This time it's exhaust flame color. Last time it was about map size. I'd be curious to see how many folks asking for changes or complaining ever worked on a game. How many of those folks are ready to upgrade their rigs to get a decent FPS.

Seriously there is a diffrence between asking questions and demanding changes on an unfinished product. It's already good that those little things are in there. It could just be a non lighted reddish texture mapped in the exhaust and have it called an exhaust glow but there are lights actually lighting up the engine cowling and particles, that's good.

Anyway keep up the good work, thanks for the updates, they make my day.

BTW are you alpha or you're beta?

DUDE, Oleg specifically asked for input on the exhaust flames!

No-one has been whining that they're not good enough. The posts on flame colour have all been constructive and backed-up their opinions with something.

Clearly this is something that Oleg is still tweaking.

He's made it clear that the map SIZE is set and not open to debate, but I don't see anyone whining about that. Some of us would like to know, however, if the map objects are still open to revision. Also not whining just a query.

He also explained why blue exaust in most instances is incorrect yet most here want it to be blue?

Maby the refferance in books saying the colour is blue is because they saw the flames in an angle looking straight down the stacks so to speak (from an angle and from behind) , like oleg explained, flames are blue just at the beginning of the outlet and gets more yellow the longer the stacks are.

just guessing.

One question about the last topic :
Will the ground vehicule could be weathered like the planes (maybe in a futur part) or not ?

Great work also

[AdMan]

the light radiating from the flame is too yellow no matter what the color of the flame, too much saturation

[Richie]

Hawker Sea Furry?

[McHilt]

Seeing all the vids of merlins and DBs I'd say blueish like many before me.
The color of flames indicate temperature and as temperature increases flames turn more transparent (the hottest temperatures are nearly invisible as I remember from chemistry class) but hey, I'm not an expert at that
I think the flames should be more transparent (in case when you'd use blueish flames). They also should illuminate the fuselage just slightly... just my opinion as a draughtsman, from what I've seen in the vids posted.

Anyway, nice feature...

Edit: maybe winny is right about that, efficiency rather than temperature but still

I'm probably being a little pedantic, sorry

Temperature is related to efficiency of burning too, so it is linked to the flame colour, but as they are both effects and have the same cause I ignored it..

You could get yellower flames from an exhaust pipe that had a build up of soot inside or around the edges of the pipe, but this would eventually burn away.. maybe they start yellower because the pipes are dirty?

I know that when they were testing the Spitfire at Boscombe Downs for night flights it was recorded that the exhaust flames were blue.

[winny]

Flame colour has nothing to do with the angle you view it from or the length of the exhaust pipe, it is nothing to do with temperature either. It simply shows how efficiently the fuel is burning.

If the combustion is burning all the carbon you get blue flames and no smoke. If there's carbon coming out in the exhaust gases then you'll get yellow-er/smoky-er flame.

This is chemistry not opinion.

We have videos showing it, some have seen it and most have read it in the accounts from pilots and crew that flew.

The Halifax I and II had terrible trouble with their positions being given away by blue exhaust flame from the merlins. They tried to cover it with metal guards but they glowed red instead. Only when the hercules engines were fitted in the III was the problem resolved.

I would like to hear the argument and evidence as to why it should be red and yellow rather than blue.

It's about the startup effect and not the exhaust glow of running engines. Whether we'll see a blue glow at night, possibly even depending on engine settings as explained in some posts (probably overkill though), is a different issue. Fingers crossed

Anyway, nice details and I'm especially happy to see the subtle reflectivity on the plane skin again, which has been absenst in all screens since months.
