Strange lighting/shadows on cars

Hi there,

I just recently observed some strange looking lighting/shadows on the cars and wondered if that's normal or an issue. I tried it on the new Imola and Oulton Park. Day time was set to 15.30. I have all graphic settings maxed out except for anisotrophic filtering, which is set to 8.

The car bodies appear in a much brighter light than the lower section of the car, you would expect a smoother transition from bright to dark. Please take a look at the screenshots, I think they illustrate what I mean in a clearer way.

 

And there's some aliasing artifacts too at the border between the car body and the shadow.

 

Are you using a custom SweetFx preset ?
Maybe try disabling it or chaning to other one and see if still happens.

 

i think thats the alpha channel from the cockpit window.

 

Yes, I’m using a custom preset. I’ll try to use the normal preset next time and see what it looks like.

 

I just tried with default preset and without any preset, yet the issue still remains.
See screenshots attached. The cars look like cutouts, something is wrong with the transition from light/reflection to the shadows/bottom of the cars.

EDIT: Really seems to be an issue with cockpit view. If I switch to another view it's gone.

 

I think roby13 hit the nail on the head above

 

Ok. But what does that exactly mean?
I know Alpha channels from Photoshop, but what do they mean for the cockpit view?

 

the glass texture has alpha channel. gmotor2 cant handle multiple alpha channel layers

 

From the other cars on the pics i thought you were using just original content.
If you`re using a modded skin, especially the Windshield, then it`s definitily the issue.

 

No modded content, all vanilla.

 

Does it happen only with Marcas ?
On all Tracks with it ?

 

I never understood why using an alpha layer on the complete texture. On a part of it to imitate dirt is understandable

 

@Fabian Biehne have you tested different times of the day?
This could be related to shaders as well... sometimes different angles of lightning could cause a strange behaviour with the reflection.
