SAM smoke trails

[WildBillKelsoe]

I think needs to persist more than 10 seconds to spot the shooter after maneuvers. Agreed?

Checked some youtube video. That no scientific - this is time for a smoke to mostly dissapear - mesured at a specific point of the smoke trail

 

 

Avenger : 6s

Chaparral : 1s

Hawk : 15s min, saw some going to 25-30s

Patriot : up to 30s

.....S300 : 0s http://www.youtube.com/watch?v=Fv_0hNRtaWA

 

 

In DCS - Hawk is 4s

Even so, we need smoke to persist for like 20 seconds for all missiles, specially in multiplayer.

I once heard from discovery that modern missiles use smokeless engines.

Yes i suppose this is true for missiles such as the AIM-120 but for older types like the AIM-7 or R-27 the smoke should really linger a bit longer before dissipating.

 

I'll take a deep look around the files in DCS this evening to see if theres anything that controls these effects.

 

edit: i doubt that this is editable, since many of these effects are newer particle effects that may be hardcoded, i'll keep looking anyways (and asking)

They do, however at altitude missiles will produce contrails while their motors are burning, just like jet engines.

 

So even smokeless motors can leave a trail in the right conditions.

Spent sometime looking into this but haven't found anything useful. It seems to have some nice files in bazar/effect and bazar/particle, but haven't found yet anything relevant to missiles.

Please note i'm a rookie and most chances are that i have missed something.

[NineLine]

As a side note, would them being hard-coded make more sense as far as an anti-cheat measure?

I agree, SAM smoke needs to stay around more than what it does ingame now.

 

Another example if anyone is curious to see:

[Speed]

Be careful what you wish for. They might need to improve/optimize their contrail/smoke trail effects first... last I looked, if I turned my head towards a bunch of contrails, it turned my game into DCS: PowerPoint.

 

But I'm not big into graphics- so I haven't checked in a long time. Anyone know how the current smoke/contrail effects are on frame rates? Are they any better?

[WildBillKelsoe]

Ok, somebody please direct our query to the right department, so we can SPOT the shooter. AAM are also in need of some tweaking

Oh, I use smokeless baccy, a.k.a. DIP

I posted this other day in the wishlist.

 

Falcon 4 BMS I think has got it right. A lot better visibility of the SAM smoke trails.

 

ED can you please make changes to the smoke modelling? Check out ralfi's F4 BMS video.... for the SA-3 site missile launch at 6:15.

Notice the persistent smoke. The smoke in DCS right now is just too light. Hard to even track it. In most RL videos I have seen...the smoke is persistent for a while and remains there and very dense. I guess also depends on air conditions...wind etc.

This is intended to be a simulator.

Could you possibly imagine the server overload with smoke trails made by your suggestion?

I don't really know what is realistic here, but let's not go with "so we can do THIS and THAT more easier" philosophy (from the first post).

Make it as realistic possible. Not as easier possible. Or it will fail (DCS idea).

Also, take note of the fact that smoke trails are affected by weather conditions (wind, air pressure etc). For some serious modeling of smoke trails - we will have to wait.

We got a dynamic weather engine - that is half-work done. Now "just" to code the behaviour of smoke to act acordingly to that.

So - a lot of research in meteorology and we all get realistic smoke trails :D

I'll say again, Falcon AF smoke from launcher is prominent, persistent, and we're talking about realism.

There is no doubt that big missiles like the patriot or the S300 leave huge smoke trails.I think

the should leave much bigger smoke trails in DCS for missiles like this, but not so much for small missiles.

I believe it doesen't really depend on the size of the missile but rather the fuel and propulsion method. OFC a larger missile will leave a bigger smoke trail then a smaller one with the same fuel type.

Well yes,I was doing a simplification . As you say bigger missiles usually have bigger engines that produces lots of smoke. Whatever be the reason we agree in the consequences ;).

Agree, longer duration needed!
