    Hi David,
    Thanks for your response. There is obviously something that I am not doing right, but I can't see what. I keep getting these artifacts in the scene, like siluette cutouts of plants etc or sometimes just blank cutout slits like in the previous post. What do you think might be causing this? I changed all sorts of settings, but without any luck:
    http://3d-art.co.uk/www.3d-art.co.uk/Artifacts.html

    What is curious is that the cutout image seems to be the same, although its a different part of the scene to the previous one I posted earlier. It almost looks like a ghost image of the imported vegetation. There seems to be some conflict related to the scene content perhaps. Its a mystery.

    Can you send me a build? I would like to see it in movement. It probably has something to do with your scene shaders. If they don't write to zbuffer, then we have a problem. Are you using alpha tested alpha or alpha blend?

    Hi David, I think I narrowed the problem down a bit more. It seems to be related to vegetation. I used a standard scene (Rocks and Boulder from K4) and then covered the area with your fog. The fog is left cut out by the swaying grass blades. I don't know whether this helps. Here is the screen grab for illustration: http://www.3d-art.co.uk/www.3d-art.co.uk/Artifacts_2.html

    Exactly. It has nothing to do with Fog but how the vegetation shader works. The Fog Volume will use Unity's depth buffer, and its built by scene shaders. Then your problem is related with your scene/vegetation shader.

    Thanks David, so all I need to do now is finding a way to fix it. Do you happen to have any suggestions where to look?

    I guess that vegetation is being animated in the vertex shader. I have never done that in Unity. But the thing is that the new vertex positions must be taken into account in order to update the depth buffer.

    By the way, you should contact the shader developer, this should be fixed because you will have the same problem with DOF and any other effect that reads from Depth texture.

    Just got this. Looks awesome! I'm using it on my whole scene to replace the built in unity fog (which looks much worse and messes up my ssao). Is there any way to exclude the sky from this fog volume? I could make the sky extra contrasty to offset what the fog volume does but that seems less than elegant.

    Ah, okay. Excluding the sky from fog is quite normal (is that what you were saying was weird?). The sky is excluded from both the camera global fog, and default fog in unity, so I thought perhaps there was a way.

    Yep, sounds weird for me :)
    Unity Fog is integrated inside every shader, that makes it more flexible for those kind of things. This is different, its a transparent shader like any other.

    btw, version 1.05 is uploaded and waiting for approval.


    • You can preview/experiment with the 3D Noise effect. Its ALPHA version.
    • It will only work if DX11 hardware is found.
    • In-scattering and noise are now set per fog volume. So no more conflicts when you have more than one fog volume.

    Hi - I am very impressed with your shader, and I'm hoping to use it for an underwater scene as the effect is amazing, especially with inscattering.

    I'm rendering in stereo (for VR) and I'm getting an artifact on the second camera:

    [​IMG]

    Basically it seems like it's using the depth/stencil from the first camera. I am confined to forward rendering.

    I would be very grateful for any help!

    Which color space are you using?

    I've been getting big visible step issues (like smoke sprites intersecting with the floor) in Linear, but its in both eyes.

    I was hoping the 3D noise would make it in - getting it working with candela could be a stress but ill figure it out - call it a buy from me when funds are assured

    Fog Volume 1.06 is out!

    [​IMG]


    1.06 Changes:

    • Effect won't dissapear in editor mode (deferred)
    • Volumetric Noise important improvements (Only DX11 for now)
    • Noise quality adjustment
    • Fog Volume is now connected with Foggy Lights 1.02. Foggy Lights will be affected by Fog Volume visibility
    • Inscattering is now inside Volume boundings
    • Fixed Noise intensity contrast

    IMPORTANT NOTE: THIS UPDATE WON'T WORK ON MOBILE
    ​(I hope I fix it soon)

    Hi David_MG,

    I bought your Fog Volume plugin earlier today for my project, and with a perspective camera the fogs works just fine. However, it simply does not work when using an orthographic camera, which my game uses, making the plugin useless for me. This isn't mentioned anywhere in the description or documentation. :-\

    Sorry for that, never tried that option. This would need a custom solution.

    Does this shader work with transparent shaders? I have Advanced Surface shaders and have been using the volumetric objects for fog. However, one problem besides the scattering not being present like in this asset is the fact that my fog is rendered awkwardly when it comes to things like leaves and other transparent objects.

    $fogbug.JPG

    Can this asset deal with that sort of thing? I'd definitely pick this up if it does.

    Snippet from documentation:

    Some people think this is my fault. It's NOT. This is how computer graphics works for now, and I can't do much to fix this problem.

    I have tried writing Depth. Its not the perfect solution, since what you need is to attenuate fog from background-to-object with object-to-camera fog.

    The correct way should be something like:

    TransparentSurfaceFog = length(BackgroundPixelPosition - TransparentSurfacePixelPosition) x length(SurfacePixelPosition - CameraPosition)

    So that's why it's almost impossible to do easily. You need 2 different pixel positions and depths.

    Just writing Depth will create fog from camera to surface, not from surface to background.

    Hi David,

    I just bought foggy lights and foggy volume to work in conjunction in my oculus project. They're pretty great, thank you for producing these. I am working in OSX however and neglected to pay attention to the directX11 requirement for the noise function to work which I was particularly attracted to. Do you have any info to share about when this functionality may be available on platforms other than Windows?

    thank you!

    Thank you Julian. We have to thank Robert Briscoe and Ryan Wiancko, since they requested these products ^^
    Have you tried them in Oculus? Do they work well?
    Can't tell you right now when volumetric noise will work in mac. A programmer friend of mine is trying to do that part. Let's see if we are lucky. I can tell you volumetric noise will never work on mobile, hehe.

    Cheers!

    David,

    Yes, apart from the absence of the noise function they're working as advertised and not adding significant draw time or artefacts. I'm doing anything too fancy or using transparent textures at the moment, just using them for what they seem to be best at, adding atmosphere a good glows around my lighting. That's really exciting that the noise function looks like it's working in OSX! Can't wait for a build. :D

    Here are some screenshots. I'm pretty new to Unity so it's only been a month. You can see how the noise function would be quite effective in this context... I didn't grab these in play mode as the lights function differently at runtime. But the fog volume and foggy lights look like this:

    Marvelous! Thank you. Can you please make it more exaggerated? I want to see if depth information is correct :)
    And, what do you mean with "I didn't grab these in play mode as the lights function differently at runtime"

    David,

    here's another screenshot. I've decreased the visibility parameter for the fog volume and lowered the exponent for the foggy lights. I wasn't sure how you wanted the exaggeration to occur. I figured you wanted to see the volume extents.

    I meant that my light setup flickers a lot [on purpose] at runtime, so getting a frame with the oculus CA and distortion was harder. So I just turned up values statically and grabbed the game window.

    Julian - that looks awesome.

    Are you using forward or deferred rendering in your project? Also did you have to change anything to get it working?
    The reason I ask is that I'm having problems getting the right camera to render properly (see Whale screenshot on last page) in forward rendering mode - which I have to use for my project.

    Hey sfaok,

    I'm using forward rendering. No I didn't have to change anything. I saw your screenshot but I don't have anything to suggest sorry, other than I have struggled with some of Unity's post effects like sunlight shafts and global fog in terms of oculus integration. That's why I turned to David's fog volume and foggy light tools. I presume Unity and oculus will resolve some of these issues as it's still early days for complete oculus integration at this point.

    I'm not super experienced with Unity so my only suggestions would be to check light count, transparent textures and draw priorities for your forward rendering stuff? Do you have post effects on your oculus cameras? Things can get messy there because oculus output from unity prefers to do distortion and chromatic aberration correction first and post effects want to come after. This won't work properly. Drash on the oculus forums posted and interesting solution here.

    good luck.

    Hey David. I'm having very strange artifacts when I have SSAO on my camera, and when Advanced Foliage Shader is on screen. This happened after one of the more recent fog volume updates (sorry to say I don't know which one). I don't know if you have the advanced foliage asset, but would you have any guesses as to what might be causing this? The artifact seems to look like my foliage texture sheet (so weird) and it goes away when there are no advanced foliage shader assets on screen.

    Yes, I noticed and fixed it yesterday. Hopefully that will be fixed in the next revision: 1.08, which is waiting for approval.

    Thanks! With your feedback it will progressively improve:)

    Just picked this up from the store. It's working great so far, but I noticed one bug: when duplicating a fog volume in the hierarchy, the fog loses its soft edges and shares a color with the duplicated volume. Creating multiple volumes by using GameObject -> Create Other -> Fog Volume works fine, but duplicating volumes in the scene does not.

    Also, I'm wondering if its possible to have a color gradient for fog volumes based on height and/or depth. I'm trying to get the effect working with multiple volumes but it isn't really working out.

    Hey Ryan, I was curious about what you were wanting to do with the bridge and the lights and tried it myself. Also the 1.07 version of fog volume appeared and also has the noise function working correctly on OSX. I managed to get the fog lights to NOT be eaten up by the fog volume as they recede by un-ticking the 'Inside Fog Volume' option for each fog light. Forgive me if you have already sorted this all out. Here's a screenshot of where I got to. [Note: I have not evaluated the framerate hit for this setup so YMMV of course]:

    Update: I'm using David's FogVolume AND FoggyLight in conjunction to achieve this look.

    Hey David - awesome work! FogVolume is amazing.

    I just wanted to mirror what others have noted in regards to Oculus integration. We're seeing a ghosted version of the right camera's fog volume on the left camera. In the screenshot we can see a ghost tree.

    [​IMG]

    Also, the rain shader we have disappears on the righthand camera in the fog, but works perfectly on the left. Not sure how to correct this, but it appears to be related to the fog volume working properly on the right camera. Any ideas?

    Happy to share a build of this scene if helpful! And thanks so much for creating this.

    Hi , ive purchased the file but im having trouble using it. It works fine as long as the camera is INSIDE the Fog object but once i move the cube the effect simply disappears . Also i cant see anything in the editor. except for the wireframe and the " FogVolume" icon in the middle . Please see the attached screen shot . Im using Unity 4.3 on Mac with the free license. ( iOS target project)

    Hey guys, I've been unavailable for some weeks. I will give you support about these issues as soon as possible. Thanks for your patience.

    I'm getting this choppiness. If I make the fog thicker it goes away, but I was going for a much more subtle fog.

    If I drop the color alphas all the way down I still see these choppy plane intersections. I thought it was an issue with the Rift or something at first, but it does it on regular camera setups as well.

    Also, is there any way to subtract a volume from the fog? For instance having a fog outside as one setup, then a volume for interiors, or no fog in some places.

    The plane intersections you mentioned are related with 3D Noise sampling. Its computed only inside the volume, that's why you see that dramatic seam. What you are seeing is the noise sampling edge. Volumetric effects have some drawbacks. Most of the time we have to deal with this kind of unwanted implications.

    In theory, subtraction is not impossible, but doesn't sound easy nor cheap atm.

    As described in the documentation, Fog Volume requires Unity Pro. Otherwise, it won't work.
