Unity fog looks like static

Target Platforms Desktop

Hi,

I’m putting together a scene and adding fog to it. On my desktop, the fog looks fine, but on my laptop (Lenovo U410), it’s full of static. For example:

I’m assuming this is a driver issue? I’ve installed the latest drivers, or so I thought, but the problem persists…

Did you solve the problem?

I have the same issue.

Thank you.

Negative, it still persists. It only affects my laptop though, so I’ve taken to disabling fog there. Obviously, that’s not an optimal solution…

Do you have the same laptop and/or GPU?

In any case, i dare bet it’s due to the graphics chip the OP has. What type of fog and rendering path are you using?

EDIT: OP has a GT 610m in the laptop. this should not be seen as a real GPU (in terms of support of functions), more-like a video-acceleration chip. just like the Intel GMA’s, it’s simply not intended for 3d graphics and thus will not have a strong compatibility with certain functions which would basically be used only in games.

Looking for an actual graphics chip? dedicated GPU’s start for NVIDIA at x50-series usually, but whenever possible jump in at least at the x60-point. (In reference: I also own a mini-itx board which has a 520 which doesn’t support some functions, however those are all ran perfectly fine by an old 450 i have lieing around.

General advice (regarding compatibility and even performance); don’t develop with Nvidia sub-x40 or ANY Intel-GMA.
Will save tons of headache up front :wink: i’ve also resorted to sticking strictly to coding and texture generation whenever im on the box with the 520 :stuck_out_tongue:

A good first step would be to upgrade your graphics drivers and directX and see if that sorts your problem out. If not, it just might be that your laptop doesn’t have the hardware required to fully support the fog.

I have a Intel’s HD 4000 “GPU” (i7-3770). It is compatible with DX11 and full Shaders 5.0.

Thank you.

Must be overheating or bad drivers. See if you can check both. Failing that, you could try just adding a small vertex shader to each shader to simulate fog. But the gpu is compatible with fog because I have that gpu in my mac mini.

All games run good, and the temps are correct (35-40ºC).

As i said, I install recently the Intel’s last drivers, but I tested with other versions.

Thanks.

a gt610 or gt610m? there’s still quite a difference so wanted to check for sureness.

One thing: Only happens when I run Unity in DirectX 11 mode.

Any idea?

Perhaps you guys should report this as a bug.
