The jet engine contrails look disgusting at lower altitudes.


Recommended Posts

They look good when you're at high altitude, not so much when taking off or landing.

I get that you need something to indicate whether or not the engines are throttling up, and it might work for, say, RAPIERS and ramjets, but on the Wheesley and Juno?

No. Eugh. no. 

An alternative:
 

You know the exhaust at the other end of an airliner's engine? It's sort of a blur?

That might work, but less intense.

At high altitude, say, 5000m, the contrails could be displayed:

..That's it. Tell me what you think.

That sort of blur effect is more complex and GPU-intensive than puffs of smoke, so it's more likely to cause a framerate hit.

I think the bigger issue is that at high speed, the contrail looks like a bunch of isolated dots instead of a continuous trail.  It'd be better if they were connected.

Perhaps a simple way is to "stretch" the particles in the prograde direction so it looks sort of connected, without making new particles.

It'd probably work better to just replace the particles with a strip of quadrilaterals, like a smoke-textured banner trailing behind the engine.  (Naturally, the texture would have to be animated sliding backward along the strip at the speed that the engine is moving forward.)  The same strip could also be used for the heat-ripple shader effect, if desired.

@BahamutoD has previously done some amazing work on the exhaust refraction you're suggesting:

 

BahamutoD mentioned there's no significant performance hit (apart from specific viewing angles). Would be great to see in the (stock) game.

a few engines

Yeah, except for that one guy who tries to cover the entire KSC in a shower of heat refraction.

Hmm, has he said any latest news about it?

Also, thanks for the feedback.
