Engine Fire Effect

Sorry, i cant help you with that. Im not even sure you can add this to an existing airplane, i THINK, this only possible when developing an aircraft from scratch. As you need to implement “triggers” aswell, so, WHEN the effect does appear.

Im not sure about all that, but i guess you wont be able to add this to an existing plane. You`d be better off to talk with someone who is actually familiar with the SDK.
