Water+ (for Unity Free and Mobile)

The "material properties" section of the readme file goes over all of the settings. What settings in particular are you having trouble with?

 

Specifically, the "DUDV(RG) Foam(B)" , "Depth(R), Foam (G), Transparency(B), Refr strength(A)", "AnisoDir(RGB), AnisoLookup(A)", and "Caustics animation" image maps. Can you give me any info on those? Thanks.

 

All of those maps are internal to Water+ and there's nothing else you need to do to make the system work. The DUDV-Foam and caustics animation maps are included in Water+ (the internal maps directory). The Depth-Foam-Transparency-Refr(water map) along with the aniso map are generated when you press the "bake water maps" button.
You don't need to worry about any of those maps, Water+ handles them automatically.

 

Except, that I don't have a terrain in my scene since it is generated at run time and I think the "bake water maps" button requires a terrain, so I am asking about how these maps work and how I can generate them for my dynamic scene. Thanks.

 

Oh, now I understand what you mean. Unfortunately it's not possible to bake water maps at real time (and even if it was possible it would be impractical because of long baking process). However for your particular case I would recommend using the shader that doesn't make use of the water maps - WaterPlus\Desktop\Lite shader.
Let me know whether or not this works for you.

 

No the WaterPlus\Desktop\Lite shader doesn't work for me as it seems to have no transparency.
I don't want to "bake" them at runtime, I just want to understand how those image maps work so I can create reasonable water maps, myself. I just want to know how each of the channels in each of the image maps are used by the shader.

 

If you're targeting desktop, then you don't have to use an aniso map - it's used primarily for optimized lighting on mobile devices.
As for the water map:
1) Depth (R) channel is used for creating variance in color of the water surface (to have an illusion of depth underneath). You can simply put some sort of a noise in this channel.
2) Foam (G) - places where you want to have foam on your water surface. Brighter color = more foam.
3) Transparency (B) - how opaque the water surface is. 0 = completely transparent; 1 = completely opaque.
4) Refr strength (A) - refractivity strength. 0 = no refractions at all; 1 = max refractivity;

I hope this answers your questions.

 

Yes, thank you, that is the info I was looking for. I really appreciate your help.

 

Is this package still using the "tiled sand texture" approach for refraction? Why not make a camera that faces downwards, takes in EVERYTHING in the scene, culls out anything above the water, then renders a refraction map? Sounds like a good tradeoff for realtime stuff.

There's also the option of implementing this myself in my own shader, but for those Water+ users, this method may prove really effective! Obviously, there's the problem of having major aliasing, but the fix for that would be to tile water planes, and have a refraction texture for each plane.

Just a thought that came to mind when I heard you use "sand texture" approach for "baked' refraction.

 

How to do depth mask on it? Plz help me with it...I tried Unity wiki's depth mask but its not quite working as I needed

 

Hello, thanks for this excellent plugin. I can't seem to get it to run correctly on the iPhone or iPad, it causes a lot of memory issues, is there a guide on how to make the water use less memory or optimized for mobile ?

Thanks.

 

Hi! I bought your plugin and I would like to use it on a dynamically generated terrain. Is there an API to update foams on shorelines after a dynamic terrain has been generated? Thanks.

 

Hello, how can I enable cubemapping in unity editor? It's only working on mobile phones after building. But in editor there is no reflections on water.

 

Yeah, actually I even implemented this approach in an early version of Water+, but then decided to go with the tiled texture instead. Even when making the resolution of a "refraction map" 4096 it still looks extemely bad.

I have plans to make a version of Water+ for Unity Pro that will have real-time refractions and reflections.

 

Please follow instructions in the ReadMe file. The editor tool included automatically generates water maps, and puts a depth map into the red channel.

 

It should look the same in the editor. Are you sure that you have a cubemap assigned to the water surface material?

 

Everything is completely white in Unity 5.

 

Thanks !

 

@Saishy: check if the shader compiled properly; it looks like the shader half-compiled, then threw an error, causing it not to render properly.

On top of that, a "missing script" warning is in the console. Maybe something got broken on it's way to Unity 5?

 

Just a thought, @ilya_ca ,

if you solve problem on forum, the people who are facing similar problem will not need to email you again and you will not waste your time in repeating whole process to everyone with same problem.

So I guess you should solve problems on forum, it will benefit more

FYI, we opened up our project today and found the console was being spammed with mysterious XML errors. Took quite awhile to find out that Water+ was the culprit--apparently it was phoning home to check for updates, and the server was unavailable. So we wasted half the morning figuring this out. Very uncool.
