Realistic Water

Can this be made to work with a spherical planet that has a water sphere?

 

Alas, no.
Only the mesh, which has an angle less than 180 degrees.

 

Will this realistic water effect can be applicable for Android mobile?
This will give good fluidic effect for the pool. Good job sir!

Water worked on mobiles (but foam and depth not supported, because opengl es have problems with depth buffer)
You can see the demo for androin in description.

 

Oh k. Thanks kripto.

 

Thanks so much for the quick answer, kripto, solved both my problems immediatelly. (Was so happy about the quick reaction that I just bought all three of your Realistic Effects Packs too, need them anyway for the project. )

 

How about a way to define a new 'up' instead per mesh/instance? Then I could manage the spherical grid and instantiate each as needed?

 

I do not quite understand what you mean.
I tried using the sphere instead of plane. There is a problems with distortion in uv-unwrap.

 

Hi.
Is there any example of this used for large water plane, like sea or ocean? I need it for mobile ship simulator.

 

Hello,
The current version does not support ocean mesh (via projected grid). You can increase the size of the current plane, and create multiple planes in a grid. (Including using lod).

 

Greetings kripto289,

I have been considering this asset but had a question first. We use procedural terrain and unity water4 to make water in our game. Of course with their water we have issues and are looking for a different solution. Specifically, I wonder about reflections. With Unity water4, reflections do not work correctly because we have multiple pools of water throughout the world, also on different levels (rivers, waterfalls, shallow ponds and small lakes), and the water doesn't change color with the light changing color (day/night cycle).

With your asset, would reflections work correctly with multiple bodies of water in the scene on different levels? Even if reflections would not work it would still be in improvement over Unitys water4 which does not support changing light conditions, as your water changes with the changing light.

 

Hello,
I use reflection as well as the standard Water4 water.
I'll try to include ssr reflected in the next update (if I can understand how it works). Perhaps it will solve the problem.

 

Just tested the web demo and the tropical whatter really feels great.

BUUUt, I miss a couple of things that ruing a bit and not so bit the experience.

Soreside foam. Kmon! this is a must! otherwise the coastline feels really dull.

And some more advanced stuff like flowmaps as other package do have, this two things would make this a must buy assets.

 

This is foam.



You can see all water settings in the readme. https://www.googledrive.com/host/0B...G5fbGdsQUJ6OV9vaTBxOWNpSEFWM0hqMGc/Readme.pdf

I do not put readme in the description, because my english is not very good and readme is written in bad English.

 

This is looking better and better, @kripto289 - only reason why I haven't bought it yet is because I primarily need water for rivers, which means I need a flowmap of some sort, to get water flowing along river boundary. Anyway, great job! But you should post about and advertise your 2.0 release! Had no idea it was out already

 

This water is looking better and better!
Not seen foam like this before, meets the assumed appearance for shoreline foam in the picture.

 

Hello kripto289,

First of all let me say that this is the BEST WATER SOLUTION!!! for Unity hands down!. What a great product you have made here! I am very happy with it. I already tested it in XBOX ONE, so if anyone need the best water for Unity Console this is it.

Now to the point I need your help with. How can I remove the dark borders you see in the following pictures, left of the screen and bottom of the screen? This kind of looks weird. That is pretty much everything I had problem with.

Regards,
Carlos

 

Hello,
Can i have water material? I want test it.
Try to change "perVertexDistortion". For example "1000".

 

Hello kripto280,

How can I send you the water material? I will try the perVertexDistortion to a high number to see if that fix it.

Regards,
Carlos

 

kripto,

Here is the water material with the settings I am using for the beach. Keep in mind that my game has underwater gameplay.

Regards,
Carlos

 

I do not have this problem. Your material worked correctly.
You have same bug with default water settings? Try change other parameters?
Also, this bug on pc or xbox one? What a unity settings? (rendering path, directx)

 

Greetings kripto!

Love the asset so far, great new changes in the update.

I mentioned earlier that we have voxel terrain that is procedurally generated. I have many of the features of your water working well now but I have found two funny problems that you might be able to help me with. There is another level of voxel water generated along the ground below the water. This creates a water volume for our players to interact with

So as you see in the screen shot (not everything is enabled) The water looks relatively fine:


However, when I turn the camera and look at the same spot of water, from the opposite angle it looks like there are holes punched into the water surface:


I get this all over where water is generated. Upon closer inspection I can see the water surface is indeed there just as it looks in the other angle and I can swim on it, so it is a visual bug.

With Unity Water4Advanced water shader, this visual artifact/bug that looks like a hole in the surface does not happen - and so I took some more screen shots to illustrate the effect (it seems to be a render depth thing maybe, but not sure so I thought I would ask). Here is what looks like a hole on top of the water surface:


But it is actually water volume directly below, and for some reason is showing through the top - here I have stayed in the same spot and simply gone underwater:


I have noticed that anywhere there are ridges with the water volume being rendered below, at certain angles it seems to error out and show through the top water surface, making it looks like a hole in the water.



The other issue I have run into is that the water shows through the billboard LOD trees in the distance. When I was using the default water4 shader this would not happen, which makes me think again that there is some strange depth render issue here. I tried this in both my bare bones terrain package and my current game project and ran into the issue on both (both use the voxel terrain engine for the world generation). Thanks in advance if you have any idea, and thanks also for the great asset so far. In my game I have all the features working, and at certain angles when I don't get the punch through the water looks AMAZING!

 

Greetings Tethys!
You need open the shader "WaterPC.shader" and change line
GrabPass {
"_GrabTexture"
Tags { "LightMode" = "Always" "IgnoreProjector"="True" }
}

to"GrabPass { }"

Also, you can try to change line "Queue"="Transparent+1"
to "Queue"="Transparent+2" or on ""Queue"="Transparent-1". Underwater shader should have other rendering queue.

 

Thanks kripto! I tried both suggestions but neither one fixed the hole in the water visual effect nor the water drawing in front of my tree billboards.

 

Can you do the test scene for me? Also, go to skype "scar289", if you want.

 

Your included demo scenes work fine, this is just an issue with our particular setup. I just thought maybe I would probe you to see if you had any ideas why this drawing/sorting/depth issue is happening. I just added you on Skype, will catch up wiith you in a little bit, thanks again!

 

Hey, as an early buyer i was extremely surprised when i saw v2 and tried it and it really is something - give your thread a bump and a new title when you do a big update!

Main interest was the new river example it was excellent, soneone mentioned a flowmap control and i might add to this a wish for a control texture to control wave size over an area, and im assuming we can use our own meshes for the water (can shape it properly and uv properly for control textures)? I have no idea how much you are willing to implement what i suggested but i think a few people on the forum might be crossing their fingers

 

Hello,
In the next update I will try to add support for "flow map" and "waves map".
Maybe I'll try to add the oceanic water (huge waves, ssr translucent, etc.).
But it will not soon.

 

I am also having an issue where if I have Global Fog for me environment, either turned on in the Lighting tab or using the image effect on my camera, when I drop this water asset in my scene it blows out the scene to have fog everywhere and all my leaves and some of my bushes are all blown out to be the color of the fog. If I turn the water off it fixes it, or if I remove the fog from the scene it fixes. I would like to be able to use this water with the Unity Global Fog... is this not possible?

I also compared your shader code to the Unity water shader code, which does not have that bad visual/depth bug where it shows water below the surface as being on top of the surface, but have not been able to fix your shader to work like Unity's water shader in regards to ignore water below the water. I fixed your water shader pooping in front of other developers tree billboard shaders by removing +1 or -1 from Transparent and simply leaving it as "Transparent". If you have any other ideas about the render issue I am all ears - tried to add you on Skype but I am not seeing you still. Since this is for a live project on Steam I am putting your water on the shelf until we can fix it and will go back to using Unity's Water4Advanced for now.

 

I do not quite understand what you mean. Can i have screenshot with fog problem?
Standard fog "lighting tab-> fog" works properly with water. Perhaps some problems with the "underwater post-effect"? Try to deactivate "UnderwaterPosteffect.cs" in the water prefab.

Standard "Global Fog" post-effect does not work with transparent objects. (which queue 2500+).
Even the standard water not worked.
You can try change queue of water like that:

Code (CSharp):

1.  
2. _WaveScale ("Waves Scale", Float) = 1
3. _TexturesScale ("Textures Scale", Float) = 1
4. }
5.  
6. SubShader {
7.  
8. GrabPass { "_GrabTexture" }
9. Tags {"Queue" = "Transparent-500" "IgnoreProjector" = "True" "RenderType" = "Transparent"}
10. Cull Off
11. ZWrite Off
12.  
13. Pass {
14.  
15. CGPROGRAM

You can use "Tags {"Queue" = "Transparent" "IgnoreProjector" = "True" "RenderType" = "Transparent"}" it it work correclly.
Transparent+1 i'm use for unified grabpass optimisation. So, you can remove "_GrabTexture" and use just "transparent". Like that:

Code (CSharp):

1.  
2. GrabPass {  }
3. Tags {"Queue" = "Transparent" "IgnoreProjector" = "True" "RenderType" = "Transparent"}
4.  

Also, try to send me message in the skype again. Skype have some problems with network.

 

Hi,

water Looks really great! i there any hope that water depth/transparent water and/or foam is supported for the latest generation of mobile devices (ipad air/Iphone 6/s6 etc.)?

 

Hello,
Alas, i not have ios devices and can't test it.

 

Using the latest version of Unity (5.2), when I import this I get the error in the first picture. I imported the package again, and now I get the errors in the second picture.

 

Hello,
It's standart unity post-effect.
About first error. You have "sunshaft.cs/js" copy in other folders? Use only one script.
About second error. Just after import, apply unity's script auto-changes.

 

Thanks for the reply. I did those things, and now I get this error.

 

Now you have remove some file associated with the sunshaft. This file is "SunShafts.js"?
If you have problems with standart posteffect, you can change code in the script "UnderwaterPosEffect.cs"

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class UnderwaterPostEffects : MonoBehaviour
5. {
6.  
7.     public Color FogColor = new Color(87f/255f, 190f/255f, 219f/255f, 1);
8.     public float FogDensity = 0.05f;
9.  
10.     private Camera cam;
11.  
12.     void OnEnable()
13.     {
14. cam = Camera.main;
15.         var underwater = cam.gameObject.AddComponent<Underwater>();
16.         underwater.UnderwaterLevel = transform.position.y;
17.         underwater.FogColor = FogColor;
18.         underwater.FogDensity = FogDensity;
19.     }
20. }
21.  

 

Thanks for the help so far Kripto. It is looking great, but I am still getting errors.
1) I am getting the error in image Z3, no matter what camera object I link to, I have tried several.
2) When I look at my scene window, the water is correct, but when I run the scene, then the water plane seems to move to another place.

 

Ignore the second error, I have managed to fix that. Now it is only the error in image Z3 that I am struggling with.

 

Sorry, some bug
I've fix the code above.

 

Thanks, working great now. Looks fantastic!!! A really great product.

 

Hello Kripto,

How can I avoid the water rendering above my tree planes?

Regards
Carlos

 

Kripto,

I also found that the caustic doesn't cover the parts of the bottom underwater. How can I fix this? See picture, how the caustic is showing only on some square areas.

Regards,
Carlos

 

Hello,
If i understand correctly, you want optimize scene? Add for "reflectionCamera.cs" "far distance" for camera and use this, for exclude tree planes.

You use mobile caustic? Why caustic above the terrain on the screen?
If you use pc caustic, then just increase projector parameters. In the water prefab "Prefab->water->ripplesCaustic", change settings "orthographics size" and "far cleap plane".

 

Hello Kripto,

I use PC caustic since my game is for Xbox One. I don't understand what you are telling me to do when you say:
"Add for "reflectionCamera.cs" "far distance" for camera and use this, for exclude tree planes". Could you explain me better how to avoid the water rendering on top of my trees?

Regards,
Carlos

 

Do you want to remove the reflection of trees?
If you want to remove any reflection, then simply delete the script "reflectionCamera.cs".
If you want to ignore the reflection of trees then is not possible. Trees are in layer "Default". You can't ingore only trees.

 

No Kripto, he is having the same issue I have because transparent on the shader should not be Transparent+1, it needs to just be transparent so other developers tree planes LOD's properly render in front of your water shader(seems to be a depth issue). At least, that is what I found to be the fix - if you remove +1 and change it to just say Transparent after Queue instead of Transparent+1 tree billboards will render in front of water when they are supposed to. Hope that helps!

 

My english not very good. I misunderstood. Thanks you
ps It will be fixed in the next update.

 

My pleasure, you have been so great with support I could only return the favor.

 

Hello kripto and Tethys,

Thank you Tethys for the advice on removing the +1 on the shader. Unfortunately it didn't help. Now everything underwater, for example a wooden dock I have in the game, is totally visible as well as the end of the terrain plain that is underwater. Any other way to make the tree planes render before the water?

Regards,
Carlos

 

Hi guys - I just picked this asset up - but having an issue with flickering water when looking at it a certain way it seems.
Can see from here:

I have uSky and some other image effects on in the video but I've disabled them and tested and still have the same issue. Any idea what this might be?
