TOZ Water Shaders

[aubergine]

Readme file:

v5.0
Rewritten all shaders and changed how things work.

IMPORTANT NOTE BEFORE YOU DO ANYTHING
Move the folders “Editor”, “Editor Default Resources”, “Plugins” to your root folder,
if you want to use the painting tools.

SHADERS:
There are 3 main groups of shaders now.
Basic, Medium and Pro

Also there are 3 types of shaders;
Base, Flow and Waves with additional specular versions.
Base is just water color.
Flow uses a flowmap to visualise river flowing.
Waves moves vertices up and down to give ocean visuals.

Basic:
These are very simple shaders for mobile use or cartoonish styles.
They get a main texture for visuals and a normal map for distortions.
There are also transparent versions if needed, transparency is got from the Color alpha.
Check the Demo_Basic scene for an example use.
(No script required except WaterFlow.cs if you use the flow versions)

Medium:
These shaders are medium quality, suitable for both mobile and PC applications.
These have correct and realistic fresnel calculations, slightly math heavy.
Medium shaders use a cubemap for reflections, and a texture for refractions.
This refraction texture can be anything that resembles the bottom of the water.
Check the Demo_Medium scene for an example use.
(WaterFlow.cs is required for flow versions, WaterSpecular.cs is required for specular versions)

Pro:
These are the most sophisticated shaders, and has 2 versions: Medium and Super
Super also has a sub category as SoftEdges
All these shaders are double sided, meaning you can go underwater.
They all target SM2.0, so can be used on mobile, but expect low fps.

Pro-Medium:
Uses Cubemap for reflections and realtime refractions.
Requires RenderRefraction.cs
(Additionally WaterSpecular.cs if specular version, WaterFlow.cs for flow version, WaterFog.cs if underwater)

Pro-Super:
Uses realtime reflections and refractions.
Requires RenderRefraction.cs and RenderReflection.cs
(Additionally WaterSpecular.cs if specular version, WaterFlow.cs for flow version, WaterFog.cs if underwater)

Pro-Super-SoftEdges:
Smiliar to above, additionally uses a custom depthmap for shores.
Requires RenderRefraction.cs and RenderReflection.cs
(Additionally WaterSpecular.cs if specular version, WaterFlow.cs for flow version, WaterFog.cs if underwater)

All of these shaders require Unity Pro version.

PARAMETERS:
Most shaders have smiliar parameters as below
Wave Power: is used for distortions of reflection and refractions.
Wave Speed: is the speed of water movement.
Fresnel Bias: is multiplier for Fresnel Power, default 0.2 is a good value.
Fresnel Power: is the most important variable for all shaders, it determines
how clear your water is, clear water reflects less and refracts more.

TOOLS:
In your Window->TOZ->Tools menu, there is a Flow map painter and a depth map painter tool.
Using these tools are as simple as it gets.
Select your water mesh in scene, activate one of the tools and press on paint.
Adjust your parameters and brushes and start painting.
After you are finished, press Save Texture button.
And apply the newly created texture to appropriate slot of your chosen material.

If you are not happy with the provided flowmap tool, here is another good one:
FlowMap Painter – teckArtist

TERMS:
Flowmap:
Flowmap is a texture with each pixel representing a Vector3 which shows the flow direction.
Our shaders require a Vector2 direction and that is the RG channel of a suitable texture.

Depthmap:
Its a grayscale texture which the r channel is added to fresnel value (Sort of transparency)

IMPORTANT NOTE:
IF you will use doublesided shaders, the underwater fog will only be activated
during playmode.
It is important that you set your above water fog parameters before going into play mode,
so the script can save your parameters before changing underwater fog.
It is also important that your main camera be above water before going into play mode.

KNOWN ISSUES:
*Flow shaders will only be visible after you play the scene once in editor.
*Flow shaders will result oddly if the player window loses focus.
These above issues are by design and not actually flaws.

Support:
These are generic shaders for overall use, if you need something customized,
feel free to contact me.
For any questions, you can contact me from aubergine2010@gmail.com.

Thanks for buying the package.

Hi, I’ve got the Unity 4 shaders so maybe this isn’t the correct thread. But I’ve applied the Pro/Super/SoftEdges/FlowSpec shader to a 3d cylinder that is animated and deformed moving through a pipe. The shader looks great except I am having clipping problems. There is a free camera in the scene and as the camera changes viewing angles you can see through geometry that is meant to appear solid. Do you have any suggestions? Thanks

I answered you in the 4.x forum post.

I’d be really interested in this. A couple of questions though:-

• how long before the webdemo is up and running?
• will you be creating some sample projects?
• will there be a manual/documentation?
• will this asset be enough in itself to cover rivers, lakes and seas/ocean?
• will you be able to tinker with things like reflection, refraction, caustics, different colours at different heights, wave heights, directions of waves, direction of flow, tidal effects, foams, breaking waves, ripple light effects and distortion under water, colour of the water surface?
• how much of the above does it cover?
• compatible with different platforms?

Sorry for all the questions but the Asset Store doesn’t tell me very much yet.

*Webdemo is not a priority now, but i will make one smiliar to the video.
*Sample Scenes: There are 3 demo scenes in the pack.
*Documentation can be found in the 2nd post of this forum thread.
*This asset covers rivers and lakes perfectly, ocean is partially covered with waves.
*Reflection/Refraction, water colors, waves, direction of waves, direction of flow, tidal animation is all customizable through a property. I have removed the caustics and underwater distortion effects from this pack, they are still in the 4.x pack (Aubergines Water Shaders)
*Compatible with every platform.

Hope i could answer some of your questions. You can have a better idea by watching the tutorial video, as i tried to use every tool there.
One final word is; this pack is for generic use, it is impossible to cover all and every feature you require as everybody has different requirements. In order to solve this, i provide a custom shader with the additional or customised features you want(reasonable ones) to whoever bought the package.

NOTE: If you already own Aubergines Water Shaders pack, you will be able to upgrade to this one for a smaller fee as soon as Assetstore implements upgrade path feature.

[Duffer123_1]

Understood. Thanks Aubergine

[Duffer123_1]

Any chance of it being up for sale on the Asset Store for the same price? (or is that in the hands of Unity)?

Also, any plans to develop TOZ Water Shaders any further?

The package on toztas.com and Assetstore is the same version and updates are released at the same time. But it is not easy to arrange a discount on the assetstore.

I have been maintaining all my packages since 4-5 years, and i will keep doing it for the life span of Unity 5.x regularly as well. It is up to you to do requests on how the pack should be improved.

@aubergine
Understood - thanks for coming back to me.

Nice water! I have looked for a long time for a water that would allow me to do river flow. I have one request though, and not sure if this is possible. I am looking for one that does foam edges, similar to Water4. I like that I can change the texture and have algae or water plant textures replace the foam. Looks fabulous in a pond.

Any chance you would add foam to this or is that outside the parameters for a shader?

Thank you.

Sure its possible, but im not going to add it to the pack though. It would require just a new set of 7 more shaders and i dont want to crowd the pack with more shaders.

However, all customers are entitled for a free custom shader. So, which specific shader do you want it to be added?
You also have 2 options;
1- can have foam like water4 using “depth intersection” which unnecessarily uses depth buffer.
2- can have foam with custom depth texture (the depth texture painting tool in the pack can be used to paint foam areas)

Contact me through the e-mail supplied in the readme file with your desired shader details as well as your invoice number please.

[Teila]

Wow, I did not expect this! I haven’t even purchased the asset yet. Give me a few days and I will get back to you with what we need. I need to consult with people who know more about this stuff than me…my programmers.

Thanks.

Hi,

you don’t really convincing me with the video. We need a video to see what is maximal (AAA+) possible with this asset firstly and not a tutorial (but the tutorial itself is good as tutorial). The water at all doesn’t look good. The overwhelming reflection destroys all the water feeling and the water also needs scattered lights. As mentioned, foam is important. Good things are e.g. the flow editor and the existence of under water. Another missing thing is i guess the deep water color and i also missed the shadow on the water surface. Waves would be also nice to have.
I did not bought this asset, i just missed this in the video, and i guess that these features aren’t available yet.

Anyway, do you support linear color space?

The video is not for convincing one person. This is a generic pack which adresses most common features necessary.
Further more, all shaders in this pack get its final color from the environment, so whether it looks beautiful or not depends on your artistic skills.
For the deep water color, shadows and waves, you should watch the video again with more attention.
If you are still not happy with what you see and want something specific, you can always hire me for your custom AAAA+150*500 needs.

Yes it works in both linear and gamma spaces.

Does it work with Planetary Terrain ?
In other words, will this shader work on a 100km radius sphere ?

[Teila]

I have to admit, I would like to see a webplayer demo. I have spent so much money on water solutions that do not work that I am very hesitant to buy something that promises something great only to find out that really it doesn’t. This is not an inexpensive asset and a demo should be offered before purchase.

I skip a lot of nice assets due to no demo so this is nothing personal.

@kzaurckichz

Not out of the box, but if you check the planetary terrain forum, i prepared some custom shader that does reflections/refractions on a spherical terrain.
Though it is not in this pack, i sell it seperately as a custom job.

I understand your concern and you are right, but i dont have much time to prepare a nice demo yet. We have some upcoming holidays, maybe i will do something by then which will not be very different than the video though.

The difference is with a demo, we can get in and “almost” touch the product. It would be nice to allow us to change the light from light to dark, as that is an issue for most water, and change a few parameters to make the water look different.

Right now, the one thing stopping me from buying Suimono is the fact that it hasn’t worked well with image effects and it eats up fps. Water4 never really gets dark at night, making it look out of place in realtime lighting. Those are important factors for me.
