Doesn't work with fog

You can see the Terrain and the tree on the left completely ignore unity fog.

Hello,

shaders for unity terrain are a pain in the ass, to be honest.

I can check the fog issue if it does happen for normal meshes as well (probably does) - and if it affects any mesh and not just terrain, I'll fix it.

[swidku]

Yeah, it doesn't work on normal meshes too. You can see that poly tree on the left of my image using your shader completely ignoring the fog. To be honest I think the fog think is a global thing you'll need to implement to the shader and it would work on all objects including the terrain. I tried implementing it myself but I am terrible with shaders.

I was looking at this http://answers.unity3d.com/answers/1068485/view.html

Try it now, should work correctly even with multiple lights. :)

I'm sorry I completly missed implementing the standard fog when doing this shader, probably because where I used the app, I used a post-process fog effect.

If you find any more bugs, please report them. I suspect there is something wrong with the specular higlight sometimes (they seemed kinda off), but I'm not completly sure; so if you find a reproducible case, just tell me about it. :)

Yep works perfectly. Thanks for the super quick help.

I 'think' I might have found and issue with specular highlights: http://i.imgur.com/IaRVeON.gifv. In the GIF I'm changing the angle of the sun to simulate time changing, to provide a pseudo day/night cycle. The flickering is obviously not desired. If this is what you are looking for I could give you a copy of the terrain.

However, the flickering isn't really a big issue, it just shows that I should reduce the resolution of the terrain mesh. The bigger issue I'm having, and why I'm posting here is that as noted the shader doesn't support terrain fog as shown:

Switching to a the default shader fixes the fog.

I'll try to reproduce it with the terrain and let you know. :)

Can you give more specific description of the setup, or even better, send me a small reproduction project to [email protected]?

So I managed to get fog working with help from this link.

There's a a popping issue in the distance I need to fix, but once that's done I'll fork and submit a pull request
