How to keep a vortice from rotating

Recommended Posts

I am trying to keep a vortice from rotating. The effect is for a trail of white compressed air to form over the top of a wing when over Mach1. The problem I am having is that the view of the effect stream rotates with the viewer. Is there a way to 'lock' the bitmap flow effect so that it is level with the vehicle's surface?I need it to look like a blanket forming at the leading edges and flowing up and over the wings and forming a slight trail behind the vehicle.Here is the effect so far in my rough beginnings.//////////////////////////FX START[Library Effect]Lifetime=5Version=1.00Display Name=fx_SlipDrive_QUANTUM[Properties]Virtualcockpit=1Cockpit=1Spot=1Tower=1[Emitter.0]Lifetime=0.00, 0.00Delay=0.00, 0.00Bounce=0.00No Interpolate=1Rate=1.00, 1.00X Emitter Velocity=0.00, 0.00Y Emitter Velocity=0.00, 0.00Z Emitter Velocity=0.00, 0.00Drag=0.00, 0.01X Particle Velocity=0.00, 0.00Y Particle Velocity=0.00, 0.00Z Particle Velocity=0.00, 0.00X Rotation=0.00, 0.00Y Rotation=0.00, 0.00Z Rotation=0.00, 0.00X Offset=0.00, 0.00Y Offset=0.00, 0.00Z Offset=0.00, 0.00[Particle.0]Lifetime=0.40,0.40Type=21X Scale=4.30,4.50Y Scale=0.30,0.50Z Scale=0.00, 0.00X Scale Rate=0.25, 0.30Y Scale Rate=0.25, 0.30Z Scale Rate=0.00, 0.00Drag=-2.00, -1.6Color Rate=0.10, 0.20X Offset=0.00, 0.00Y Offset=0.00, 0.00Z Offset=0.00, 0.00Fade In=0.15, 0.15Fade Out=0.90, 0.90Shade=1Face=0, 0, 0[ParticleAttributes.0]Blend Mode=1Texture=fx_smoke.bmpBounce=0.00Color Start=244, 244, 247, 120Color End=249, 249, 249, 255Jitter Distance=1.00Jitter Time=5.00TempK=107.00TempRate=0.00uv1=0.00, 0.00uv2=1.00, 1.00X Scale Goal=1.00Y Scale Goal=1.00Z Scale Goal=0.00Extrude Length=7.00Extrude Pitch Max=15.00Extrude Heading Max=15.00//////////////////////////FX ENDThe vehicle will have 3, one for a lifting body surface, one each for the two wings.Kind regards and many thanks for any input and help.BillLHC
