I remember seeing somewhere,that the shadows aren't rendered in the mirrors for performance reasons.

[Reinhard]

Yes. This a "feature". And I always hoped it will turn into an "option".

Hmm.
I see 'fake' shadows of the trailer and drive axles of my truck, in the mirrors. Not from the sun, but the same types of shadows you see when the truck is in the repair shop and so forth.
Concerning the cab casting shadows in the side mirrors: Could it be because the side mirror is actually reflecting something that is behind the cab, so it wouldn't appear anyway?

About the trailers..
When we pull up at the traffic lights behind a trailer that has a shiny reflective back 'surface' and a vehicle pulls up behind us, we only see the reflection of the vehicle behind us. Not our truck.
This is also evident in shiny surfaces on air-cleaners. Vehicles that are beside us appear in the reflection, but not the front end of the trailer, or any part of the truck.
Not seeing trailer shadows cast by the sun could be involved in that same cause?
Some AI that have come up behind me and merged into my lane too soon is almost as if they don't 'see' the trailer either.

Is all of this a game code thing and not simply non-rendering of shadows 'due to performance'?

[Reinhard]

It is for sure related to performance. For each mirror which is in (or near) your view, a complete different camera view of the world is rendered. So mirrors have massive impact, and this is why the drawing distance is usually very limited. But here, the user has some control. How far this can be set I never checked.

The engine simply cuts all 3D based shadow rendering from the mirror view. For every vehicle, regardless if it is the own, or the AI. The fake shadow is much "lighter", in terms of workload.

I didn't understand the remark concerning "cab casting shadows in the side mirrors". I never saw such an effect. May be related to graphic settings? Or is ATS different? "Air cleaners" makes me think you are talking about that.

I don't use full reflection, so I can't comment anything related.

Well, in one of the images posted by the OP, it shows a view looking out of the driver's seat and we see a cabin shadoiw cast on the road, but not in the mirror.

[xXCARL1992Xx]

you see the shadow with the player camera, mirror cameras omits them completely for performance reasons

[Reinhard]

Understand. As it is like that for every vehicle in the game, I didn't expected that to be a surprise, for the cab.

[room217au]

Exactly. I was implying that particular case was not performance as more 'angles of view'.
I've been wrong before and I'll be wrong again. It's my superpower.

I know this is old topic but it will be good if they fix this at least for tunnels because it makes no sense to see sunny road in the reflections of the mirrors when it should be shadowed. I passed like 4 tunnels earlier and it was shadowed only in one which is very weird. One more thing i tested with the F2 mirrors and their reflection was different compared to the truck one and light was correct on them. Not sure how it is for the newer trucks that has cameras.
