[RELEASE] Calm Water

Hey,
The bug is on the grabPass that's responsible for the distortion and the coloring of the underwater. It is a built-in unity command and there is no way to change it. One possible solution would be to use command buffers to generate the screen grab instead, but this would require a major and not trivial change of the asset.

 

Hello Yan,

I own your Calm water asset and I was looking at your stylized fog. Would that fog work together with your water asset in order to create a more convincing underwater fog. My plan would be to use your stylized fog gradient to create the fog closer to the surface lighter and further from the surface darker ( imitating light scattering effect).

I work in forward path.

Please let me know

Regards,
Carlos

 

Hi,
Unfortunately it won't work for two reasons, first StylizedFog limitation is that it works only on objects that writes to the depth buffer and CalmWater does not. Second reason is that the fog is more of a distance fog, you have no control on the height of the fog like the underwater fog from the asset.

 

Thank you Yan. I appreciate your help as always.

Regards,
Carlos

 

Hello Yan,

In the last version of your water the reflection is very very low resolution, how can I change the resolution of the reflection?

Hi,

I recently started using Calm Water and i think it's great! However i made a iOS build yesterday and noticed it does not behave as it does in the editor (See dropbox link). I'm using Unity 2017.2.0p4 and the single sided shader, iPhone 7 iOS 11.2.

Hey,
Normaly you should have a quality option on the mirror reflection script. This setting controls the resolution of the reflection texture. You can try setting it to a higher quality level to get better resolution.

 

Hey,
unfortunately I don't have an IOS device to test it out, but I can try to help you.

• What are your quality settings for IOS?
• Is there one directional light affecting the water on IOS or are your pixel lights disabled on this platform?
• Do you have the CameraDepthMode script added to your main camera?
• Is the scale of your water plane [1,1,1] ?
• Does your water plane have tangents and normals generated?

Also if you can provide me with a reproduction project including the relevant assets I will have a look!
thanks!

 

Yan,

I didn't have any quality options of my reflection script, but I created one for the size of the texture that is created in the script. The problem was that somehow I have to restart Unity everytime I change the texture size in order for the changes to take effect in the game view. But I already did so. Any ideas about what could be making this refleshing problem happen?

Regards,
Carlos

 

Hi,

• What are your quality settings for IOS?
• A: We use custom quality settings, the Pixel Light Count is set to 10
  
• Is there one directional light affecting the water on IOS or are your pixel lights disabled on this platform?
• A: We use one direction light for the water, no other real time lights.
  
• Do you have the CameraDepthMode script added to your main camera?
• A: Yes
  
• Is the scale of your water plane [1,1,1] ?
• A: We used the "Create water plan" tool to generate it and it has [1,1,1] scale.
  
• Does your water plane have tangents and normals generated?
• A: I guess?

I'll go ahead and try it in a empty project and if the problem exist there as well ill send it to you.

Thanks,
Kristofer

 

I should add that everything works fine on Android so it seems to be specific to iOS. As you can see in the video the water is not rendered when looking directly in opposite to the light direction.

Also i should mention that we use cubemaps for reflection.

 

hey,
if you contact me by email I will send you some debug shader for you to test so we can find what is wrong!

Thanks!

 

I sent you a DM with my email adress here on the forums.

Thanks!

 

hummm maybe the rendertexture doesn't get destroyed when you exit play mode and thus don't create a new one with the different resolution when you go back to play mode?

You probably don't have the latest version of the reflection script then, if you are on unity lower than 5.6 you probably don't have access to the update, I can send you the latest version of the reflection script in PV, it should work with older version of the shader too.

 

I work with Unity 2017 2.0p1, which is the latest stable for Xbox One. Could you please send me the latest version of the Reflection Script then? I had changed the script to not use occlusion culling by the camera, since the reflections disappear straight at front of the camera which is not pretty.

Hi there, I was interested in purchasing this asset, but am worried about single-pass compatibility. Has Unity fixed the bug related to single-pass rendering on their end?

 

They seem to have it fixed in 2018.1, but I have not tested it yet.
https://issuetracker.unity3d.com/is...nly-one-eye-with-single-pass-rendering-method

 

Thanks for the prompt reply. Would you be open to a refund if the asset doesn't perform in v2018.1? Or are all sales final?

 

of course refund is accepted if you are not satisfied.

 

Hi! I love the way your water looks and have it in my cart ready to buy, but I have a question before I checkout:

Does this support holes in the mesh? I have an island in my game, and there are several parts of the landmass that go underneath the water level, but I don't want them filled with water. Can I use a custom mesh that allows me to "cut out" those sections of the water plane?

 

Hi,
Yes you can use custom mesh no problem! Same if you want to create only a strip of mesh with straight uv to make it look like a small river and the water will follow the curve of the mesh when it turns, you can do it!

Just be sure to have normals and tangent in your mesh import settings and leave the scale of the mesh to(1,1,1) if you plan to use displacement.

Don't hesitate if you have any other questions!

 

Hello, I'm a newbie and also not good at English either.

As you can see the water disappears while the other effects active. How can I fix that?

Please...

 

Hi,
I'm not exactly sure what your effect is, particle system with shader that writes in z maybe?
This seems like a z-ordering issue with your effect. You will need to either change the rendering order on your effect's material or on the water's material so that the water has a lower render order than your effect.

 

Thank you very much, the problem is I can't find the render order in the water material, I scroll down to the bottom as usual but I cannot see it, where can I find those number?

 

Hi,
Right since it's a custom inspector it's not there by default, I will try to include this in the next update. For now you can just set the inspector in debug mode, there you will have access to the render queue.

this video shows how to set the inspector to debug mode in case you don't know

Thanks!

 

Hi. I've been using this pack for a while now for a VR project and it looks great. Do reflections work in VR yet or is that still an issue?

 

Hi,
realtime reflection is still an issue as it would be very expensive for VR, however if you really need it you could use realtime reflection, you could to a realtime cubemap with a technique like this one: http://twiik.net/articles/realtime-reflections-in-unity-5

I have been working on other features for the next release and still have other priorities before I do Realtime reflection for VR so don't wait too much for it.

Best regards

 

Ok thanks a lot for the response.

 

Hi,

The reflections look great. However, when I plug a cubemap into the Reflections, I seem to get these strange aliasing artifacts, like the normals are using point filtering. This is using the included water material and normals - the cubemap resolution is 1028, and looks fine when I reduce the normal strength. This is in deferred Unity 2017.

 

Hi!
I think it's the distortion in the reflection that is too strong and causing this. In the next release there is going to have a slider to control the amount of distortion that gets applied to the cubemap, but unfortunately there is no way of controlling that via the exposed parameters at the moment. If you need it now now, contact me in private I will show you how to reduce the amount of distortion by hand in the code.

Thanks!

 

Hi @Phantom_X -- great asset, thanks!

Just to let you know - I cannot access the docs site URL if I'm signed into any of my Google accounts, it gives me a weird permissions error. So I have to access via another web browser that's not signed in.

// WildStyle

 

Please send me a PM if possible - thanks!

 

Hi,
Thanks for the info!
I double checked and the sharing setting is set to "Anyone can find and view" so that's odd, but if you still can't access it, send me your email address in PV and I will manually add you the list to see if it helps.

 

HDRP?

 

Hey,
Only shader made with the shadergraph are going to work with the HDRP and LWRD, so no for the moment.

 

Hey, love the asset. I was wondering if you could add Single-Pass Instanced support to the shader? https://docs.unity3d.com/Manual/SinglePassInstancing.html

It would provide a huge performance boost for stereo rendering.

 

Hi!

Just to be clear, instancing is giving you performance boost only if you have hundreds of water planes in your scene. If you only have a couple the overhead given by the instancing is going to make it slower. So unless you have a map composed of hundreds of different water object it's not going to help.

What is your use case exactly?

 

Right, but Single Pass Instanced stereo rendering mode is different from just instancing materials. It cuts render thread time in half for all opaques / transparent objects and also helps with the user mode driver performance. All shaders being used in the scene have to support SP Instanced render mode in order for me to use it. Oculus calls it "multi-view" and recommends it over multi-pass and single-pass.

 

Haaa I see, I wasn't aware of this mode. I guess I can try to add it since it doesn't seems to be a big change at first glance.

 

Great, any idea what when you can push an update?

 

Will try more in depth this weekend and see how it goes

 

Hi - this asset looks great, does it work fully in VR?
Are there some underwater effects in VR?

Thank you

 

Hi,
Most of it work in VR, only the realtime reflection don't. There is some underwater effect, but to be honest I haven't touched the underwater effect in a while and I can't remember if it works with VR. I will be at GDC for the whole week so can't look into that right now, but will check when I come back!

 

Anyone else having the issue where the shader shows up in "In game view" but not "Scene view"? Does it has something to do with these warning here?

Thanks

 

I think that might be because you are in forward rendering and you did not add the cameradepthmode script on your main camera

 

Ok we are going to investigate this now, thanks for the quick response.

Any idea why?

Hey,
I think this might be caused by a lot of things, have a look at this thread and try to find if any of these situations apply to you. https://forum.unity.com/threads/solved-screen-position-out-of-view-frustum.60851/

 

Hi!
Any update on potential hdrp support? (last time the question was asked was over 6 months ago )

 

Hey,
HDRP is too different to just 'support it', most of the core functions of calm water is just not available in HDRP. If I make a water shader for HDRP it will probably be a separate asset to keep it clean.
