Help with Exhaust Emitter showing in 2D only.

[+ianh755 196]

Hi there, I'm updating the Tornado Storm Shadow bunker buster and, as it's powered by a jet engine (like the Tomahawk etc), I gave it a jet exhaust plume which I'd taken from the TSR2 Olympus (between dirty/clean) but during flight but the effect looks 2d, i.e as you move around in external view the effect "rotates" so it's always flattened. Any idea's on how to make it 3D?

 

 

here's the Modded Olympus effect -

Hey IanH, I took a look at the original Olympus Effect and the different exhaust effects I've done and none of them include the [EffectType001] section. They all start with the [EmitterType001] section.

I had to add that as the "Engine" entry in the weapon data.ini is looking for a Rocket Booster Effect rather than an Exhaust Emitter and it didn't work without it (unless I'm being a total biff!). I swapped the emitter data with the "dirty exhaust emitter" from the Tornado pack and the 2d is gone but now it's repeating flat squares so it looks like I'll just have to keep trying different emitters until I get one I like!

You're using a variant of the "cleanexhaustemitter" effect. That emitter billboards a flat, ribbon-like exhaust effect, hence the appearance of a 2-dimensional ribbon that appears to rotate with a change in viewing angle.

 

The fix is to replace it with another effect, that works with a circular effect, such as this one, that's meant to emulate a very clean exhaust, mostly a sort of heat-blur with a hint of a smoke trail:

 

CleanEmitter.zip

 

Please note that you'll have to change the emitter name on whatever aircraft or weapons you want to use this effect on, to "cleanemitter", as opposed to the "cleanexhaustemitter" that they're probably using now.

Cheers Fubar, that's absolutely spot on!
