[RELEASED] Lux Water

Hi,
your asset is very great and the best for me, but i've just a problem with the particle, as you can see in my image we can't see the particule (white dot line) when you are above the waterplane, i've drawn in red dot where they should appear. have you an idea,or better a solution ?

 

if you want particles to be drawn on top of the water you have to render them at a higher render queue compared to the water e.g. 3001. please note: changing the render queue might break sorting of other transparent materials.

 

Hello @larsbertram1 ! I cant for some strange reason get the underwater effects work with spltscreen.. I have capsule collider and rigidbody on the player and the cam is a bit behind since is a thirdperson.. it changes the caustics and adds the ”barrier” and bubbles but no ”fog” like how it looks in the demo scene, I copied it ALL.. what have I missed?
Thanks

 

so underwater post is rendering (because you see caustics when the camera is underwater) but it does not add visible fog? try to increase the fog density along the view axis. that is all i can say right now.

 

I have same camera set, and copied the water from demo.. works there with the exact setup bit not in my own scene..

EDIT: Okay i got it to work now, seems not to work with standard assets third person controller ..So I just use a camera to test with sphere, trigger and rigidbody.. BUT: When I look up its black the water surface from beneath the water surface, I know I can change the underwater fog to like black then it looks good (but who wants it black) I want to change the black underwater water surface so it matches the fog or else it looks weird and the barriers show... I cant get it look blueish like in the splitscreen demo, where the fog is blueish and the water undersurface is blueish...?

 

do you know why? and this should effect the entire underwater post – not only fog.

the water surface from beneath is dominated by "total inner reflections". so if it is black your skybox (from which the global reflection probe is generated, see lighting tab) or the local reflection probe that gets picked up by the water is black at the bottom (enviro e.g. does this by default). so you have to "fix" the skybox or reflection probe.

 

For the record, only the non-optimised version works on my Mac setup. The issue is due to metal being unable to unroll loops of indeterminate length, I believe.

 

Thanks!

 

Im usng som HD skybox that comes with Gaia and it added some global reflection probe too... I have to check it out! Thanks!!
And I think the reason were with the standard controller that the maincamera was not a child of the character itself.. It had only a camera controller..

 

Hey all, i have a question, will lux water works with UniStorm?

 

i do not own unistorm. sp i do not know if it comes with its own custom fog?!
if not, it should be fine.

 

Hello! It still looks like this, even if I delete the probes and put the default skybox..?

 

that looks totally broken. even if reflections were black you should get some underwater fog on the backside.
no idea what is going on there.
have you checked the rendered water mask (you have to click/check gizmos in game view (upper right corner))?

 

No I dont think so, but I just generate lightning and suddenly it worked?! shouldnt have anything with that to do..

 

how does it look now?

 

Hello,
I really like your Lux Water asset, the underwater effect is really gorgeous. I do have a problem however, I can't quite understand how to use the underwater volume mesh when it is very large (my map is 13000x8000x13000). How to adapt it so that the underwater effect works everywhere with such constraints ?

 

the underwater volume has to be visible for the camera which means that it can't be bigger than the camera's far clipping plane.
so in case all your map is covered by water you will have to move the water mesh and volume with you camera.
make sure you move it in steps which fit the distance between the vertices of the water mesh to prevent water from popping.

 

ok so, do I have to create a mesh for the volume of water or I can use the ones of the demos scenes?

 

because my map is an ocean and I admit that I'm struggling to implement your asset despite the doc it's a shame because the rendering is perfect

 

you could use one from the demos – but actually i would recommend to create your own optimized version.

 

I didn't such information in the documentation, or maybe i missed it ? How can I create my own version ? Thank you by the way.

 

oh, there is a detailed explanation: https://docs.google.com/document/d/...m38h-u3Az-ozaaOX0/edit#heading=h.a35xd36psn27

 

yes I read it but with which software do you create the mesh? (I'm debutant on modeling)

 

me too
maya.

 

like in the demo scene but with my own coloring

 

When using this and AFS, which custom deferred shading library do I use?

 

in case you need deep water lighting?
you should take the afs deferred lighting shader and modify the "CalculateLight" function like in the LuxWater_DeferredShading.shader. make sure you include the "LuxWater_DeferredLibrary.cginc" and that it can be found by the afs deferred lighting shader – simply be copying it into the same folder.

 

Dear creator,

I just bought your assets, which your demo inspired me.
But I have tried importing it and played with the demo scene, and it failed at generating anything for volume based demo. All other simple ocean and river shader are working fine, except the volume and deep water, which totally render nothing and even surface of water is gone. Any help with this?

Thanks.

 

your console shows a lot og errors.
which version of unity are you on?
which platform is your target?
and which graphics api do you use?

 

Thanks for the attention!

Yes,the bug is only one single line, but looping in runtime.
(FYI, however the bug is not present in other volume scene demo file, it happened randomly sometimes not showing up. I did not take too much concern on them for the moment. )


I'm currently using Unity v.5.6.0f3 Personal.
I'm developing in Macbook Air, targeting for MacOS and Windows. ( But the build is in MacOS only currently ).

Graphics API, I unchecked the Auto to view the options, to find out which is Meta & OpenGLCore.

#UPDATE - I just checked your documentation once again, and figured out Metal has problem with Deferred rendering etc things, I am not too good at graphics API things for Unity, I will try to disable the Metal API and switch over to OpenGLCore for test to see what will happen.

 

#Update - I removed Metal graphics API, and tried with OpenGLCore, and Deferred Shading, still not showing anything

 

hmm, i have tested it in unity 5.6.3. on mac os 10.11.6. and both work well: metal and openglcore.
i started with a fresh import and openglcore: the LuxWater Water Volume Deep Water Demo just works – except from the missing light attenuation as i did not assign the deferred lighting shader.
then i switched to metal (by turning on metal editot support): water went away as expected.
i added the LuxWater_CameraDepthMode script to the camera a checked "grab depth texture".
i changed the water material from the tessellation version the the regular one then i edited the shader.

the result is almost ok metal does not handle point lights properly in the editor in 5.6.3.:

 

Hey @larsbertram1 .. So I added Enviro to my project, and now it looks again like the pic above, generate light didnt help... I saw in the manual that I have to edit the script, but isnt that only for fog above the water wich I will use volumetric fog for?
Thanks
Mattis

 

enviro seems to set the bottom of the reflection probe / skybox to black. there is a checkbox where you can turn that off.



regarding fog: i am not sure if the new enviro version is already available. if so you would have to edit the setup.cginc file to tell the shader that it shall call enviro's fog functions. you may ask in the enviro forum for further details.

 

Lars ~ I currently use TOD but i think its become legacy and i noticed lux is being supported by both Enviro and Azure sky systems for fog. In your personal opinion which of these sky systems works best with lux water? or is that a difficult question to answer?

 

i think there is no big difference.

i think water should not be ranked higher than your sky and weather system – unless you do a water centric game.

 

Thanks for the advice

 

you are welcome!

 

Give it any News about the dry mask future? I have a submarine and a underwater base, and the same Problem like the other customer here in that thread with the subnautica idea for the underwater submarine.

 

Ahhh thanks for the test!
It turned out actually I need to update the patch from the store, and then I should change the Deep Water demo's shader from [WaterSurfaceTessellation] to [WaterSurface], now it gave me a good simulation!

But is there any big difference in between tessellation and surface shader?
I am quite fine with the result of just [WaterSurface], since my game needs only lightweighted simulation of deep water exploration, so it will do so much, plus I really liked your simulation performance, which is 10x faster than my previous purchased one.

 

#Update - sorry it tested fine in my new imported project, but it failed as soon as I dragged in a volumetric lighting library HxVolumetric Light from assets store and my deep water is gone

The water surface is still present, but deep water just gone, no fogging.

I checked to make sure the Deferred lighting shader settings are okay, but no clue why it messed up
Could it be there any rendering orders problem?

 

you can only use one: either lux underwater rendering or hxvolumetric lighting as both do the "same": adding some kind of fog. hx of course adds "real" volumetrics including light shafts while the lux underwater rendering only mimics it.

 

Finally I almost managed to implement it for a very wide ocean. However the shader is removed after a certain depth despite the volume of water being correctly edited on maya (I imported one of your fbx volume and changed it directly). The box collider also takes all the depth. I have a small question too : I did not find how to change the density of the fog. How can I do it so that the player would see further under water ?

 

sorry, i do not understand what you are saying here. the shader is removed? do you mean the underwater rendering gets disabled at a certain depth? you should be able to check this by enabling debug.

you control it by changing its "- View Depth" (most common) and/or "- Depth Fade Start(X) Fade Range (Y) Density (Z)"

 

At a certain depth, the underwater rendering effect is disabled and the debug information shows I'm still considered inside the water volume.

 

you are inside the trigger collider, but are you inside the volume mesh as well?
if you click/activate "gizmos" in the game view window you should get a preview of the underwater mask. it should be more or less fully green.

 

Thanks creator, I will try to come back later as I need to hop onto some other modules at the moment, thanks for the tips, I will try to integrate soon and report back!

 

Is there an option for waterfall ?

 

Not seen one but you can use any spline/river tool to make the mesh then add the lux river material. After that it's probably a case of adding some particle effects to give the water spray/mist effect.

 

This plugin produces stunning looking water, I just wished it behaved like water, unless I am missing something it would be amazing if there was like an example of say a rubber duck floating on the surface? And if the river flowed so again the rubber duck would move down the river (on the surface) as you might expect water to behave.
