I have created heat effect for aircraft.
If i start aircraft on runway - VFX render correctly.
If i shut down engine and then start engine again - VFX ignore any parameters and render incorrectly.
This happen only with VFX_HeatEffect or VFX_Afterburner_heat matterial. With VFX_Debug_Particle i dont have any problem.
Screens for example:
1. Started on RunWay
2. Started on Appron (or shutdown engine on runway and start it again)
