Fog not working ?

Hello,

It seems colored fog still not work even in the final version. The fog color don't appears, even with a high density.

Here's a shot of my fog settings :


I've tried in both deferred and forward paths.

 

No one having this problem ? Any solutions ?

 

screenshot?

 

Here's a comparison from an old build. Still having the same problem in every level, even with the final Unity for PSM.

 

Um, I'm clearly blind because, aside from some colour differences between the Vita screen and your PC screen I can't see any issue here. Remember that the Vita screen is a much lower resolution than your PC one so some effects will look different on the actual Vita hardware. I have to be honest and say that this is all I am seeing in those screenshots.

 

I can see the difference between the two, because I'm having the same problem myself. I'm using the same fog settings (with a density of 0.2 and black as the colour) and on the PSM Build there is no fog at all.

The following image is running on PC:


and on the Vita:


All the materials in the scene are using the Unlit/Texture shader.

 

@PeterD: I assure you there is a difference, maybe not visible in this comparison, but very visible on other cases.

@PadTheMad: Yes this is the same problem. BTW, I'm using the default diffuse shader, so this is not a shader problem it seems.

 

Yes I too can confirm that Fog is not working with the current shaders.

 

I have the same problem:
fog works on PC, Mac, Linux, Android
fog doesn't work on Vita

I'm not using special fog or texture settings

 

Can you put up a list (doesn't have to be complete) of which shaders to use if you want fog and also the snippet code that we need to patch into the existing shaders. Presumably it's the same for all non fixed function shaders.

 

Any chance someone could take the current diffuse shader and apply this patch, then share the result ? I'm a total noob at shaders (in Unity) so I can't do it myself. Thanks in advance

 

Thanks that is exactly what I needed.

 

Do you plan to add this automatic patching in an upcoming update ?
By the way, do you plan to update Unity for PSM 4.3 or do we need to wait for Unity 5 for the PSM bug fixes ?

 

I'd like to see this in the official build.

 

Hi, and thanks for today's hotfix update.

Unfortunately, fog is still not fixed in this update. Can you please share your plans on this ? (do we need to wait for 4.3 hotfix2, or Unity 5 ?). Fog is the only lacking feature that I'm looking for for my game.

 

I do think it is a critical bug, for these two reasons :
- You have to patch every shader in the game, and this mess up the others platform builds as the standard fog effect is still applied (the 2 fogs are active at the same time), a lot of time lost by switching the shaders.

- I've tried the patched diffuse shader on the Vita, with a red fog, the effect is visible, but with a black fog, I don't see any effect, or the result is not as expected, here's a comparison shot between the same scene on the Vita (with the patch) and on PC (without the patch), with a black fog applied. (consider only the center pillar, the other parts have black textures).

 

OK, thanks for the information. I hope you guys will find a solution for this feature somehow

 

Yes me too cause that's is what my game's lacking, its hard to make a zombie/horror fps without fog haha, that's all im waiting for, it's critical also

 

Ok I don't know how to make the fog to appear in the air but on items I just figured it out, use legacy diffused fast shaders

 

I've tried the legacy diffuse fast shader, but I have a strange problem, the model appears without textures, with a white / pink color, this happen also using other shaders such as vertex lit ect. (maybe fixed fonction shaders ?). I'm running in forward rendering. Any idea ?

 

Are you talking about the generic Unity's Log that you access from the console's top right? I did not find anything related to shader compilation error.

Anyway, I've been testing a few things, and found that linear fog doesn't work if it have a black color, in every platform (even in the editor), that's why I did not see a difference using your Windows Phone fog patch (which was a linear fog I suppose).

Then I've found this link, and tried the exponential fog patch, and now my black fog appears on Vita, still need to patch every shader in my game, but better than nothing...

 

Yea its better than nothing that's what imma do, I need to release my game asap...people always wanted a zombie game for the vita and a lot of people are asking for the release date

 

ok I tried that link and guess what, it still doesn't work... I NEED FOGG

 

Anyone having an issue with a shader or with fog on a specific shader, please start a new thread, post what you need the shader to do, and the code for the current shader you're trying to use (if it's just a standard Unity one and if it's unmodified just post the name is fine) I'll be happy to patch the shader for you as I've done most of them for my game (they aren't the standard unity ones they are my own, but it was pretty easy once you know what to do) so it would only take me 10 mins to fix one for you. Please don't just PM me, as I'm sure the fixes will be to everyones benefit.

 

Can u not post it here?

 

What shader do you need fog for? Is it one of the built in ones? If not can you post the source.

Thanks,

Jon
