Is it possible to add high-g vapor effects to the F-18?
Voodoo:
Well, I've got the first incarnation of the effect mostly the way there. Having trouble orienting it the way I want, but I should be able to sus that out eventually.
The other problem is getting it attached to the model. Just learning all this as I go along, but effects generally seem to start life off as Scenery effects. You want to attach them to a model, the conventional way seems to be to create attach points in the original gmax or 3ds model and attach your effects to those. At this time, we don't seem to have any aircraft MDL editors or exporters to try out that path. Soooo...I am tinkering with existing aircraft lights contact points (although I've really run out of those, what with the Sonic Boom effect and all), so next I'm going to have a tinker with smoke attach points and see what comes out of that.
Then I'm gonna have to learn how to do the XML to control it. LOL ::)
So, maybe something eventually but not for a while yet. And knowing me, the first version of it will not be one that I consider good enough, so probably a second re-worked version is more likely to be the one that sees light of day. And hey, if it's not great, it doesn't matter...I'm having a lot of fun with the learning process. :D
Let us know how you get on though, Raz.
SUBS17:
It might pay to check at what speeds certain effects happen as depending on the vapour if its coming off the wing tips indicates a different speed to when the vapour is coming off the LEX. You can use this in dogfighting to determine roughly what speed the bandit is flying as hes turning. I'm not sure what the specs are for the F/A-18A.
Voodoo:
That's a good point, Subs.
Anybody know what the real conditions are to produce over-wing condensation?
Razgriz:
Don't know but it worked! It was ahead of the aircraft by about two and a half feet. Now lets just move it back and soo perfect.

Heres one effect not related to g
http://en.wikipedia.org/wiki/Prandtl-Glauert_singularity
The LEX and wing is probably high g at high speed eg probably 400kts + and I think the wingtip effect is at lower speeds but the difficult part is the numbers required since its an effect that is influenced by altitude and humidity. I haven't found any solid info on the internet as to what the actual numbers are you might have to talk to an F/A-18 pilot.
