocean like this. How can I work with your program? I download it but I did not find scene to open it.
Thanks

 

OK, I'll work on seeing if I can get this to cooperate, and will create a pull request to the github repository if the results are successful.

 

Hi. In the "Assets\Ocean\Scene" are the example scenes.

 

I got weired effects when there are transparent objects on or above the ocean.
At some camera angles they just dissapear.

I also found a solution:
In the ocean.shader i added "ZWrite Off" in each subshader. That solved it.

 

I'm sure you're sick of hearing this by now, but I absolutely LOVE this ocean! I was using another before (a very popular one who's owner deleted their blog and stopped supporting it), but found that that particular one didn't work with the HTC Vive at build-time. So I did some searching and stumbled upon this one. It works perfectly both in standard Unity projects and in the HTC Vive one I have. Thank you so much for making this available to everyone.

 

Hi. Thanks! Good to know that people actually use it.
And good to know about the Vive also.

In the next days a roundup update will come with bugfixes and later a bigger update with shadow support etc.

 

Today I found another "bug" which seams to be intentional but has strange effects in my game:

In the boyancy-script, the gravity is set to false when the ship is not visible in a camera, and there is no boyancy calculated.
Since in my game the ships are moved by forces, they begin moving very strangly until they are caught by a camera again. Sometimes they even begin to fly!

So i added a line in the update() function of that script that sets visible to true all the time

 

Hi. This is intentional. In case you have many ships, it is a simple occlusion method.
You can simply comment out the lines that do that.

 

Hi does anyone know how to increase the tile count. I can't find the code and typing in higher numbers in the slider input box just resets to 15.?

 

Hi.

The logic right now is to have the max number of 15 tiles. Which means the max number of tiles in each x or z direction.
I will try to enable higher count.

 

Cool thx would somehow increasing the tiles really effect the logic if it already scales with tilecount?

 

As it is right now, the tilecount influences the lod levels.
I have to separate those to make this work the way you want. Will see ...

 

Tried a few changes but nothing changed Found the gui slider increased that from 15 to 50 then did a find "15" and changed all those values to 50 but the tilecount in play remained the same .Oh there was one change that cirle around the tiles was situated further out.

Elias another question on the tile size it has 512, 30 ,512 what does the 30 for y do and would reducing it have any effect on performance. Thx .

Oh and the ocean is great in general so not dissing it in any way just have a huge world with high elevations and want to be able for the player to not see beyond the edge could use fog otherwise i suppose.
