Voltic2 "veh_impexp_rocket" PTFX to an addon package ?

[Inglorious_S]

Hi,

I want to convert a replace car to add-on, it's done for basics (carvariations, handling, layouts, vehicles meta files ...). But this car has a functional rocket boost with correct effect in replace version.

In fact the rocket boost works in add-on, but not the ptfx effect. Can you help me to add it in my addon package ?

Thank you in advance !
