Trying to add exaust smoke?

[yellow5 0]

This is an awsome aircraft. I think my favorite part of the aircraft is the exaust stains left on the Nacelles and under the wings. This reminds me of when I worked as a Ramp Rat and one of my jobs was to clean the King Air. Granted it was a 200 series, but still the exaust was a pain to try and remove.Anyway sorry for the rabbit trail. I am trying to add exuast to the engines by using the smoke function ("I" key), but when I do I only get smoke comming out of the left engine, even though I have two lines titled smoke 0 and smoke 1.Thank you for taking the time to assist me. The B1900D is an amazing aircraft to fly. Being a real world pilot, I love the physics you have put into it.Take care,Kevin
