[RELEASED] Lux Water

it does not look as if there were any reflections.
just have a look at the water: it gets more and more black towards the horizon were usually reflections replace refraction (fresnel).
so put a chrome ball into your scene and check if it shows up any reflections from the skybox.

it is just geometry.

this scene uses a sliding volume.

so if you are using the water material from the ocean demo the brown tint may be simple caused by the color of the under water fog set in the material.

ocean demo: reflection intensity = 0.




ocean demo: reflection intensity = 1.

 

I am running this in deferred rendering with Enviro and NGSS 2 and just noticed that the objects below the surface is really visible when there is fog above the surface. I have not seen this before (just got the over-the-surface-fog working so it might be the reason why), is it normal?

 

i am not sure about this. but it might be related to ngss.
please let me know if it is not.

 

if not make sure that you have checked advanced deferred fog in the underwater rendering script and you have tweaked the shader to apply proper enviro fog. you also need the tweaked enviro fog shader which should be included in the enviro package already.

 

All settings is as it should be, I'll hope. Advanced deferred fog, DeferredFog.cs is updated and WaterSetup is set to Enviro. I made some tests, and I think it is the volumetric lighting in Enviro that is "leaking" below the water surface. Switching it on and of made some changes, nothing else did, with or without NGSS. I hope that it is some easy way of fixing it if thats the real problem.

While I'm here. Is this something that is expected, that the sun reflects in the water behind the terrain (as shown in the in the middle)? If so, can I disable the reflection when it is behind the terrain or something?

 

this is expected as transparent materials do not receive shadows by default.
you would have to sample the shadow cascades per pixel to support this – which is quite expensive tho.

i am not sure if i checked this, sorry. i do not use enviro. but the strategy should be the same as used by the fog: use the water mask provided by the under water rendering script when deferred fog is enabled to mask the volumetric lighting on parts which are below the water surface.
i may have a look into this tonight.

 

I have 0 experience with shader programming so this might be what you said, but in other words.

Enviro is using some sort of cookie created from the clouds that is used as fake shadows on the ground. Works fine with the water, even follows the waves. Would it be possible to do something like that, grab det depth map(?), the shadows in view of the frustum then apply it to the water.

EDIT: Super impressive with your fast response on the volumetric light! I was expecting it to get last in a big TODO list

 

if enviro adds a cookie to the directional light to simulate cloud shadows these sadows should effect specular highlights as well.
but as specular can have very crazy and high values you have to have real black in the cookie texture to actually kill specular highlights.

 

i had a look into enviro: its volumetric lighting is applied together with the fog.
so if the fog gets proeprly blocked the volumetric lighting will be too like shown on the following screen shot from the frame debugger:



i am not familiar with enviro's demo gui but having a closer look at your FIRST screen shot it looks as if volumetric lighting is disabled but light shafts are enabled?!

lux water does not handle enviros light shafts. so all you can do right now is playing around with the image effect order:
selct your camera and make sure that enviro's image effects are ABOVE the lux underwater rendering script.

i hope this helps.

 

@larsbertram1 Thanks for your fast support! But I think I've found the "problem". I played with some values on the water shader and found out that it might be the subsurface scattering. All settings is the same except the Occlusion and Intensity(Water).

 

yeah, subsurface scattering can reveal underwater geometry as well.
however i looked into the latest version of enviro and lux water and in fact volumetric lighting broken.
it seems to be way stronger now and has a similar effect as strong sss.

 

Hey,

Is it possible to use Planar Reflection script with occlusion culling? Right now the tree reflections etc disappear when they get culled.

 

i never tried this. you may try to add checkbox like: use occlusion culling and set up the reflection camera accordingly.

 

Hi @larsbertram1 !
LuxWater works with URP?

regards

 

it does not, sorry.

 

Looks great. Did you ever see if it's compatible with TrueSKY?

 

it supports enviro, azure and aura 2 ... sorry, if your sky solution is not in this list.
but did trysky ever make it into unity?
if so you may contact the developers and we might figure something out.

 

It use to be sold on the asset store, but now they're only offering it through their website.

Do you know if anyone has gotten your asset to work with OverCloud? I'm trying to find a volumetric cloud based solution to work with your asset.

Thanks.

 

have a look here:

I am working on a project and the whole scene is black with the exception of waves of green and white pixels.

 

I am using Lux Water any suggestion is greatly appreciated.

 

It's hard to tell why without more information. What version of Unity are you using? Try starting with a Lux demo scene, then save it as a new scene and delete what you don't need. Next add your other components one by one so that you can tell if there is a problem with one of them.

 

Can you share the above setup for Lux Water?

 

It is very old but here the link.
Assets:
- Lux Water (not included)
- MicroSplat (free asset)
- Dnk_Dev HQ Rock Pack Free (free asset )
- NaturalTilingTextures (free asset)
cheers

Thanks Max for the file...I am installing and let you know how it goes...

 

@larsbertram1 your asset is wonderful..
The only thing currently not working correctly is distance fog with aura 2. Do you already have a solution that allows aura 2 and lux water work together?

 

it should already work.
but i am not sure if the latest version ahs been added to aura 2 already...

 

When is the URP going to be supported?

 

no eta.

 

Dear LuxWater
It is posible use "Unity Recorder" and have the blur effect under the water?
Thanks!!
Andres

 

is it not?

 

Been playing around with your lovely water system and it does look wonderful, great job I have been trying to get it to change the sea state based on my own weather values, so I have wind speed and direction and based on those I am trying to change the Gerstner values to go from flat calm to largish waves and moving in the correct direction etc. But I am having an issue I need some help with.
I can't seem to change the Freq or Speed values without seeing a nasty jumps in the waves in the scene, is it possible to change these values smoothly?

 

unfortunately, no... gerstner waves have no memory. you would need to use a render texture to support this.
but you can change the final offset at least...

 

No worries I will work around it somehow. On another point is there a trick to getting fog working with Lux and Enviro, I have followed the instructions and uncommented Enviro fog in LUXWater_Setup.cginc and reimported the shaders but there is no change, not seeing any fog at all. If I change to Linear fog then all the water is totally fogged out. Am I missing something? Where does LUX Water get its fog settings from?

 

you have to cmment default fog and uncomment enviro fog,

 

Ok I commented out all the default fog but I am still not seeing any fog for some reason. Where does LUX water get its fog settings from?

 

Arr think its working now, though cant seem to get it very foggy at all.

 

the water? or all the scene? i am no enviro expert tho.

 

My water surface is cutting out. it is taking the shapes from above and cutting out water surface as seen in the bottom display1. Looks great in scene on top. But we see display with VR. Thanks for help !

 

looks as if the water shader flips or does not flip the depth texture...
which version of unity? which vr sdk?

 

It works smoothly on Android phones with unlimited ocean, and forward rendering.

But when I imported it to iOS and use Metal, at first, it is all good. Then at some point in time, the waves seems to stutter or skipping, and as the time goes on, it becomes worse.

Any idea how should I fix it?

 

Any word on when LUX will support URP?

 

i never heard of this so far... anybody here having the same problem?
(i only checked old metal 1 on desktop.)

 

nope. URP still changes too frequently and still lacks some functionality. i was told that some will be added to 2020. but that is nothing i am looking into right now.

 

here's a video of the problem:

 

still: i can not reproduce it.

 

Hi,
I am trying to implement water splash visual effect by placing a screen in front of the camera, and applying a material with Unity GlassStainedBumpDistort shader to it.
However on some angles (this depends only on camera angle) the water is not rendered at all.
Any ideas on how I should edit the GlassStainedBumpDistort shader, to remove this visual bug?
Thank you.

 

have you tried it on an iOS device?

 

here's an error from the XCode that might help:

 

make sure that your distortion plane always renders after the water by raising its render queue. so try setting it to 3010 e.g.
