[RELEASE] Calm Water

Hey,
sorry for the delay, but I made some tests and the workaround does work with bloom and realtime emissive, here's a screenshot

 

That looks just awesome Sir, thanks for testing and showing. Since i'm relying on certain terrain shaders, i'll just cutout some meshes from the terrain and overlay them on terrain where i need it, and apply some self illuminent to those for same result, but it will look just great.

Maybe a good idea for an update to implement your fix as a feature. -CalmWater, now with glow 8)

- Have a pleasent day.

 

btw: waterplane maker script was a nice addition, i work with a bunch of terrains stitched together for each scene, so i have a lot of different sized levels and that just made it a whole lot easier for me to make them. 8)

sorry about the editing in this post, having issues i'm trying to pinpoint...

 

We're currently improving our integration with water assets in Landscape Builder, does CalmWater come with prefabs and does it support scaling of the mesh plane? (I see others have asked about scaling too). As LB works over multiple terrains, one method we use is scaling, and another is mesh duplication (which is less desirable). We let users create landscape wide "oceans" and then let uses easily size and drop in lakes, ponds etc.

 

I would say yes and no. It works overall but you will have 2 issues.

First, the tiling of the normal map and the foam is in UV space so you will need to adjust the tiling of those depending on the scale of the mesh. It makes me wonder if I should put these in world space instead....

Second issue will occur only if you use Displacement feature ( Gerstner wave or Sine Wave ). To get correct fresnel reflection I have to recalculate the vertex normals in the shader and I did not figure out how to include the scale of the mesh into calculation yet. So in the worst case the fresnel would appear as if the mesh was completely flat.

I do include a script to create custom meshes with the size you want on the fly though if it helps?

 

Hi Mr Verde. Is there a chance that the features on this will be added to CalmWater at any stage? By that I mean the raising up of the water in realtime? Thanks.

 

Hi,
no it's a completely different system. It would probably be a different package as well.

 

If you only want to raise the water, can't you just move your water plane in Y direction ?

 

Hi,

We are looking for a water shader for our mobile game. It needs to have blending at edges, ability to change color to dark swamp color, depth and it should look like the water is flowing.

Please let me know if this shader will work with our game on mobiles with optimal FPS.

Target platforms are iOS, Android and Windows.

Thanks,
Nikunj.

 

Hi,
is this swampy enough?



As for optimal FPS, it's not the cheapest shader, especially since it uses depth which will double the draw calls in forward rendering, but the demo scene runs fine on Iphone 5s and up, also on Nexus 5 first Gen.

In an upcoming release I will include a cheaper version of the shader but probably won't include depth or distortion.

Thanks!

 

Hi, It's looking great.

But how will it work with backed lights. Shall it require real time lighting ?
I am working on animation story of crocodile, As we are targeting mobile devices, I can't use directional lights.

Regards,
Nikunj.

 

Hi,
As is, if you have absolutely 0 realtime light then specular reflection would not display, but everything else will work.
You could set one Directional light's culling mask to affect only the water layer to have specular effect. Since it's calculated in the base pass of the shader anyway it would not change the performance.

Regards

 

WIP
Upcoming feature, Depth Fog.
When enabled you will have a slider to determine the translucency of the deep water.

 

Hi,

Thanks for reply. Finally we impressed with this asset. and we purchased it, today.

Now, as I mentioned, We are working on animation story of crocodile and monkey. I seen your read me file and followed the instructions but sadly I am unable to achieve that quality that you shown in previous shot of swamp.

So, I need guidance from you to achieve that quality. See, reference screenshot below:
https://drive.google.com/file/d/0B34u11VFCKb2b0RIMHpWeERhT3M/view?usp=sharing

better if you provide screenshot of the shader parameters. And also need step by step instructions to integrate this asset into my scene.

some of doubts that I have:

1) Is it necessary to use terrain or other ground model below the water plane ? Right now, I put a simple plane object of unity, as a water. you can see in reference screenshot.
2) Shall this asset runs on windows phones ?
3) In island scene, I can't see water. Shader is 'calm water (double sided)' on water plane.

I will contact you through mail, with invoice details.

Regards,
Nikunj.

 

Hi,
I will help you the best I can.

As for general setup:

• Since you are targeting mobile I assume that you are using forward rendering. Therefore you will have to add the Camera Depth Mode script to your main camera.
• Be sure to have your normal map's texture type as a normal map in the import settings
• Don't use unity's plane for the water. The water needs a scale of (1,1,1) for better displacement effect. I supplied a tool to create a custom plane the size you want in case you don't have a 3d modeling software.

The parameters I used are pretty much the same as in the pond demo scene with some color changed and I deactivated the foam.

1- Yes you need some model under the water plane otherwise it will not have the depth effect I showed you before.

2- As I mentioned before I never tested this on windows phone and have no way of testing it.

3-
- But it's working in the pond scene?
- Are you sure it doesn't have the DX11 material? (DX11 version won't render on mobile it doesn't support it)
- Is it giving you any errors?
- Unity version?
- Shader Version?

Regards,
Yan

 

3-
- not working on pond scene. Water object is pink.
- I am checking on Unity editor, not on the phone. Shader name is 'Calm Water [Double Sided]'. This is happened in two shaders i) Calm Water [Single Sided] ii) Calm Water [Double Sided]
Other two shaders having no issues.
- no errors
- Unity version 5.2.1
- Shader version - latest (I downloaded today) 1.5.6

You have my email info, as I sent you mail.
Please help me with this. Can you share screen shot of parameters of that shader?

Which shader is appropriate for mobile, out of your 4 shaders?

Regards,
Nikunj.

 

Hey,
If the plane is pink it means that there is an error or there is something missing. Check of you see errors in the inspector when you select the shader files. If so try to do a reimport on the shader folder.

It's weird that you get DX11 version to show but not the other ones, it should be the opposite.

I will send you a screen shot when I can.

Thanks

 

here's the screenshot, on unity 5.2 Android mode.

 

Hi,

Pls look at the shot, I set the same parameters as you did. but, not able to achieved the result.

Thanks.

 

After importing the asset, I got following warnings:

Lightmap snapshot 'LightingData' is inconsistent - 6 files out of 24 are missing. Realtime GI will be disabled. Please rebuild lighting for this scene.

 

Hey,
You are using the DX11 version, this is not supported by mobile. Please use the non DX11 version. Also remove the mirror reflection script, you don't need it when using cubemap reflection.

The lightmaps warning that you are getting is caused because I built the lightmaps with a different version of unity, but won't affect the water shader.

Thanks

 

(Sorry for bad english)

Hi,

We just bought this plug this morning and it’s really great !

We just have a problem after building the game :
Shader error in 'CalmWater/Calm Water [Double Sided]': undeclared identifier 'UnityDecodeCubeShadowDepth' at UnityShadowLibrary.cginc(97) (on d3d9)

Can you help us please ?

 

Hi,
Sure I will help you, what is your unity version and targeted platform please?

Thanks

 

Thanks for the quick answer !

We use Unity 5.3.3p3 Personal and it’s for PC Windows.

 

I cannot verify at the moment ( on the bus), but I think I fixed this issue in the next version.

As a workaround for now try to go in the shader file you are using and set the lines #include "UnityCG.cginc" to be at the top of all #include lines for each pass.

If you contact me by email I could also send you the 1.5.7 package.

Regards,
Yan

 

Awesome ! It worked !

Thank you very much

 

Hi,

Finally I fixed the issue. It was a version problem. I was using Unity 5.2.1 and I upgraded it to Unity 5.3.4

Water is working fine.

 

Cool! as you can see in the previous post it's possible that you get an error when building. I sent an update for approval, but I can send you the package by email if you need it now.

 

Hi,

It was shot from the editor but when I tried to build for Android, water is disappeared!

Unity version - 5.3.4f1
I am getting 3 errors from shaders, look at below screenshots.

 

Hi,
Looks like there is a bug in CalmWater 1.5.6. Good news is 1.5.7 has just been approved and should fix this issue!
I just tested it on unity 5.3.4p3 and been able to build on android no problem.

Regards

 

Unity Ver 5.3.4f1

Any clues?
Shaders are unmodified and updated to latest. Target platform is Windows/Linux x86

 

Should I upgrade the new version of calm water? I am using Unity 5.3.4f1

 

Yes, it should fix the problem.

 

Humm, I opened unity in DX9 mode to try it. I never tried it before as it was in the DX11 category. But still, I got the error as well when I built. Also the water doesn't show up in deferred rendering ( I think this is a bug on unity's side, my depth texture is all white ... )

Regarding the error you can do this, replace the line v2f o = (v2f)0; with this code: v2f o; in CalmWater.cginc

I still have some errors at build time, but was still working in the build on d3d9 in forward mode.
The errors I still have is due to shader limitation in d3d9, to fix it you need to turn off either the foam or the fog for now. I will maybe try to create the foam using the world coordinate instead of the mesh's uv. this will same me one input and you should be able to use it on d3d9.

I will also investigate more for the deferred part.

Regards

 

FYI, I made a quickfix for this. It's now d3d9 compatible and will be available in the next release. Contact me by email if you need the fix now.

Regards

 

Hi thanks for working on this. I am trying the DX11 mode.
I have noticed sometimes.. that the amplitude(and frequency) of Gerstner displacements needs to be really small.. like 0.005 and other time, I build/run it, and it seems the water is not moving at all.. I increase the Amplitude to like 10 and it starts working again.. (Dx11 double sided, latest Patch release).
I think its basically, an edit/play mode thing.. in edit more.. the values must be really small.. but in playmode they must be large..

 

See images, Water1 is in playmode, water2 in editmode.
Same size mesh, and scale.. just playing and not playing.
If i change the water to the large size, and stop, then unity hangs alot, and the mesh its drawing is huge, goes off the screen. So i have to hide the water gameobject, and set the shader down to a tiny size, then it looks normal again, hit play, and the water is flat.. ! (Increasing it up to 30 fixes it and we go round and round)

 

Hey,
Humm that is weird, I tried to build latest release in unity 5.2 and 5.3.4 myself and don't see any noticeable difference between the editor and the build neither from the play / edit mode.

Can you try this in an empty project with the demo scenes to see if you get the same result?

Thanks.

 

Ok will do

 

@YanVerde - Does this shader work in Unity 5.4 b16? Thanks.

 

Hi,
Quick answer, it should be. I tested only up to b12 as you can see:



One user did report some weird issue like it was working in one scene but not in an other one, but I wasn't able to reproduce it even after trying on multiple computers.

Anyways, I will try the latest beta later on to confirm.

 

Thanks for the quick reply.

 

Hi @YanVerde - One more question. Is CalmWater compatible with opaque image effects such as rendering fog and clouds over the water? Thanks.

 

Yan,

I have two questions. I want to update the asset but when I try it doesn't work. What is the best way to update the assets so it works?

Do you have any idea about why the mirrow reflection script could stop working on the console, although it was working before?

Regards,
Carlos

 

Updating with the new version of Calm water gives me this error from the get go:

unrecognized identifier "SurfaceOutput"

I am working on a Xbox One built

Any help very much appreciated!

 

Does anyone has the problem I am having with the real time reflection in the water, that suddenly doesn't work? Any work around? Some times it reflects and some times it just doesn't. Please if you have any advise about this, I am in a deadline

Regards,
Carlos

 

SurfaceOutput? Looks you are on a pretty old version of calm water. You will need at least unity 5.2 to update to the latest version from the asset store.

If you already are on calm water 1.5.8 maybe you still have old files that conflicts with the new one and should delete the calm water folder and reimport from the asset store.

 

To avoid errors you should also exclude the water plane from reflecting itself. On the mirror reflection script exclude the layer which your plane is in from the reflected layers.
