Effect of the sun -- you mean cockpit self shading?

Great! Thanks a lot!

can you add in options menu the limited bombs option separate from the limited ammo option?

Thanks! That's quick service!

Or, if you want to make things a bit more complex, three options for limited ammo:

Limited ammo
Limited rockets
Limited bombs/torpedoes

Also, an option to turn off unlimited ammo during a mission would be welcome. That way players could practice bombing, torpedo and rocket attacks as much as they want until enemy planes show up or their plane takes damage, then jettison stores in order to dogfight or flee.

Admittedly, about as realistic as breast implants, but fun!

Or possibly sun glare. I've noticed that sometimes sun glare effects persist in external view when the game is paused, even when you pivot so you're not facing the sun. Not only is it somewhat unrealistic, it also messes up screen shots.

Lens flare effects can be turned off in the conf.ini.

My english is not good
I referred to this effect

Yes! Shadows in the cockpit.
No, unfortunately seems that the old IL2 game engine does not suport this. But Mr. Avala has proposed something called "cockpit shining" in which the cockpit gets brighter or darker depending on the angle of incidence of light. Good effect! Better than nothing. Don't know about the current status of this work, assuming it was not canceled...

That is called "self shadowing". It's actually fairly complex as I've been told to do that unless the 3D engine was designed for it from the start.
