UNDERWATER EFFECT. DIVE IN!

SEA HUNT - DOWNLOAD ANDROID GAME (MADE USING EASY WATER)

It contains:


- Simulated sky reflection (Texture / CubeMap) Easy to make with your own skyboxes. Unity's skyboxes reflection included)
- Opacity adjust
- Distortion map slot
- Specular adjust
- Gloss adjust
- Reflection strength adjust

- Adjustable animation
- Color input
- 2 texture slots
- 2 respective bumpmap slots

It's designed for NON Unity Pro users and mobile developers, although some Pro users may have a boost in performance since it has simulated reflections.

Attention: Although it runs on MOBILES, the performance depends on its hardware. Some devices have high resolution and not enough GPU. That's why this package contains different shaders with qualities from low to high. I'm always trying to optimize the shaders. Please, if you test it on your mobiles, let me know.

Any bugs or sugestions, let me know!

Hope you like it.

 

Very cool!

 

Looks great, I'm quite interested, but...

What is the performance like on the first generation iPod and iPhone 4, if the water was to take up the whole screen?

Thanks.
David.

 

I have the same concern as ddeaco. So what's the performance like on iPhone 3GS and iPad 1 when the water takes up the whole screen? (eg. on top-down view). Can you give us the break down from profiler (Draw Calls, CPU usage, frame rate...etc)

 

The water itself has only 1 Draw Call with only one "Render Type: important" light, and 2 Draw Calls with 2 or more "Render Type: important" lights.
For your other concerns I'm gonna make some tests and come back with more details as soon as I find some friend who can lend me iPhones or iPads. iPad was not a selling sucess around Brazil, so it's gonna be hard for me to find one.

I also forgot to say, it does NOT work fine with OPENGL ES 1.x.

 

Bought!
Life gets really easy with this one

Thanks for this great asset Grespon!!!

 

Thanks, Clandestine.
There was a mistake with texture2 and bumpmap2 speed's names. It's already corrected in version 2.1. It also contains a new shader for lower specs hardware.

 

Bought!!

 

Hello,
could you please have a demo that doesn't constantly move the camera?
thanks in advance

 

I have a problem with this asset, just bought and it works really cool when i'm testing inside unity.
The problem is when i test on the Ipad, the texture is dark and all messed up, please help.

Some images of the problem:

 

monosapiens,
Sad to read this. I'm gonna check what can be happening.
By now, try this:
Inside Inspector, uncheck 'Generate Mip Maps' for Distortions and BumpMap textures.
Tell me if it works.
Also, did you test the EasyWaterLow shader too?

 

Yes, same result on Android. This isn't mobile compatible yet. Even using the WaterLow shader.

 

I'm using EasyWaterLow shader and the uncheck "Generate Mip Maps' didn't work, it got the same problem. I'm only purchased this water shader because it says that works on mobile devices, since i'm developing for IOS and Android.

Please help me to solve this problem.

 

Well i'm willing to refund you guys. I see I still need to make more tests before stating it's mobile compatible. But I have to solve this issue anyway.
Unity 3.5 seems to have a bug with PVRTEXTOOL for some Mac OS's and i'm not able to test for iPhone or iPad until it's fixed.
For Android, it's smoothly working with my Samsung Galaxy Y. My stupidity to think it would be compatible with all devices.
My apologies. As soon as I return home I'm gonna work on it.

 

I'm willing to help you if you need any testing on IOS devices, this water really looks amazing with very low CPU cost, and really don't want the refund . Our game is still under development so i can wait for the fix.

Obs.: Se quiser, entre em contato via email para conversarmos. - rodrigo.na@gmail.com

 

EvilDingo, can you tell me which Texture Compression did you use when building?
In the Player Settings, what configuration are you choosing (Device Filter, Minimum API Level, etc) ?

 

I used whatever the default is for texture compression. Which textures need to be set to not generate mip maps? Device filter is ARMv7 only. OpenGL ES 2.0. 2.0.1 API Level 6 minimum.

My device is a Galaxy Nexus. Very recent model.

Also would rather help get it working than get a refund.

 

Thanks for supporting!
EvilDingo, try building with ECT1 Texture Compression, and Device Filter ARMv6 with VFP. See if this works, please.
I don't think disabling mip maps would help but if you wanna try they are: DistortionMap, DistortionMapLow, waterBump and UnityWaterBump.

 

Is this for 3.5 only?

 

No change using those settings, unfortunately.

 

EvilDingo,
I uploaded the version 2.2 yesterday. It may be approved today in the next hours. One of the shaders (the high one) worked on monosapiens's iPad 1 (with low FPS, by the way). Can you try it too?

 

Version 2.2 is up!
Let me know about performance with mobiles and possible issues.

 

I tried this with High and Normal shaders and on my iphone4 it's totally unplayable. Low shader is a bit faster, but still unplayable fps drop. It is even slower than Smart water mobile.
It is possible to use it on a big plane, for open sea for example? (if X,Z scale is 1000 instead of 1)?

 

Fillbiker, I've just made a little change in the Low shader and I raised about 12 FPS in my tests with Samsung Galaxy Y.
A scene with a full screen water, with a skybox appearing behind it and 2 directional lights, raised from FPS 50 to about FPS 63 with no quality loss.

I'm looking forward until Apple approve my Developer Program so I can start making tests with iOS too.
I'll try to release until tomorrow a new version with a collection of shaders, from the pretty lower until the high one.

And yes, it's possible to resize the plane or even to use the shader with whatever mesh you want.

Edited: I've just sent version 2.3 (maybe up tomorrow). It contains the correction I told above. It also contains 7 shaders. I hope it will fit everyone's needs.
Notice there is also a DistortionMapLow inside Textures Folder. It's set as texture, not normal map. It can be faster.

 

Version 2.3 is up already.
It has 7 shaders from lowest to highest.
I know it's not fully mobile optimized. I'm gonna wait until I can test on iPhone to start making changes. Maybe next week.

 

I just bought this, and I must be doing something wrong because I see the water surface and the skybox reflection in the relevant shaders, but I don't see any water motion at all. This looks nothing like the demos. I installed the example mesh in my scene but it shows the same problem.

I'm running Unity standalone on a Mac. Any ideas? Since everyone else seems to be able to get this to work, I must be doing something stupid.

 

Well, I think one stupid thing you could forget do to is to raise the speeds. Did you try all the shaders?
I'm gonna try it on my brother's Mac tonight ok?

 

I did both of those things!

But actually, I tried it again and now it's working. I suspect that there was something wrong with the way I added the easy water material to the mesh the first time. Whatever it was, it seemed to screw up the operation of the shader even in the example mesh.

But I tried adding the example mesh today (without my original mesh) and I saw motion. Then I tried adding the material to the first mesh I tried (a river mesh, so it is quite large) and it also seemed to be working correctly.

So I don't know what happened the first time I tried. I might have forgotten to take the original water material out -- that's my best guess.

So, everything seems to be OK. As Gilda Radner used to say, "Never mind!"

 

I'm relieved!

 

Any update on the mobile performance? I'm so looking forward to this

 

Looks great, I might have to pick this one up in a few weeks. Would it be hard to sink the waters movement to a server. I don't think it's really necessary unless I write a wave system. I'll still probably pick this up soon, (after I get paid).

 

Hi, I'm having a small issue on iOS, on the new iPad, that I'm hoping might be a quick fix. Here is a comparison between the Desktop and iOS. The iOS water seems to look "scratchy", almost crosshatched. Do I need to use a different compression or something for the iOS version or is this a shader bug?

iOS first, then desktop

 

jhmax720,
Well, I made some changes since version 2.3. There is a no Color Input for every shader now, so we can use it when publishing after applying a colored filter with any image editor. Also, some codes were simplified.
The sad thing is that the highest quality shader (EasyWater7) is still running slow on iPhone 4S. It runs fine without the retina display but it looks a little pixelate.

 

Chase Cobb,
I was testing on iPhone 4S, and maybe it was happening too, but I couldn't see because the pixels are too small.
I'm gonna check it again today when I get back from work ok?
For now, try changing some parameters in the Inspector for the textures and BumpMaps.

 

I tried every combination that I could think of, but with no luck. I also changed the quality settings for iOS so that I know its not cutting the resolution of the textures. Hopefully it something simple.

 

Chase Cobb,
In 4 hours I return home and I'll try to fix it ok?
I must have changed something in the new release.

 

No rush. I'm not about to release this title or anything. Just trying to test how far this water can be pushed.

 

I'm new to MAC,
It seems crispy in the Editor too.
Anyway. I have to stop working now. I'll try to fix it tomorrow.

 

On my Mac Mini it looks normal, its only scratchy on the iPad/iPhone for me.

 

Looks great but...

FOR GODS SAKE, please just slap a character controller in there and let people control the camera.
Moving is too fast, fixed is too low to the water plane

 

Humans .. always making demands...

Okey, I'll do it when I have time!

 

You know you can play the scene and swap over to the editor window and move all around the scene while looking at the current water effect. The speed of the uv scrolling and the intensity of the normal maps depend on the size of the plane you're using for the water. Thats why they are adjustable I would imagine. This guy is working hard for us to have VERY inexpensive water, cut him some slack.

 

Unfortunately, I'm not where I can use the project. Once I get to my home pc, I can check it out. I was just using the webplayer!

 

There's a new WebDemo available.
I'm using a texture from cgtextures.com. I think it's far better than mine and it's free to use in your games.

 

An issue was found when using Camera HDR with EasyWater7 shader and maybe others.
For EasyWater7, a palliative solution is this:

-Remove line 201

-Change line 202 to:
fixed FinalAlpha = 1 - _Opacity;

-Change line 19 to:
_Opacity("_Opacity", Range(-0.2,1.0) ) = 0

Doing this, it will remove fresnel for opacity and this will affect the whole element equally.

 

Grespon, i have a question about your shaders.
First about pragma 3.0 it looks like my PC card dont support it, and i belive all Android devices dont support it too.
I bought it and i see only black surface, the same on android, tested on HTC Desire HD (android 2.3.3) and Asus TF201 Tegra 3 (Android 4.1).

Any idea how to fix this so i can use it?

 

Head@Hunter,
What's your PC graphics card ??
Don't you have Directx9 ?

Most Android and iOS devices support Shader Model 3. Even iPad 1. I'm pretty sure your Tegra 3 supports too.
For PC, even the lower Geforce 7 series supports SM3.
You're the 1st telling me about this black surface so I believe there's another thing going on.

Well, one thing I really forgot to do is to declare #pragma target 2.0 in the lower shaders (EasyWater1 to 5), since they don't need to use SM3. This will be made in the next release, but you can easily do it changing the line around number '40'.

Try it. Let's see if you can run with pragma target 2.0.

 

Ok i will try and post screenshot of result.

UPD. Declaring #pragma target 2.0 helps, thanks! It work great now.

 

Chese cobb,
The 'scratchy' problem is happening with my iPhone too. It's probably happening with all iOS devices. After 3 days making tests and researching, I think the problem goes deeper. IPhones (and maybe iPads) doesn't handle very well large tiles when there's uv scrolling. The included example itself is too tiled for iPhones.

I think there's no fix for this. BUT there is a turnaround. If you need a large plane, instead of raising the tilings, make several planes and tile the elements side by side. It's easier than it sounds, actually. And I think it's the only way. (if someone have a better idea, i'm hearing)

I'm working on the next release, and I'm really considering making the uv scrolling by script (not by the shader). I don't know if it's gonna solve this iPhones limitation problem, but it will give more freedom.

I'm also considering making cubemap reflection slots, since some people were asking. Cubemap costs performance but gives a better reflection map.

 

What happens if the camera goes into the sea? Are there any underwater effects?
